Where the payments go: the 30-year amortization
Early payments are mostly interest: $24,832 of year one’s $32,209 goes to the lender as interest and $7,377 to your balance. The balance below shows the curve.
| After | Remaining balance | Paid down |
|---|---|---|
| 5 years | $459,144 | $40,856 |
| 10 years | $406,710 | $93,290 |
| 15 years | $339,420 | $160,580 |

| 25 years | $142,233 | $357,767 |
Reaching 80% loan-to-value
The Homeowners Protection Act sets two thresholds on the original value — 80% on request, 78% automatic. Here is when the regular amortization of this loan reaches them, depending on how much was put down:
| Starting LTV | Home value | 80% (request) | 78% (automatic) |
|---|---|---|---|
| 97% | $515,464 | month 115 | month 125 |
| 95% | $526,316 | month 106 | month 117 |
| 90% | $555,556 | 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.
Late fees and the 30-day line
A payment received after the 15-day grace period typically costs 4% to 5% of the P&I amount — $107.36 to $134.21 here, subject to state limits. Thirty days late is the line that matters for your credit: that is when the delinquency can be reported. Before it happens: the first 72 hours after a missed payment.
The arithmetic behind the table
M = P × r(1 + r)n ÷ ((1 + r)n − 1), where P = $500,000, 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.
