Tools for you

Budget calculators

Small tools that answer one money question at a time. Nothing you type is sent anywhere — the arithmetic runs in your browser. When you want the answer to stick around month after month. Try it before you start to PAY/ATTN.

5 calculators

Each one answers a single question and nothing else. They read best in this order — what a month leaves you, what that is a day, whether one purchase fits — but they stand on their own.

What PAY/ATTN does with the answer

A calculator gives you one number, once. PAY/ATTN is where that number becomes a plan: count what is coming in, subtract the bills, set savings and investing aside first, and split what is left into a limit per category before the month starts. Then log what you spend against it, by hand, so you actually notice.
