The same fixed monthly payment continues. Interest is calculated at the entered nominal annual rate divided by 12, then the regular payment is applied. A future extra follows its chosen completed-payment count, before the next interest period.
An extra can use only the remaining principal. Unused planned cash is shown, not spent elsewhere. A future fee is paid separately in full only when positive modeled principal is applied; later events and their fees are skipped after payoff.
Total cash includes regular payments, applied extra principal now and later, and fees paid. Net savings needs two complete payoff estimates and can be negative. Lender rounding, daily accrual, changing rates, legal entitlements and affordability are not modeled. On an unfinished or unevaluated plan, shown cash covers only evaluated actions, not lifetime costs.
No. It means after six completed regular monthly payments and before the next modeled interest period. Actual bank posting dates and interest conventions can differ; check your contract.
Only the remaining principal is applied and the rest is shown as unused. The full entered future fee applies if positive principal is applied. Once already paid off, both the later extra and its fee are skipped.
A non-reducing balance before the first future event is not evaluated, rather than declared impossible to repay. Savings are unavailable without two complete payoff estimates. A tiny positive terminal application may round to 0 while its entered fee still applies.

$750.00 more a month — $1,000.00 instead of $250.00 — clears it in 12 months instead of 6 years and 10 months, and saves you $9,048.65 in interest.
Without extra payment: This monthly model divides the annual nominal interest rate by 12. It assumes fixed payments, no new borrowing and no fees. A total-cost or effective annual rate is a different measure; check the contractual interest rate before entering it.
Check your contract’s payment allocation and fees. This estimate does not reproduce daily interest, lender-specific rounding, future rate changes or other charges.
Scenario cash paid = extra principal + separate fee + future repayments. Net savings = baseline cash paid minus scenario cash paid.
Aggregates are rounded for display to the currency’s smallest unit. The model does not round interest each month.
