About | TallyCrunch

TallyCrunch builds focused, high-quality calculators for the moments where a number actually changes your decision — selling online, borrowing, or pricing your work.

Why we built this

Most "calculator" sites bury a simple tool under pop-ups, sign-up walls, and ads, then give you a bare number with no context. We wanted the opposite: a fast, clean tool that shows you the full breakdown, plus a plain-English guide explaining how the number is built and how to improve it.

What we do

E-commerce sellers — see your true profit after Shopify and Amazon FBA fees.
Finance shoppers — understand mortgage payments and loan payoff before you commit.
Freelancers — price your work so the math actually supports the life you want.

Every calculator is paired with an in-depth guide and a clear FAQ.

How it works

Free and instant — no sign-up, no email gate, results as you type.
Private by design — calculations run entirely in your browser; your numbers never reach our servers.
Built for speed — fast pages on every device.

Our editorial approach

We aim for accuracy. Fees, rates, and formulas change, so we explain our assumptions, encourage you to confirm current figures with the relevant provider, and treat every result as an estimate to inform a decision — not financial advice. When we get something wrong, we fix it.

Independent and reader-supported

TallyCrunch is an independent project, funded by advertising and affiliate partnerships. Those relationships never change our calculations or our honest opinion — see our Affiliate Disclosure.
