The Calculator App
Make Smarter Financial Decisions.
Free calculators for exploring borrowing, investing, savings, and other large financial decisions. Change the inputs and read the estimate. Results are not loan offers or financial advice.
Mortgage calculator
Estimate a monthly payment, a payoff date, and cash to close. The full calculator includes taxes, mortgage insurance, extra principal, closing costs, and an amortization schedule.
- Scheduled principal and interest, plus the costs you choose to include
- Extra-payment and payoff comparison on the same scenario
- A payment-by-payment schedule you can export
Home affordability
Estimate a purchase budget from income, monthly debts, and cash you want to keep in reserve. The result is a planning range, not a preapproval.
Open the home affordability calculatorRent vs. buy
Compare the net cost of renting with buying over a horizon you choose, including opportunity cost and selling costs. A lower net cost in the model is not a recommendation to buy or rent.
Open the rent vs. buy calculatorLoan
Estimate payment, interest, and payoff on a fixed-rate amortized loan from the amount and APR you enter. A lower payment from a longer term is not treated as a lower cost.
Open the loan calculatorHome equity
Estimate equity, max borrow, and HELOC or home equity loan payments from values you enter. A higher max borrow in the model is not a lender approval.
Open the home equity calculatorMortgage refinance
Compare keeping a current loan with a new fixed-rate loan, including closing costs, break-even, and a cash-out case. A lower payment is not treated as a guaranteed saving.
Open the refinance calculatorAuto loan
Estimate a vehicle payment, trade-in equity, and the interest on a fixed-rate monthly loan. A lower payment from a longer term is not treated as a lower cost.
Open the auto loan calculatorCredit card payoff
Estimate how many months a card balance takes to pay off and what it costs in interest, with a minimum-versus-fixed comparison and a balance transfer what-if. A paid-off date in the model is not a statement from your issuer.
Open the credit card payoff calculatorStudent loan
Compare standard, graduated, and extended repayment plans for a balance and rate you enter, plus a rough income-based estimate. A lower payment is not treated as a lower cost, and nothing here is an eligibility check.
Open the student loan calculatorARM calculator
Estimate an adjustable-rate payment from a starting rate, a product, caps, and a scenario rate. Later payments follow that scenario. They are not a forecast of a future index.
Open the ARM calculatorMortgage payoff
See how extra principal changes the payoff date on a fixed monthly loan. The scheduled payment stays the same. This is not a payoff quote from a servicer.
Open the mortgage payoff calculatorDebt payoff
Compare a highest-rate order with a smallest-balance order for the balances and minimums you enter. A lower interest total in the model is not a payment plan from a creditor.
Open the debt payoff calculatorInvestment property
Estimate rental cash flow from rent, vacancy, operating expenses, and a fixed-rate loan payment. A lower loan payment is not treated as a higher return after tax.
Open the investment property calculatorInflation
See how an inflation rate you enter changes future costs and purchasing power over a horizon you choose. The rate is never pulled from official CPI data on this page.
Open the inflation calculatorSavings goal
Estimate the deposit needed to reach a goal by a target date, or how long it takes at a fixed deposit and return you enter. A higher return in the model is not a forecast.
Open the savings goal calculatorRoth IRA
Project a Roth IRA balance at retirement and a simplified Roth vs traditional after-tax comparison from tax rates and limits you enter. Nothing here is tax advice or an eligibility check.
Open the Roth IRA calculatorCompound interest
Project a balance from a starting amount, contributions, and a rate you enter. A higher rate in the model is not treated as a forecast of an investment return.
Open the compound interest calculatorRetirement
Project savings toward a goal from a current balance, monthly contributions, and a rate you enter. A higher balance in the model is not treated as a retirement plan.
Open the retirement calculator401(k)
Project a 401(k) balance at retirement from your contribution, an employer match, and a return you enter. A higher balance in the model is not a forecast or investment advice.
Open the 401(k) calculatorEmergency fund
See how much of an essential-expense target is already saved, and when a monthly contribution reaches it. The month count is a rule of thumb you can change, not a requirement.
Open the emergency fund calculatorBudget
Split monthly take-home pay into needs, wants, and savings, and compare optional actual spending. The split is a preset you can change, not a budget you must follow.
Open the budget calculatorHigh-yield savings
Project a savings or CD balance from an APY, compounding, and deposits you enter. Rates are numbers you type, not live quotes, and interest may be taxable.
Open the high-yield savings calculatorNet worth
Add the assets and debts you enter, then see a simple projection. The snapshot is not a statement of what you own.
Open the net worth calculatorFIRE
Estimate a financial-independence number from spending and a withdrawal rate you choose, and how many years of saving reach it.
Open the FIRE calculatorCollege savings
Compare example college costs with monthly savings. The tuition figures are examples, and 529 tax benefits are not calculated.
Open the college savings calculatorSocial Security
A rough monthly benefit at 62, full retirement age, and 70. Check your statement at ssa.gov. This is not an official benefit calculation.
