Math made a little easier.
TallyNest is a small collection of straightforward calculators for the questions that come up in everyday life.
Why TallyNest exists
Sometimes you just want to turn an hourly wage into an annual estimate, check what overtime might add to a paycheck, or split dinner without a complicated spreadsheet. That's what TallyNest is for.
We focus on three things: calculations that are easy to use, clear explanations of how the answers are reached, and a thoughtful experience on mobile and desktop.
How our tools work
Our calculators run directly in your browser. When you type a number, your browser performs the calculation and shows the result immediately. The calculations do not require an account or send your inputs to our own server.
Each tool includes its core formula, examples, and assumptions. The salary and overtime tools show gross estimates; they are not replacements for professional tax, legal, or payroll advice.
Our approach
We aim to make the free version genuinely useful. We don't claim that a calculator can replace personalized guidance for employment law or taxes, and we encourage you to verify important decisions against authoritative information.
