If volume holds, profit rises from $4,800 to $6,400 — a 33.3% increase, for no extra work.
How the Price Increase Impact Calculator works
Price rises are feared more than they deserve. Because the increase falls entirely into margin, you can usually lose a surprising share of volume and still be better off — and this shows exactly how much.

Frequently asked questions
How much volume can I lose after a price rise?
More than most people expect. On a 30% margin, a 10% price rise means you could lose a quarter of your volume and still make the same profit — while doing less work and shipping fewer orders.
Why does a price rise increase profit so much?
Because it costs nothing to deliver. A 10% rise on a 30% margin lifts profit by a third, since the extra revenue carries no additional cost with it. Cost reductions of the same percentage produce far less.
How should I communicate a price increase?
In advance, with a reason, and with a window to buy at the old price. Silent increases get noticed and resented; explained ones are usually accepted. Improving something at the same time helps considerably.
How often should I raise prices?
At least annually in line with costs. Sellers who avoid it for years face a choice between a painful one-off rise and slow margin erosion — and inflation makes the second option a real-terms cut.
