Free tools

Party planning calculators that give you a real answer

How much to buy, what it will cost, and what you should be doing this week. Free, no sign-up, and everything runs in your browser.

How these work

Free, private, and honest about the maths

These are the tools we built for ourselves while making a party planning app. They are useful on their own — no download required.

Nothing is stored, nothing is sent

Every calculator on this page runs entirely in your browser. There is no account, no email box, and no server receiving your guest count.

The method is on the page

Each tool explains how its numbers are worked out, so you can sanity-check them against your own experience instead of trusting a black box.

Answers you can act on

Cases and six-packs rather than servings, pounds and kilos rather than portions, calendar dates rather than 'four weeks before'.

Free on iOS & Android
