Financial Calculators
Mortgage, loan, interest, and investment calculators to plan your money with confidence.
- Mortgage CalculatorEstimate your full monthly mortgage payment — principal, interest, property tax, home insurance, PMI, HOA, and other costs — plus total interest, total cost, and the amortization schedule.
- Loan CalculatorCalculate loan payments three ways: an amortized loan's periodic payment and total interest, a deferred loan's lump sum due at maturity, or a bond's present value — with adjustable compounding.
- Compound Interest CalculatorSee how an investment grows with compound interest. Enter the starting amount, annual rate, term, and compounding frequency to get the ending balance, total interest, and effective annual rate (APY).
- Interest CalculatorCalculate compound interest on an initial investment plus regular contributions. See the ending balance, total interest, the interest split, and an inflation-adjusted buying power.
- Payment CalculatorFind a fixed-rate loan's monthly payment from its term, or how long it takes to pay off at a fixed monthly payment — with total interest and a full amortization schedule.
- Retirement CalculatorPlan retirement four ways: how much you need saved, the monthly savings to reach it, the sustainable withdrawal your savings support, and how long a pot of money will last.
- Amortization CalculatorBuild a loan amortization schedule with the monthly payment, total interest, and payoff date — and see how optional extra payments shorten the term and cut total interest.
- Investment CalculatorSolve any one variable of an investment plan — end balance, required contribution, return rate, starting amount, or length — with a full accumulation schedule and balance breakdown.
- Inflation CalculatorConvert a dollar amount between years using U.S. CPI data, or project purchasing power forward and backward at a flat average inflation rate.
- Finance CalculatorA five-key time value of money calculator: solve for future value, present value, periodic payment, number of periods, or interest rate, with a full period schedule.
- Income Tax CalculatorEstimate your U.S. federal income tax refund or amount owed for 2025 or 2026 — from wages, self-employment, and investment income through deductions, credits, FICA, and withholding.
- Salary CalculatorConvert a salary between hourly, daily, weekly, bi-weekly, semi-monthly, monthly, quarterly, and annual pay — with a holidays-and-vacation-adjusted column.
- Sales Tax CalculatorCalculate sales tax and the before- or after-tax price. Enter any two of the before-tax price, tax rate, and after-tax price to solve for the third.
- Interest Rate CalculatorFind the interest rate on a loan from the loan amount, term, and monthly payment. See the APR, total payments, total interest, and a full amortization schedule.
- Auto Loan CalculatorCalculate your car loan's monthly payment, amount financed, sales tax, total interest, and total cost — or find the auto price you can afford from a target payment.
