Price Increase Percentage: Formula, Meaning & Example

Price increase percentage measures how much a price has risen relative to its original value.

If a product’s price increases from $100 to $120:

Price Increase Percentage = (New Price − Old Price) ÷ Old Price × 100

Price Increase Percentage = ($120 − $100) ÷ $100 × 100 = 20%

The price increased 20%.

The denominator is always the old price because the percentage measures the increase relative to the starting value.

This distinction matters because percentage increases and decreases are not symmetrical. A 20% increase from $100 creates a price of $120, but a price decrease percentage of approximately 16.67% is enough to take $120 back to $100.

What Is Price Increase Percentage?

Price increase percentage expresses the difference between an old price and a higher new price relative to the original price.

Suppose a subscription price changes:

Old Price = $80

New Price = $92

Absolute increase:

$92 − $80 = $12

Percentage increase:

$12 ÷ $80 × 100 = 15%

The price increased 15%.

The calculation can be applied to products, services, subscriptions, contracts, hourly rates, procurement prices, fees, rents, or almost any other price that moves upward.

Price Increase Percentage Formula

The formula is:

Price Increase % = (New Price − Old Price) ÷ Old Price × 100

Where:

Old price is the original or previous amount.

New price is the higher current amount.

The absolute price increase is:

Price Increase Amount = New Price − Old Price

Suppose:

Old Price = $250

New Price = $300

Increase:

$50

Percentage:

$50 ÷ $250 × 100 = 20%

The price increased 20%.

Price Increase Percentage Example

Suppose a software company raises its monthly subscription from $50 to $57.50.

Increase:

$57.50 − $50 = $7.50

Price increase percentage:

$7.50 ÷ $50 × 100

= 15%

The subscription price increased 15%.

If 2,000 customers remain on the plan:

Original monthly recurring revenue:

2,000 × $50 = $100,000

New recurring revenue:

2,000 × $57.50 = $115,000

With no customer losses or other changes, monthly recurring revenue also rises 15%.

How to Calculate a Price Increase Step by Step

Suppose an item rises from $160 to $184.

First calculate the dollar increase:

$184 − $160 = $24

Divide by the old price:

$24 ÷ $160 = 0.15

Convert to a percentage:

0.15 × 100 = 15%

The price increased by 15%.

Find the New Price From an Increase Percentage

If the old price and increase percentage are known:

New Price = Old Price × (1 + Price Increase Rate)

Suppose:

Old Price = $200

Increase = 12%

New price:

$200 × 1.12

= $224

The dollar increase is:

$24

Find the Old Price From the New Price

If the new price and increase percentage are known:

Old Price = New Price ÷ (1 + Increase Rate)

Suppose a product now costs:

$138

after a 15% increase.

Original price:

$138 ÷ 1.15

= $120

Check:

$120 × 1.15 = $138

Find the Percentage From the Dollar Increase

Suppose price rises by $30 from an original price of $150.

Price Increase % = $30 ÷ $150 × 100

= 20%

The new price is:

$180

5% Price Increase Example

Old price:

$100

Increase:

5%

New price:

$100 × 1.05 = $105

Dollar increase:

$5

10% Price Increase Example

Old price:

$250

New price after a 10% increase:

$250 × 1.10 = $275

Increase:

$25

20% Price Increase Example

Old price:

$80

New price:

$80 × 1.20 = $96

The price increases by:

$16

25% Price Increase Example

Old price:

$400

A 25% increase produces:

$400 × 1.25 = $500

The dollar increase is $100.

50% Price Increase Example

A price rising from $200 to $300 has increased:

($300 − $200) ÷ $200 × 100 = 50%

The new price is 150% of the original amount.

100% Price Increase Example

A 100% price increase doubles the original price.

Suppose:

Old Price = $75

Then:

New Price = $75 × 2 = $150

The increase is:

$75

or 100% of the starting amount.

Price Increase vs. Price Decrease Percentage

An increase and an equal percentage decrease do not cancel each other.

Suppose price rises 20%:

$100 × 1.20 = $120

A 20% decrease from $120 gives:

$120 × 0.80 = $96

The price ends 4% below its original $100 level.

To return from $120 to $100, the required decrease is:

($120 − $100) ÷ $120 × 100

≈ 16.67%

The asymmetry exists because the percentage base changes.

Increase Required to Reverse a Price Decrease

Suppose price falls 20%:

$100 → $80

To return from $80 to $100:

Required Increase = ($100 − $80) ÷ $80 × 100

= 25%

A 20% decrease therefore requires a 25% increase to reverse.

