Price Increase Percentage Calculator
A Price Increase Percentage Calculator measures how much a price has risen from its earlier value. It compares the original price with the updated price and expresses the change as a percentage of the starting amount.
This calculation is useful when products, services, subscriptions, bills, rent, supplier charges, or operating expenses become more costly. For broader old-to-new comparisons, use the Percentage Change Calculator. For increases in any value, the Percentage Increase Calculator follows the same core method.
Quick example
When a product moves from $50 to $65, the dollar increase is $15. Compared with the original $50 price, that change equals a 30% price increase.

Calculate Price IncreaseWhat Is a Price Increase Percentage Calculator?
This calculator finds the percentage rise between an earlier price and a newer price. It shows the amount added, how much higher the updated price is, and the scale of the increase relative to the original price.
Price-increase percentages are commonly used in shopping, ecommerce, retail management, supplier negotiations, rent reviews, budgeting, accounting, inflation monitoring, and business planning.
Monitor Cost Pressure
Track higher supplier charges, subscriptions, rent, utilities, and everyday spending.
Support Pricing Decisions
Evaluate how a proposed selling price differs from the current one before applying it.
Simple example
An old price of $100 and a new price of $125 produce a $25 increase, equal to a 25% rise.
Price Increase Percentage Formulas
The old price is the calculation base because the increase is measured from the amount at which the price started.
Price increase percentagePrice Increase % = ((New Price − Old Price) ÷ Old Price) × 100
The old price is the earlier value, the new price is the updated value, and subtracting the two gives the increase amount.
New price after a known increaseNew Price = Old Price × (1 + Increase % ÷ 100)
A 15% increase on $100 is 100 × 1.15 = 115. The revised price is therefore $115.

Use the CalculatorHow to Calculate a Price Increase by Hand
Write Down the Old Price
Start with the earlier amount. Example: $80.
Write Down the New Price
Record the updated amount. Example: $100.
Find the Increase Amount
Subtract the old price from the new price: 100 − 80 = 20.
Divide by the Old Price
Compare the increase with the original base: 20 ÷ 80 = 0.25.
Convert the Result to a Percentage
Multiply by 100: 0.25 × 100 = 25%. The price rose from $80 to $100 by 25%.
Worked Price Increase Examples
Product Price Increase
A product rises from $40 to $50. The difference is $10, and (10 ÷ 40) × 100 = 25%. The selling price increased by 25%.
Rent Increase Percentage
Monthly rent changes from $900 to $990. The increase is $90, and (90 ÷ 900) × 100 = 10%. The rent rose by 10%.
Higher Material Cost
A material previously cost $18 per unit and now costs $22.50. The increase is $4.50, and (4.50 ÷ 18) × 100 = 25%. The business can use this result when reviewing prices, negotiating, or reducing other costs.
Subscription Price Increase
A monthly plan rises from $12 to $15. The $3 change equals (3 ÷ 12) × 100 = 25%. Although the dollar amount is small, the relative increase is substantial.
Price After a 12% Increase
A product costs $250 and is raised by 12%. Calculate 250 × 1.12 = 280. The new price is $280, which is $30 higher.
How to Use the Price Increase Percentage Calculator
Provide the earlier price and the updated price, then calculate the result. The tool returns both the price difference and the percentage increase.
Old Price
The amount before the increase. It may also be described as the original, previous, base, or starting price.
New Price
The amount after the increase. It may also be called the updated, current, raised, or final price.
Increase Amount
The actual money difference found by subtracting the old price from the new price.
Increase Percentage
The size of the increase relative to the old price, expressed as a percentage.
With an old price of $60 and a new price of $75, the increase is 25%.
Important
Compare the same product, package size, currency, unit, and price basis. A comparison is misleading when one amount includes tax or fees and the other does not.
Price Difference vs Price Increase Percentage
These two results are related, but each communicates something different.
Price Difference
This is the actual amount added. For example, $120 − $100 = $20.
Price Increase Percentage
This shows the increase relative to the starting price. For example, $20 ÷ $100 × 100 = 20%.
Both are valuable. A $20 increase may be minor on a $1,000 item but very large on a $40 item. The percentage supplies that missing context.
Price Increase vs Markup
Price increase, markup, and profit margin can appear similar, but each uses a different comparison base.
| Calculation | What It Compares | Best Tool |
|---|---|---|
| Price increase | Old selling price versus new selling price | Price Increase Percentage Calculator |
| Markup | Cost price versus selling price | Markup Calculator |
| Profit margin | Profit versus selling price or revenue | Profit Margin Calculator |
Use price increase percentage for an old-versus-new selling price. Use the Markup Calculator when setting a selling price from cost.
