Price Increase Impact Calculator
A higher price that loses a few customers can still pay more — and a small rise that halves your volume pays less. This calculator shows the revenue on both sides before you change the price.

What this tool does
Enter the current price and monthly volume, the new price, and the volume change you expect as a percentage — negative when you expect to lose sales. The calculator shows the old and new monthly revenue, the difference, and the break-even volume drop: the largest fall in volume the rise can absorb before the revenue goes backwards.
The volume change is your assumption, labelled as one — no page can know how your customers will react. The tool’s job is to show what has to be true for the rise to pay: if the break-even drop is 10% and you believe you will lose 5%, the rise pays; if you believe you will lose 20%, it does not.
Try it
Waiting. Enter the current price and volume, the new price and the expected volume change, then press Calculate.
How it works
Current monthly revenue is the current price multiplied by the current volume. New volume is the current volume adjusted by the expected change percentage, and new revenue is the new price multiplied by the new volume. The difference is new revenue minus current revenue.
The break-even volume drop is one minus the current price divided by the new price, times one hundred. At that drop, the new revenue exactly equals the old revenue — any larger drop loses money, any smaller one gains.
Assumptions and limitations
The volume change is your assumption. The tool shows what it is worth — it cannot know it.
- Expected volume change is a guess you label as one. No page can know how your customers will react to a higher price — test with a small rise, or a rise on one product, before moving everything.
- The calculator models revenue, not profit. If the new price also changes your costs per sale — packaging, fees, support — the profit picture differs from the revenue picture.
- Volume is monthly sales at the current price. Seasonality matters: a rise tested in a quiet month reads differently from one tested in a busy month.
- The break-even drop assumes the price is the only thing that changes. A rise announced badly, or paired with a worse offer, loses more volume than the price alone explains.
Worked example
Example (illustrative inputs, not a real product). Price 25 to 29, 200 sales a month, expecting a 10% volume fall:
| Item | Figure |
|---|---|
| Current revenue (25 × 200) | 5,000.00 |
| New volume (200 − 10%) | 180 sales |
| New revenue (29 × 180) | 5,220.00 |
| Difference | +220.00 a month |
| Break-even volume drop | 13.8% |
Frequently asked questions
What is the break-even volume drop?
The largest fall in sales the price rise can absorb before monthly revenue goes backwards. At a rise from 25 to 29 it is 13.8%: lose fewer than 13.8% of sales and the rise pays; lose more and it does not.
How do I know what volume change to expect?
You do not — it is an assumption. Test it: raise the price on one product, or for a short period, and watch the actual volume. A small test beats a confident guess.
Does this show profit or revenue?
Revenue. If your costs per sale change with the price — fees, packaging, support — work the profit out separately. A rise that grows revenue can still shrink profit if the volume loss wastes stock or support time.
Should I raise prices often or rarely?
Small, regular rises are easier for customers to absorb than one large jump, and they keep the price moving with costs. A rise that has been delayed for two years is the one that causes the volume shock.
