Finance calculators

CD Calculator

Work out what a certificate of deposit will be worth at maturity: final balance, total interest, and the effective APY for any rate, compounding schedule, and term.

Mortgage Calculator

Estimate your monthly mortgage payment (principal, interest, taxes, insurance, PMI, HOA) and total interest, for any home price, down payment or rate.

Tip Calculator

Work out the tip and per-person total on a restaurant bill, with a toggle for tipping on the pre-tax subtotal vs. the tax-inclusive total and an even split across the table.

Markup Calculator

Solve for selling price, cost, or markup percentage from the other two, and see the corresponding margin percentage every time, since the two are easy to mix up but never equal.

WACC Calculator

Calculate a company's weighted average cost of capital from its equity and debt weights, cost of equity (CAPM or a direct rate), and after-tax cost of debt.
