Mortgage insurance: the months that matter
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% | $154,639 | month 115 | month 125 |
| 95% | $157,895 | month 106 | month 117 |
| 90% | $166,667 | month 79 | month 92 |
Extra principal payments or a new appraisal showing appreciation can bring cancellation forward — see PMI removal. FHA mortgage insurance follows different rules.
The price of paying late
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 $32.21 to $40.26. 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. See what happens at 30, 60, 90 and 120 days.
Standard amortization formula
M = P × r(1 + r)n ÷ ((1 + r)n − 1), where P = $150,000, r = 5% ÷ 12 = 0.4167% 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.
