Free Financial Calculators for Pay, Loans and Saving
Work out what an hourly wage adds up to over a year, estimate a paycheck after federal and state taxes, compare two mortgage offers, or see how long a credit card balance will take to clear. These calculators cover the money questions most US households run into: pay, taxes, home loans, debt, saving, retirement and investing.
Many of them show their working, such as a full amortization schedule you can download as a CSV file, a year-by-year savings balance, or a table comparing credit card payoff time and interest at different monthly payments. Every calculation happens in your browser, so the salary, balances and debts you enter are not sent to our servers, and there is no account to create.
Treat the results as planning estimates, not financial, tax or legal advice. Tax brackets, interest rates and contribution limits change every year, so check important numbers with your lender, the IRS or a tax professional before you act on them.

Pay and salary calculators
Turn an hourly wage into a yearly salary and back, estimate take-home pay after taxes, or see what a raise is worth once inflation is counted. Tracking hours first? The time card calculator totals a week of shifts with lunch breaks and overtime, and the sales commission calculator works out commission pay.
Mortgage and home buying calculators
Estimate a monthly mortgage payment, see how much to put down and when PMI applies, generate a full amortization schedule, and check whether refinancing, or renting instead of buying, makes more sense for you. Lenders also look at your debt-to-income ratio, which the DTI calculator works out for you.
Loan and debt payoff calculators
Work out monthly payments and payoff dates for car loans, student loans and credit cards, and see how much interest an extra payment each month saves. The APR calculator shows the true yearly cost of a loan once fees are included.
Savings and retirement calculators
See how compound interest grows a balance, how much to save each month for a goal or an emergency fund, and where a 401(k) or IRA could stand by retirement. Parents can project 529 plan growth against the future cost of college.
Tax calculators
Estimate federal income tax with your marginal and effective rate, self-employment tax on 1099 income, capital gains tax on a sale, and sales tax on a purchase. Check the tax year shown on each tool, since brackets and limits change every year.
Investing and rental property calculators
Measure return on investment, project stock and dividend income with reinvestment, and size up a rental property with monthly cash flow, cash-on-cash return and cap rate.
Everyday money and small business calculators
Quick answers for tips, discounts, appliance running costs, trip fuel costs and a wedding budget, plus profit margin and break-even math for small sellers. For itemized bills, the split bill calculator assigns each dish to the person who ordered it, and the currency viewer uses approximate reference rates rather than live market rates.
Frequently asked questions
How do I convert an hourly wage to a yearly salary?
Multiply your hourly rate by the hours you work in a year. A full-time schedule of 40 hours a week for 52 weeks is 2,080 hours, so $25 an hour comes to $52,000 a year before taxes. The hourly to salary calculator uses your own hours and weeks and also shows weekly, biweekly and monthly pay.
What is the difference between APR and APY?
APR (annual percentage rate) is the yearly cost of borrowing, and it can include lender fees as well as interest. APY (annual percentage yield) is what a savings account or CD earns in a year once compounding is counted, so it is the better number for comparing savings accounts. Use the APR calculator for loans and the APY calculator for savings.
How much should I keep in an emergency fund?
A common guideline is three to six months of essential expenses, such as rent, groceries, insurance and minimum debt payments. People with irregular income, or a household that relies on one income, often aim for the higher end. The emergency fund calculator turns your monthly costs into a target and shows how long it will take to build.
How accurate are these financial calculators?
They use standard formulas, such as the amortization formula for loans and the compound interest formula for savings. Real outcomes also depend on things no calculator can know, like future interest rates, fees and changes to tax law, so use the results for planning and confirm big decisions with your lender or a tax professional.
