Frequently asked questions

How accurate is the loan payment calculator?

It uses the standard fixed-rate amortization formula, the same math lenders use for basic quotes. It doesn't include taxes, insurance, or lender fees, so your actual payment may differ slightly.

Does compound interest include taxes on gains?

No — the result shown is pre-tax growth. Investment accounts may be taxed depending on the account type and your local rules.

Why is the take-home pay estimate only for the US?

Tax systems vary significantly by country. This calculator uses simplified 2024 US federal brackets plus FICA as a starting reference point, and excludes state tax, deductions, and credits.