If price falls 50% from $100 to $50:

Required Increase = 100%

The relationship becomes increasingly important as percentage changes become larger.

Price Increase vs. Discount Percentage

A discount percentage measures a reduction from an original or reference price.

Price increase percentage measures an upward move from an old price to a higher new price.

Suppose a product rises:

$100 → $120

Price increase:

20%

If the seller later applies a 20% discount to $120:

Discounted Price = $96

The product does not return to $100 because the discount is calculated from the new $120 base.

Price Increase vs. Discounted Price

The discounted price is a final price after a reduction.

Price increase percentage measures an upward change.

Suppose regular price increases:

$100 → $110

Increase:

10%

The company then gives a 10% promotional discount:

$110 × 90% = $99

The realized discounted price is actually 1% below the original $100 price.

Sequential percentage changes should therefore be calculated rather than simply offset against one another.

Price Increase and Revenue

Revenue depends on both price and quantity:

Revenue = Price × Quantity

Suppose a company sells:

10,000 Units at $100

Revenue:

$1,000,000

Price rises 10% to:

$110

If unit volume remains unchanged:

Revenue = 10,000 × $110 = $1,100,000

Revenue increases 10%.

But if customers respond to higher pricing by buying fewer units, the revenue increase can be smaller—or revenue can decline.

How Much Volume Can Fall After a Price Increase?

Suppose price increases from:

$100 to $125

The price increase is:

25%

Original volume:

1,000 Units

Original revenue:

$100,000

Units needed at $125 to preserve that revenue:

$100,000 ÷ $125 = 800 Units

Volume can fall from 1,000 to 800:

20% Decline

and revenue remains unchanged.

This shows another percentage asymmetry: a 25% price increase can offset a 20% volume decline.

10% Price Increase and Break-Even Volume

Suppose original price is $100 and original volume is 1,000 units.

Revenue:

$100,000

New price after a 10% increase:

$110

Required units to preserve revenue:

$100,000 ÷ $110 ≈ 909.09

Approximately 910 whole units would generate slightly more than the old revenue.

Volume can fall by roughly 9.09% before revenue reaches the original level.

Price Increase and Margin

Higher pricing can improve margin quickly when unit costs remain stable.

Suppose:

Price = $100

Unit Cost = $70

Original margin amount:

$30

Original margin percentage:

30%

Price rises 10%:

New Price = $110

Cost remains $70.

New margin amount:

$40

New margin percentage:

$40 ÷ $110 × 100 ≈ 36.36%

Price increases 10%, while margin dollars increase:

($40 − $30) ÷ $30 × 100 ≈ 33.33%

Price and profit can therefore change at very different rates.

Price Increase and Break-Even Price

The break-even price identifies the selling price required to cover a defined cost structure at a specified volume.

Suppose:

Current Price = $100

Break-Even Price = $80

The business has:

$20 per Unit

of price above the break-even threshold under those assumptions.

A 10% increase raises selling price to $110, widening that difference to:

$30 per Unit

However, if the higher price reduces volume, the break-even threshold can change because fixed costs may be spread across fewer units.

Price Increase and Monthly Recurring Revenue

Suppose:

1,000 Customers × $100 = $100,000 MRR

Price rises:

10% to $110

If all customers remain:

New MRR = $110,000

MRR increases 10%.

If 100 customers churn:

900 × $110 = $99,000

MRR actually declines 1% from the original $100,000.

The pricing result therefore depends on customer retention.

Price Increase and Monthly Recurring Revenue Growth

A broad recurring price increase can contribute directly to monthly recurring revenue growth.

Suppose:

Beginning MRR = $500,000

A price adjustment adds:

$40,000 MRR

Customer expansion adds:

$20,000

Churn removes:

$15,000

Ending MRR:

$545,000

Growth:

$45,000 ÷ $500,000 × 100 = 9%

Pricing contributed significantly to the 9% recurring-revenue growth rate.

Price Increase and Net Revenue Retention

A price increase applied to existing recurring customers can improve net revenue retention when customers remain.

Suppose:

Starting Cohort MRR = $1M

A 5% price increase would produce:

$1.05M

if everything else remained unchanged.

NRR would therefore be:

105%

But suppose churn and downgrades remove $100,000 after the increase.

Ending cohort MRR:

$950,000

NRR:

95%

The higher price does not guarantee stronger revenue retention.

Price Increase and Gross Revenue Retention

Gross revenue retention excludes expansion and usually focuses on recurring revenue preserved before positive expansion effects.

If a price increase is treated as expansion under a company’s reporting methodology, it does not repair weak GRR.

Suppose customers cancel or downgrade because of the price increase.

