Financial calculators that show you the real number
The figure on your loan offer, your payslip or your credit card statement is rarely the figure that matters. Our calculators do the arithmetic behind it — total interest, take-home pay, payoff dates — so you can decide with the full picture instead of the headline.

Why Calcmywallet
Built the way a calculator should be
Genuinely private
Every calculation runs inside your browser. Your salary, your debts and your loan figures are never sent to us, logged, or stored anywhere.
Instant, not submit-and-wait
Move a slider and everything recalculates immediately, so you can test a dozen scenarios in under a minute instead of reloading a form.
The full picture
Not just a monthly payment — total interest, payoff dates, a chart of where the money goes, and a schedule you can download.
Not just for one country
Multiple currencies and editable tax bands, so the tools stay useful whether you are in New York, London, Toronto, Karachi or Dubai.
How it works
Three steps, no sign-up
Pick your calculator
Choose the tool that matches your question — borrowing, income, or paying down debt.
Enter your own numbers
Type them or drag the sliders. Set your currency and, where it applies, your local tax rates.
Read the whole result
Check the totals, not just the monthly figure. Download the schedule if you want to keep it.
Understand the number, not just the output
Our guides explain the mechanics behind the maths — why amortization front-loads interest, why your marginal rate is not your effective rate, and what actually drives the cost of borrowing.
Common questions
Before you start
Are these calculators really free?
Yes. Every tool on Calcmywallet is free to use with no limits, no trial period and no account. The site is supported by advertising, which is what keeps the calculators themselves free.
Do you store the numbers I enter?
No. The calculators run entirely in your browser using JavaScript — your salary, loan amounts and debt balances are processed on your own device and are never transmitted to our servers. Close the tab and the figures are gone. There is no database of your inputs because the inputs never reach us.
How accurate are the results?
The arithmetic is precise, but the result is only ever as good as the assumptions. Our tools deliberately exclude things they cannot know — lender fees, property taxes, insurance, statutory contributions and local tax rules — and each calculator states its assumptions directly beneath the results. Treat every figure as a well-informed estimate, and confirm the final numbers with your lender or employer.
Can I use these outside the United States?
Yes. Every calculator supports multiple currencies, and the salary tool uses editable tax bands rather than one country's hard-coded system. You will need to enter the rates that apply where you live — the default values are illustrative examples, not current statutory rates.
Is this financial advice?
No. Calcmywallet is an educational tool, not a licensed adviser, lender or broker. Nothing here is financial, tax or legal advice, and no adviser–client relationship is created by using the site. For decisions that matter, speak to a qualified professional who knows your full circumstances.
