Finance Calculators

Free browser-based finance calculators for debt, credit cards, loans, mortgages, savings, investing, pay, budgeting, and business math with explicit assumptions.

Model → compare → stress-check → decide offline

Use the narrowest calculator for the job, compare scenarios with the same assumptions, and keep live lender rates, approvals, taxes, issuer rules, and personalized financial advice outside the static browser model.

Debt & credit cards

Model payoff paths, compare balances, estimate card interest, or test a hypothetical consolidation structure.

Debt Payoff CalculatorEnter a balance, APR, monthly payment, and optional extra payment, then use the connected debt workflow when you need to compare multiple balances or a hypothetical consolidation loan.Debt Avalanche CalculatorCompare an interest-focused payoff order with exact entered balances and minimums while keeping the assumptions visible.Debt Snowball CalculatorAdd multiple debts, apply minimums plus an extra monthly amount, and estimate payoff order, total interest, and debt-free time.Debt Consolidation CalculatorEnter current debts and a proposed consolidation APR/term to compare monthly payment, payoff time, and total interest locally without rate shopping or lender offers.Credit Card Payoff CalculatorEnter the card balance, APR, and payment to estimate payoff cost; use the connected tools for short-period interest or a hypothetical balance-transfer/consolidation comparison.Credit Card Interest CalculatorEstimate daily and period interest from a balance and APR while keeping issuer-specific average-daily-balance rules, fees, transactions, and grace periods outside the model.Balance Transfer CalculatorEnter the current balance/APR and promotional transfer terms to compare modeled costs; no page fetches live card offers or recommends an issuer.Debt to Income Ratio CalculatorCompare gross monthly income with housing and recurring debt payments using user-entered values.

Rates, interest & loan comparison

Separate nominal rate, APR, APY, effective annual rate, implied rate, weighted rate, and fixed-loan comparisons.

Interest CalculatorCompare simple and compound interest using your own principal, rate, term, compounding frequency, and optional recurring contributions.Simple Interest CalculatorCalculate interest and final balance without compounding.Compound Interest CalculatorSee ending balance, contributions, modeled interest, APY, and year-by-year growth, then adjust contribution timing or growth only when the scenario needs it.APR CalculatorUse the established APR calculation, then move to effective-rate tools when compounding frequency rather than upfront finance fees is the comparison question.APY CalculatorEnter a nominal annual rate and compounding frequency to calculate APY, then compare the same compounding effect in the effective-interest-rate workflow.Effective Interest Rate CalculatorEnter a nominal annual rate and compounding frequency to calculate the effective annual interest rate and compounding lift.Interest Rate CalculatorEnter principal, payment, and term to solve the established implied rate, then use connected rate tools to compare compounding or multiple balances.Weighted Average Interest Rate CalculatorEnter balances and annual rates to calculate the exact balance-weighted average rate, total balance, and rate range locally.Loan Comparison CalculatorCompare two fixed-rate loans with the established calculator, then use connected rate tools when your inputs involve fees, compounding, or multiple existing balances.

Mortgage & housing

Estimate mortgage structure, affordability, escrow, PMI, refinancing, payoff, points, buy-downs, and rent-versus-buy scenarios.

Mortgage CalculatorStart with home price, down payment, rate, and term, then add only the housing costs that apply to compare an all-in monthly estimate and payoff path.House Affordability CalculatorModel a monthly housing budget, principal-and-interest capacity, maximum loan, and estimated home price without pretending to predict lender approval.Mortgage APR CalculatorCompare the stated interest rate with an annualized fee-adjusted borrowing-rate estimate using the entered financed amount and payment stream.PMI CalculatorEstimate starting LTV, monthly PMI, modeled PMI months, and total PMI using a transparent user-entered premium rate and LTV stop threshold.Mortgage Escrow CalculatorConvert annual tax, insurance, and optional escrowed charges into a monthly reserve estimate with an editable illustrative cushion.Mortgage Points CalculatorCompare two fixed mortgage rates, point cost, monthly payment difference, break-even months, and estimated savings over a chosen stay period.Mortgage Payoff CalculatorCompare a fixed-rate mortgage schedule with and without an extra monthly principal payment.Refinance CalculatorEstimate payment change, monthly savings, break-even time, and total interest using user-entered assumptions.Rent vs Buy CalculatorProject annual renter and owner costs and estimated owner equity across a chosen horizon so the assumptions stay visible.

Savings, investing & retirement

Project savings and investment assumptions, retirement contributions, present/future value, returns, and deposit scenarios.

Savings CalculatorStart with balance, monthly deposit, APY, and years. Advanced rate conventions, contribution timing, goal solving, saved scenarios, and the yearly schedule remain available below the main result.Savings Goal CalculatorEnter a current balance, target, time horizon, and assumed return to estimate a monthly contribution.Investment CalculatorEnter a starting amount, monthly contribution, annual return assumption, and years. Fees, inflation, contribution increases, goal solving, saved scenarios, and the full projection stay available without crowding the first screen.Compound Interest CalculatorSee ending balance, contributions, modeled interest, APY, and year-by-year growth, then adjust contribution timing or growth only when the scenario needs it.401(k) CalculatorModel employee contributions, employer match, investment return, salary growth, and time using adjustable assumptions.Retirement CalculatorCompare contributions, estimated growth, nominal balance, and today-dollar equivalent across a year-by-year projection without tax-law assumptions.Present Value CalculatorEnter a future target, time period, return assumption, and optional monthly contribution to calculate the required starting value.Future Value CalculatorCalculate projected future value, total contributions, and growth using user-entered assumptions.CD CalculatorModel a fixed-rate CD locally with APY/nominal-rate input, maturity value, interest earned, and a month-by-month balance table without fetching or recommending current bank rates.CD Ladder CalculatorSplit one deposit across 2–8 CD rungs, enter an APY for each maturity, and compare staggered maturity dates, interest, and deposit-weighted APY locally.