Those losses reduce GRR even if retained customers pay more.

This distinction helps prevent pricing gains from masking deterioration in the underlying customer base.

Price Increase and Revenue Churn

Revenue churn can increase if higher prices cause valuable customers to leave.

Suppose recurring revenue initially equals:

$1M

The business raises prices 10%.

Several large customers cancel, removing:

$150,000

of recurring revenue.

The business should not evaluate the pricing change only through the additional dollars generated by retained customers.

The revenue lost to churn must also be incorporated into the economic result.

Price Increase and Customer Churn

Customer churn can reveal whether the higher price affects customer relationships by count.

Suppose:

Starting Customers = 2,000

After a price increase:

100 Customers Cancel

Customer churn:

100 ÷ 2,000 × 100 = 5%

If the customers who leave are small, revenue might still improve substantially.

If they are large enterprise accounts, the revenue result can be much worse.

Count and revenue effects should both be measured.

Price Increase and Logo Retention

Logo retention provides the retained-customer counterpart.

Using the same example:

1,900 Customers Remain

Logo retention:

1,900 ÷ 2,000 × 100 = 95%

A pricing test can therefore be evaluated through:

price increase percentage;

logo retention;

revenue retention;

and total revenue or MRR.

The higher price is only one component of the outcome.

Price Increase and Average Revenue Per Account

If customer count remains stable, a price increase can directly improve average revenue per account.

Suppose:

1,000 Accounts

Monthly Revenue = $500,000

ARPA:

$500

Prices rise 8% across the base with no customer losses:

New Revenue = $540,000

New ARPA:

$540

Average account monetization rises 8%.

If lower-value accounts churn after the increase, ARPA can rise even more while total customer count deteriorates.

Price Increase and Annual Recurring Revenue

Suppose:

ARR = $12 Million

A recurring price increase adds 5% with no customer losses:

New ARR = $12M × 1.05

= $12.6M

Increase:

$600,000 ARR

At scale, relatively small price changes can produce large annualized recurring-revenue effects.

That potential needs to be balanced against churn, contraction, margin, and competitive response.

Price Increase and CAC Payback

A successful pricing increase can shorten CAC payback period by increasing customer gross contribution.

Suppose:

CAC = $2,400

Monthly Revenue per Customer = $300

Gross Margin = 80%

Monthly gross profit:

$240

Payback:

10 Months

Price rises 10% to $330 while gross-margin percentage remains 80%:

Monthly Gross Profit = $264

New payback:

$2,400 ÷ $264 ≈ 9.09 Months

The price increase shortens modeled payback by approximately 0.91 months.

Price Increase and LTV:CAC

Higher customer contribution can also improve the lifetime value to cac ratio when retention remains sufficiently strong.

Suppose estimated LTV is:

$4,000

and CAC is:

$1,000

LTV:CAC:

4:1

A pricing change increases modeled lifetime gross profit to:

$4,500

New ratio:

4.5:1

If the same pricing change significantly increases churn, expected lifetime can fall and offset the higher monthly revenue.

Sequential Price Increases

Price increases compound.

Suppose a $100 price rises 10% and then another 10%.

First increase:

$100 × 1.10 = $110

Second:

$110 × 1.10 = $121

Overall increase:

$21

Overall percentage:

21%

Two sequential 10% increases produce a 21% total increase, not 20%.

Combined Price Increase Formula

For sequential increases:

Final Price = Original Price × (1 + r1) × (1 + r2)

For 10% followed by 20%:

$100 × 1.10 × 1.20

= $132

Combined increase:

32%

not 30%.

Each percentage applies to the price after the preceding change.

Price Increase Followed by a Decrease

Suppose price increases 25%:

$100 → $125

Then decreases 20%:

$125 × 0.80 = $100

In this specific pair, the 20% decrease exactly reverses the 25% increase.

The percentages differ because the second calculation starts from $125 rather than $100.

Inflation and Price Increases

A company may increase prices because supplier costs, labor, rent, logistics, or other expenses rise.

Suppose unit cost increases:

From $60 to $66 = 10%

Selling price remains $100.

Original margin:

40%

New margin:

34%

A price increase may be required merely to preserve the previous dollar or percentage margin rather than improve profitability.

The appropriate increase depends on the entire cost structure.

Price Increase Needed to Preserve Margin

Suppose:

Old Price = $100

Old Cost = $60

Margin:

40%

Cost rises to:

$66

To preserve a 40% margin:

Required Price = $66 ÷ (1 − 0.40)

= $110

Required price increase:

($110 − $100) ÷ $100 = 10%

In this example, the 10% cost increase requires a 10% price increase because the target margin structure and cost proportions align that way.