Applications of Price Increase Percentage
Retail and Ecommerce
Review product updates, seasonal changes, supplier-driven adjustments, and revised selling prices. For markdowns, use the Discount Calculator or Sale Price Calculator.
Business and Procurement
Measure supplier increases and judge whether a cost movement is limited, moderate, or serious.
Personal Budgeting
Track changing grocery, subscription, utility, transport, housing, and household expenses.
Housing and Rent
Compare old rent with new rent and understand lease adjustments or annual increases.
Manufacturing
Monitor increases in materials, labor, packaging, freight, energy, and equipment costs.
Taxes and Fees
Review how added charges affect final prices. For tax calculations, use the Sales Tax Calculator, VAT Calculator, or GST Calculator.
Tips for Accurate Price Increase Calculations
Use the Old Price as the Base
Divide by the original price, not the updated one.
Keep the Currency Consistent
Convert currencies first rather than comparing unlike money values.
Compare the Same Product
Use identical models, services, plans, or specifications.
Check Unit Prices
Compare per-unit prices when package weights or quantities differ.
Treat Taxes Consistently
Ensure both prices either include or exclude the same taxes and fees.
Round Only at the End
Keep full precision throughout the working and round the final output.
Separate Markup From Price Increase
Remember that markup begins with cost, while price increase begins with the old selling price.
Compound Repeated Increases
Each later increase applies to the already-updated price, so repeated percentages should not simply be added.
Two successive 10% increases produce 1.10 × 1.10 = 1.21, which is a total rise of 21%, not 20%. The Compound Percentage Change Calculator is designed for this situation.
Common Price Increase Calculation Mistakes
Dividing by the New Price
The correct base is the old price: (New Price − Old Price) ÷ Old Price × 100.
Confusing the Amount With the Percentage
A $10 rise from $20 to $30 is 50%, while the same $10 rise from $200 to $210 is only 5%.
Comparing Different Package Sizes
When quantities differ, calculate and compare the unit price before measuring the increase.
Mixing Tax-Inclusive and Tax-Exclusive Prices
A fair comparison requires both amounts to follow the same tax and fee basis.
Using Markup Instead of Price Increase
Markup compares cost with selling price; price increase compares an old selling price with a new one.
Adding Repeated Increases Directly
A second increase applies to the first revised amount, so compound the changes rather than adding the rates.
Frequently Asked Questions
What is a Price Increase Percentage Calculator?
It compares an original price with an updated price and expresses the rise as a percentage of the original amount.
How is price increase percentage calculated?
Subtract the old price from the new price, divide by the old price, and multiply the result by 100.
((New Price − Old Price) ÷ Old Price) × 100
What is the percentage increase from $80 to $100?
The difference is $20. Dividing $20 by $80 and multiplying by 100 gives a 25% increase.
How can I apply a 10% price increase?
Multiply the old price by 1.10. For example, $50 × 1.10 gives a new price of $55.
How do I find the new price after a 15% increase?
Multiply the original amount by 1.15. A $200 price becomes $230.
Is price increase percentage the same as percentage change?
It is the positive-growth form of percentage change. When the new price is lower, the result is a price decrease instead.
Is a price increase the same as markup?
No. A price increase compares two selling prices, while markup compares cost with selling price. Use the Markup Calculator for markup.
What does a 25% price increase mean?
The increase equals one quarter of the old price. A $100 item with a 25% rise becomes $125.
How do I calculate a rent increase percentage?
Subtract the previous rent from the new rent, divide by the previous rent, and multiply by 100. For example, rent rising from $1,000 to $1,100 is a 10% increase. The Rent Increase Percentage Calculator provides a dedicated version.
Can a price increase exceed 100%?
Yes. When the new price is more than twice the old price, the increase is over 100%. A move from $50 to $120 equals 140%.
What happens when the new price is lower?
That is a decrease rather than an increase. Use the Percentage Decrease Calculator to measure the drop.
Why is the old price used as the base?
It is the starting point from which the price moved, so the increase must be measured relative to that value.
Final Note
A Price Increase Percentage Calculator gives a clear view of how much a price has gone up. It can be used for products, rent, supplier expenses, subscriptions, bills, fees, and other business or household costs.
Enter the old price and the new price to see both the percentage rise and the money difference.
