FAQ
Finance Calculators: common questions
Do these calculators work outside the US?
Yes. Pick your currency on each calculator — the math is the same everywhere. Tools that depend on one country's tax rules say so clearly.
Are the results financial advice?
No. They're estimates based on the numbers you enter, with the formula shown so you can check them. Lenders and advisers use your full situation.
Is my financial information saved?
No. Everything is calculated in your browser and nothing you type is sent anywhere or stored.
