Simple, honest calculators for the everyday money questions of running a small business.
Most business calculators online are buried under pop-ups or ask for your email before showing a result. TallyKit takes a different approach: every tool works instantly, shows the formula behind the answer and includes a worked example so you can verify it.
Each calculator is built from standard accounting and finance formulas and tested against hand-worked examples. Tax figures (such as federal brackets, the standard deduction and the Social Security wage base) are updated when the IRS publishes new numbers. If you spot an error, please let us know and we'll fix it quickly.
Our results are estimates for planning. For decisions about taxes, payroll compliance or financing, check with a qualified accountant or advisor.
TallyKit is free to use. In the future we may show advertising or recommend software we think is useful, and some links may be affiliate links. That never changes how a calculator works or the results it shows.
