Debt, budgeting and life insurance
Estimate your monthly student loan payment and total interest, and see how many months and dollars you save by adding an extra payment each month.
This calculator finds your standard monthly payment and shows how an extra monthly payment cuts the interest you pay and the months you stay in debt. It assumes a fixed rate and a fixed repayment term, so it does not model income-driven plans.
Student loan interest is charged on your remaining balance, so every extra dollar you pay above the required amount lowers the balance and the interest that follows. That makes an extra payment worth about the same as earning your loan's interest rate with no risk. Ask your servicer to apply extra payments to principal.
Yes, up to $2,500 a year of qualified student loan interest can be deducted, even if you take the standard deduction. The deduction phases out at higher incomes, based on your modified adjusted gross income (MAGI).
Get your full 401(k) employer match and a three-to-six-month emergency fund first. After that, compare your loan’s interest rate with the after-tax return you could reasonably expect from investing. Loans above 6% to 7% are strong candidates for early payoff.
Estimate the monthly payment, total interest, cash you receive after fees and true APR on a personal or auto loan with an origination fee.
Work out your front-end and back-end debt-to-income ratio and see how it compares with conventional (28/36), FHA (31/43) and Qualified Mortgage limits.
See how many months it takes to pay off your card at a given payment and APR, and how much interest it costs. Raise the payment to compare.
Estimate how much life insurance you need with the DIME method: debts, income replacement, mortgage and education, minus savings and existing coverage.
Enter your monthly take-home pay and see how the 50/30/20 rule splits it into needs, wants and savings or debt payoff.
Estimate your 2026 federal, FICA, state and local income tax, plus your marginal bracket and effective tax rate.
