Loan & Debt Calculators
Borrowing has two prices: the payment you feel each month, and the total interest you only see if you look. These calculators show both, and the debt-to-income calculator shows how a lender reads the same numbers.
Loans
Loan Calculator
Find the payment on any fixed-rate loan, see the amortization schedule, and check what paying extra would save.
Auto Loan Calculator
Estimate a car payment with sales tax, fees, a down payment, and a trade-in all accounted for.
Credit cards and payoff
Debt ratios
Reading debt numbers honestly
A longer term almost always lowers the payment and raises the total cost. The two move in opposite directions, and offers emphasise whichever flatters them — comparing on total interest, which every calculator here reports, keeps the comparison honest.
For card debt the number that matters most is the gap between your payment and the monthly interest charge. That gap is the only part actually reducing the balance, and the payoff calculator shows what widening it buys you in months and dollars.
