FAQ
Frequently Asked Questions
How do I calculate a price increase in percent?
Price increase percentage equals (new price minus old price) divided by old price, times 100. For example, a product going from 10 to 12 euros has a 20% price increase.
How can I identify hidden price increases?
Watch for shrinkflation (same price, smaller quantity), changes in product composition, removal of features, or changes in terms and conditions. Always check the price per unit.
Are my entered amounts stored anywhere?

Enter the current price and percentage increase. The calculator determines the new price. Optionally enter the price elasticity to estimate the expected change in volume and revenue effect.
Key Data and Facts
New price = old price * (1 + increase / 100). For multiple increases multiply, do not add. Inflation adjustment: real change = nominal minus inflation.
Step-by-Step Guide
How to calculate a price increase step by step: 1. Enter the current price: the previous selling price of your product or service. 2. Specify the increase percentage: e.g. 5 % for inflation or rising costs. 3. Calculate the new price: New price = Old price x (1 + increase/100). 4. For multiple increases: multiply one after another. Two increases of 5 % each do not amount to 10 %, but rather: 1.05 x 1.05 = 1.1025 = 10.25 %. 5. Determine the real price change: nominal increase minus inflation rate. Only the portion above inflation is a genuine price increase. 6. Estimate the revenue effect: with a known price elasticity: change in sales = -elasticity x price increase. Example: a product currently costs 29.90 EUR. Price increase 8 %. New price: 29.90 x 1.08 = 32.29 EUR. Increase in EUR: 2.39 EUR. Real increase (with 2.2 % inflation): 8 % - 2.2 % = 5.8 %. Revenue effect with an elasticity of -1.5 and previous sales of 1,000 units: drop in sales: 1.5 x 8 % = 12 %. New sales: 880 units. Old revenue: 29,900 EUR. New revenue: 880 x 32.29 = 28,415 EUR.
Calculation Example
Product EUR 29.90, 8% increase. New price: EUR 32.29. Real increase (less 2.2% inflation): 5.8%. With elasticity -1.5: sales decline 12%, new sales 880 instead of 1,000 units.
