Frequently asked questions

Common questions about finance calculators and how to use them.

What calculators are in the Finance section?

Mortgages (payment, refinance, overpayment, amortization), loans (personal, auto, APR, interest rate), interest and savings (simple and compound interest, savings, CD/fixed deposit), and retirement planning (retirement, 401(k), pension, inflation). Each shows the formula and a worked example.

How accurate are these finance calculators?

They are accurate for planning and comparison, and every result comes from a transparent formula shown on the page. Your real figures depend on the exact rate, fees, and terms a lender offers, your credit profile, and local taxes — so confirm anything important before acting.

Do they include taxes, fees, and insurance?

Only where a tool says so. The mortgage calculator can include property tax, insurance, and PMI; most loan tools focus on principal and interest. Add lender fees and local charges yourself to compare offers on equal terms.

Are these financial advice?

No. They are educational tools that show the method behind a number. They are not financial, investment, or tax advice. For decisions that affect your money, speak to a qualified professional.
