About BudgetBench
BudgetBench is the monthly arithmetic most people never run: what a 50/30/20 split of your real income looks like, where your actual spending breaks it, and how big the emergency fund should be.
BudgetBench exists because budgeting fails as advice and works as arithmetic. "Spend less" is a slogan; seeing that your take-home supports $2,400 of rent and $900 of wants is a decision — and it takes one calculator page to see it.
Every calculator on BudgetBench shows its formula and its assumptions on the page, so you can check the math, reproduce it in a spreadsheet, or argue with it. Inputs are processed entirely in your browser — nothing is sent to a server, and there are no accounts.
BudgetBench is an independent, ad-supported project. We are not affiliated with any lender, brand, agency, or the sources we cite (IRS and CFPB public guidance). If a number looks wrong, the contact page reaches a human who fixes it.
What makes BudgetBench different
- Your numbers never leave your browser. Every calculator on BudgetBench runs entirely on your device. We never see, store, or transmit the figures you enter — there are no accounts and no server-side processing of your inputs.
- Published methodology. Each calculator page explains the exact formula it uses and the assumptions behind it, so you can check our work or reproduce it in a spreadsheet.
- Free, forever, without a paywall. BudgetBench is supported by advertising. There is no premium tier, no email gate, and no upsell.
