Method and limitations
The calculator estimates monthly simple interest on the starting principal and subtracts optional payments from accrued interest first. It does not model federal program-specific capitalization, subsidies, daily accrual, multiple loans or changing balances.
Check each loan type in your official account. Read the grace-period interest guide before deciding whether to make optional payments.
Educational estimate, not financial advice or a lender payoff quote. FinToku is not a lender. Verify all figures with your lender or servicer. See the financial disclaimer.
Default values are hypothetical US-dollar examples. Replace them with your own loan terms.
Adjust the inputs, then select Calculate to review your scenario.
Compare full loan costs and usable cash
The specialist result above covers its stated question. Use this common worksheet to compare a fixed-rate monthly loan on the same basis as other FinToku tools. Enter every field; use 0 only for a cost that does not apply. Amounts are USD.
No loan summary calculated. Missing costs are not treated as zero.
