Where the payments go: the 30-year amortization
Early payments are mostly interest: $10,452 of year one’s $11,975 goes to the lender as interest and $1,524 to your balance. The balance below shows the curve.
| After | Remaining balance | Paid down |
|---|---|---|
| 5 years | $141,197 | $8,803 |
| 10 years | $128,719 | $21,281 |
| 15 years | $111,028 | $38,972 |
| 20 years | $85,950 | $64,050 |
| 25 years | $50,399 | $99,601 |
Reaching 80% loan-to-value
If this loan was more than 80% of the home’s original value, private mortgage insurance applies until the balance falls to 80% (cancellation on request) and 78% (automatic). By the schedule alone, with no extra payments or appreciation:
| Starting LTV | Home value | 80% (request) | 78% (automatic) |
|---|---|---|---|
| 97% | $154,639 | month 140 | month 151 |
| 95% | $157,895 | month 130 | month 142 |
| 90% | $166,667 | 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.
Late fees and the 30-day line
On a $997.95 payment, the usual 4% to 5% late fee is $39.92 to $49.90 once the grace period ends. The fee is the small cost; the 30-day credit mark is the large one. If a payment is genuinely at risk, read what to do this month.
How the payment is computed
M = P × r(1 + r)n ÷ ((1 + r)n − 1), where P = $150,000, 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.
