Price Increase Calculator
Calculate a new price after a percentage increase and see exactly how much was added. You can also compare an old and new price to find the percentage increase.
Calculate a Price Increase
Enter the original price and percentage increase. The calculator shows the amount added and the resulting new price.
Enter an original price and percentage increase.

How to Calculate a Price Increase
A percentage price increase has two useful results: the amount added and the new price.
You can also calculate the new price in one step:
For example, if a price rises from $100 by 10%, the increase amount is $10 and the new price is $110.
Price Increase Examples
New price = $52.50.
New price = $92.
New price = $300.
| Original Price | Increase | Amount Added | New Price |
|---|---|---|---|
| $20 | 5% | $1 | $21 |
| $50 | 10% | $5 | $55 |
| $80 | 15% | $12 | $92 |
| $100 | 20% | $20 | $120 |
| $200 | 25% | $50 | $250 |
| $500 | 30% | $150 | $650 |
How to Find the Percentage Increase Between Two Prices
Sometimes you know the old price and the new price but not the percentage increase. First find the difference, then divide that difference by the original price.
For example, suppose a product changes from $80 to $100:
The price increased by 25%. Notice that the original price is used as the denominator because the percentage change is measured relative to the starting value.
Understanding the Price Multiplier
A percentage increase can also be expressed as a multiplier. Add 1 to the percentage written as a decimal.
| Increase | Multiplier | Example on $100 |
|---|---|---|
| 5% | 1.05× | $105 |
| 10% | 1.10× | $110 |
| 15% | 1.15× | $115 |
| 20% | 1.20× | $120 |
| 25% | 1.25× | $125 |
| 50% | 1.50× | $150 |
| 100% | 2.00× | $200 |
For example, increasing a price by 20% is equivalent to multiplying the original price by 1.20.
Price Increase vs Percentage Change
A planned percentage increase and a measured percentage change use related mathematics, but they answer slightly different questions.
- Price increase calculation: starts with an original price and a chosen percentage to find a future or adjusted price.
- Percentage change calculation: starts with an old value and a new value to determine how much the value changed relative to the original.
If a value can either rise or fall, the Percentage Change Calculator is useful for calculating both increases and decreases.
Price Increase vs Discount
Increasing a price by a percentage and then reducing the new price by the same percentage usually does not return to the original price because the second percentage is applied to a different starting amount.
For example:
The final amount is $96, not $100. To calculate reductions directly, use the Discount Calculator.
Practical Uses of a Price Increase Calculator
Percentage price calculations can be useful whenever an existing amount is being adjusted upward by a known rate.
- Checking a supplier’s percentage price adjustment.
- Planning a product or service price change.
- Estimating the effect of a percentage increase on a recurring expense.
- Comparing an old listed price with a new one.
- Checking membership, subscription or service-fee increases.
- Preparing simple pricing scenarios for a budget or spreadsheet.
The mathematics is currency-independent. The $ symbol in the calculator is only a visual example; the same percentage calculation works with AED, USD, EUR, GBP or another currency as long as the original and resulting prices use the same currency.
Rounding and Decimal Prices
Percentage calculations can produce more decimal places than are normally displayed in a price. This calculator displays monetary results to two decimal places while performing the calculation using the numerical values entered.
For example, increasing $19.99 by 7.5% produces:
Real billing, tax, accounting or payment systems can have their own rounding rules. If you are reproducing a specific invoice or regulated calculation, use the rounding method required by that system.
Price Increase Calculator FAQs
How do I calculate a price increase?
Multiply the original price by the percentage increase divided by 100 to find the amount added. Then add that amount to the original price.
What is the formula for a new price after an increase?
New price = Original price × (1 + Increase percentage ÷ 100).
What is a 10% increase on $100?
10% of $100 is $10, so the new price is $110.
What is a 20% increase on $80?
20% of $80 is $16. Adding $16 to $80 gives a new price of $96.
How do I find the percentage increase between two prices?
Subtract the old price from the new price, divide the difference by the old price, and multiply by 100.
What multiplier represents a 25% increase?
A 25% increase uses a multiplier of 1.25. For example, $100 × 1.25 = $125.
Is a 100% price increase the same as doubling the price?
Yes. A 100% increase adds an amount equal to the original price, producing twice the original amount.
Does a 20% increase followed by a 20% discount return to the original price?
No. For example, $100 increased by 20% becomes $120. Reducing $120 by 20% gives $96 because the discount is calculated from the higher amount.
Can I use this calculator with AED, EUR or other currencies?
Yes. Percentage price calculations are currency-independent. Use the same currency for the original and resulting values.
How are decimal price results rounded?
The calculator displays monetary results to two decimal places. A specific billing or accounting system may use its own required rounding rules.
