Numbers to enter
Enter today's price, the direct cost that comes with each sale, normal monthly volume and the price increase you are considering. Koala first checks whether the sale is positive after direct cost, then shows the volume boundary where one actually exists.
$

What the customer pays today for one sale/unit.

$

Product/supplier cost plus other costs that rise because the sale happens. Do not include wages or other running costs here.

Use the unit/order volume the price change will affect.

%

10 means a 10% increase.

Koala's Calculated Result
Signed unit economics first; the maximum sales-volume drop only when today's and proposed sales both leave positive contribution.

Add the current price, direct cost, monthly sales and proposed increase.

Frequently asked questions

What does this calculator assume?

It assumes your sales volume holds flat at the current monthly order count. The output is the upside ceiling — the profit lift if customer behaviour does not change.

Impact of a Price Increase

Will demand actually stay flat?

There is no universal numeric benchmark for this decision. The right comparison depends on the industry, geography, business model, time period and exact metric definition. Use the business’s own history, economics and explicit target unless a verified benchmark matching that scope is available.

Impact of a Price Increase

What is the smallest safe price increase?

There is no universal safe number — it depends on how price-sensitive your customers are. A practical rule is to start at 1–3% and measure the volume response. Small moves are easier to roll back than a single large jump.

Impact of a Price Increase

Should I test a price change first?

Yes, if you can. A controlled test on a small segment gives a real read on what the same shoppers will do at the new price before the change rolls out to everyone. Without test traffic, run the smallest defensible increase first and learn from the response.