Other cost structures can produce different results.

Price Increase and Quarter-Over-Quarter Growth

A pricing change can influence quarter-over-quarter growth even if sales volume is flat.

Suppose quarterly units sold remain:

100,000

Average price rises:

From $20 to $22

Quarterly revenue increases:

From $2M to $2.2M

QoQ revenue growth:

10%

All growth came from price rather than quantity.

A growth rate alone does not reveal which component changed.

Price Increase and Month-Over-Month Growth

The same issue applies to month-over-month growth.

If monthly revenue rises 8% immediately after a broad price increase of roughly 8%, underlying transaction volume may have remained flat.

Growth should therefore be decomposed into price, volume, customer count, and mix whenever the distinction matters.

What Is a Good Price Increase Percentage?

There is no universal ideal percentage.

An appropriate increase depends on:

• customer value;
• inflation and costs;
• margin;
• competitive alternatives;
• customer switching costs;
• current pricing relative to the market;
• retention;
• contract terms;
• product differentiation; and
• demand sensitivity.

A 20% increase can be accepted easily for an underpriced product delivering substantial value.

A 3% increase can cause meaningful churn in an intensely competitive commodity market.

The correct percentage depends on customer economics rather than a generic benchmark.

How to Evaluate a Price Increase

A pricing change should not be judged solely by whether the new price is higher.

Useful outcomes include:

revenue change;

MRR or ARR change;

logo retention;

customer churn;

NRR and GRR;

margin;

CAC payback;

and customer feedback.

A successful price increase raises realized economic value without causing enough customer loss or contraction to offset the benefit.

Common Price Increase Percentage Mistakes

A common mistake is dividing the increase by the new price rather than the old price.

Another is assuming an equal percentage decrease reverses an increase.

Sequential increases are sometimes added rather than compounded.

Businesses can also assume the percentage price increase will translate directly into the same percentage revenue increase without considering volume or churn.

Another mistake is evaluating price increases without margin context.

Companies may celebrate higher ARPA while ignoring weaker retention.

Finally, a price increase should be separated from volume, customer mix, and expansion when explaining growth.

Frequently Asked Questions

What is price increase percentage in simple terms?

Price increase percentage measures how much a price rose relative to its previous or original value.

What is the price increase percentage formula?

Price Increase % = (New Price − Old Price) ÷ Old Price × 100

How do you calculate a price increase from $100 to $120?

($120 − $100) ÷ $100 × 100 = 20%

The price increased 20%.

How do you find the new price after an increase?

New Price = Old Price × (1 + Increase Rate)

A 15% increase on $200 gives:

$200 × 1.15 = $230

How do you find the old price from the new price?

Old Price = New Price ÷ (1 + Increase Rate)

If $120 is the price after a 20% increase:

$120 ÷ 1.20 = $100

Is a 20% price increase reversed by a 20% price decrease?

No.

A 20% increase takes $100 to $120.

A 20% decrease from $120 gives $96.

What decrease reverses a 20% increase?

Approximately 16.67%.

($120 − $100) ÷ $120 × 100 ≈ 16.67%

What increase reverses a 20% decrease?

25%.

A 20% decrease takes $100 to $80, and moving from $80 back to $100 requires a 25% increase.

Are two 10% price increases equal to a 20% total increase?

No.

1.10 × 1.10 = 1.21

The combined increase is 21%.

How does a price increase affect revenue?

If sales volume remains unchanged, revenue rises in proportion to price. If customer volume falls, the actual revenue increase can be smaller or negative.

Can a price increase improve margin?

Yes.

When costs remain relatively stable, additional price can increase both margin dollars and margin percentage.

How does a price increase affect MRR?

A recurring price increase raises MRR if retained-customer gains exceed any revenue lost through churn or contraction.

How does a price increase affect NRR?

Higher pricing for retained customers can increase NRR, but resulting churn and contraction can offset the benefit.

Can a price increase reduce CAC payback?

Yes.

Higher customer gross contribution can shorten the time required to recover acquisition cost if retention remains healthy.

Can a price increase improve LTV:CAC?

Yes, when the additional customer contribution increases lifetime value without causing enough churn to offset the benefit.

Why should price increases be analyzed with customer retention?

A larger price generates little benefit if enough customers cancel or downgrade to eliminate the additional revenue.

Why is price increase percentage important?

It provides a standardized way to measure upward pricing changes. Combined with revenue, margin, recurring-revenue growth, retention, and customer-acquisition economics, it helps determine whether higher pricing actually creates stronger business economics.
