Finance Calculators

Yes. The loan, tip and compound interest calculators are completely free with no signup. All calculations run in your browser, so the numbers you enter are never sent to a server.

The loan calculator uses the standard amortization formula: payment = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly payments. It also shows total interest and a monthly or yearly amortization schedule.

The more often interest compounds, the more you earn, because interest starts earning interest sooner. For example, $10,000 at 5% for 10 years grows to about $16,289 compounded annually and about $16,470 compounded monthly. The compound interest calculator supports daily, monthly, quarterly and annual compounding, plus regular monthly or annual contributions.

Open the Tip & Split tab, enter the bill total, pick a tip percentage (5–25% presets or a custom value) and set the number of people (1–50). The calculator shows the tip amount, the total and each person's share, with an optional round-up so everyone pays an even amount.

The math is exact for the inputs you give, but real loans can include fees, taxes, insurance and rate changes that are not modeled. Use the results as estimates for planning, and confirm final figures with your lender or financial institution.
