How the calculation works

A clearer way to compare.

For each complete deal group, you pay for X items and receive Y free. Any incomplete group is charged normally until the paid-item requirement is met.

With Buy 2 Get 1 Free at $20 each, six items form two deal groups. You pay for four items ($80) instead of six ($120), saving $40.

Common questions

BOGO / Buy X Get Y FAQ

How accurate is this calculator?

The arithmetic is exact for the values you enter. The practical result depends on whether those prices, quantities, and assumptions match your purchase.

Are taxes included?

Use tax-inclusive prices when tax differs between your options. Otherwise, the comparison remains useful before tax.

Can I use euros, pounds, or another currency?

Yes. Keep every money input in the same currency. The comparison and percentages remain valid even when the displayed symbol differs.

Is any information stored?

No. The calculation runs entirely in your browser and is not sent to a database.
