Equal-Principal vs Equal-Payment Car Loans
There are two main repayment structures for car loans. Equal-principal loans pay the same amount of principal each month — interest falls as the balance decreases, making total interest lower but early payments higher. Equal-payment (annuity) loans keep a fixed monthly payment throughout, making budgeting easier.
Key Differences
Equal-principal: higher initial payments, lower total interest, payments decrease each month. Equal-payment: identical monthly payments, slightly higher total interest, better for cash-flow planning.
Which Should You Choose?
If you have strong early cash flow and want to minimize total interest, choose equal-principal. If predictable monthly payments matter more, or you plan to make lump-sum prepayments, choose equal-payment (annuity).
FAQ
Equal-principal always pays less total interest because the balance shrinks faster, reducing the interest base.
The early balance is the full loan amount, so interest is at its highest. As principal is repaid, interest falls each month.
Equal-payment loans often suit early payoff — lower initial payments keep cash available for lump-sum prepayments when you have extra funds.
