Not financial advice
DebtMathLab provides calculators and articles for general education. Nothing on this Site is financial, investment, tax or legal advice, and using the Site does not create an adviser–client relationship. For advice about your own situation, speak with a qualified, licensed professional.
Results are estimates
Every calculator relies on the numbers you enter and on these assumptions:
- The interest rate stays the same for the whole period.
- Interest is calculated monthly at APR ÷ 12. Many lenders calculate interest daily, which can make small differences.
- Payments are made in full and on time every month.
- No new borrowing, fees, penalties or promotional rate changes.
Your actual payoff date, interest and payments may differ. Always check figures with your lender before making decisions.
Investment returns
The compound interest calculator uses a fixed rate for illustration. Investment returns vary and are never guaranteed; you can lose money.
Advertising
The Site displays ads served by Google AdSense. Ads are clearly labelled. We don’t endorse advertised products, and ads have no influence on calculator results or our content.
No affiliation
We are not a bank, lender, credit counsellor or debt relief company, and we are not affiliated with any card issuer or lender mentioned on the Site. Any names used in examples are for illustration only.
