| After | Remaining balance | Paid down |
|---|---|---|
| 5 years | $753,053 | $46,947 |

Reaching 80% loan-to-value
PMI ends by the calendar if nothing else changes: you may request cancellation at 80% of the original value and the servicer must cancel at 78%. On this loan’s schedule, those months are:
| Starting LTV | Home value | 80% (request) | 78% (automatic) |
|---|---|---|---|
| 97% | $824,742 | month 140 | month 151 |
| 95% | $842,105 | month 130 | month 142 |
| 90% | $888,889 | month 101 | month 115 |
Extra principal payments or a new appraisal showing appreciation can bring cancellation forward — see PMI removal. FHA mortgage insurance follows different rules.
Missing a payment on this loan
Most mortgages charge a late fee of 4% to 5% of the principal-and-interest payment after a 15-day grace period (state caps vary): on this loan, about $212.90 to $266.12. The costlier consequence comes at day 30, when the servicer may report the payment late to the credit bureaus — a mark that stays seven years. If a payment is genuinely at risk, read what to do this month.
Standard amortization formula
M = P × r(1 + r)n ÷ ((1 + r)n − 1), where P = $800,000, r = 7% ÷ 12 = 0.5833% per month, n = 360 (30 years) or 180 (15 years).
Total interest is M × n − P. The remaining balance after k payments is P(1 + r)k − M((1 + r)k − 1) ÷ r. Every figure on this page comes from these two expressions.
