Principal and interest only. Property taxes, homeowners insurance, mortgage insurance and HOA dues are added to the actual payment. Rates shown are for the arithmetic, not an offer; see 30-year vs 15-year for how to choose.
Where the payments go: the 30-year amortization
In the first year, $17,420 of the $19,959 you pay is interest; only $2,540 reduces the balance. The split reverses slowly: by year 15 most of each payment is principal.
| After | Remaining balance | Paid down |
|---|---|---|
| 5 years | $235,329 | $14,671 |
| 10 years | $214,531 | $35,469 |
| 15 years | $185,047 | $64,953 |
| 20 years | $143,250 | $106,750 |
| 25 years | $83,998 | $166,002 |
Mortgage insurance: the months that matter
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% | $257,732 | month 140 | month 151 |
| 95% | $263,158 | month 130 | month 142 |
| 90% | $277,778 | 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.
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 $66.53 to $83.16. 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. Behind already?

The formula
M = P × r(1 + r)n ÷ ((1 + r)n − 1), where P = $250,000, r = 7% ÷ 12 = 0.5833% per month, n = 360 (30 years) or 180 (15 years).
Same formula every lender uses; differences between quotes come from the rate, points and fees, never from the arithmetic. Balance after k payments: P(1 + r)k − M((1 + r)k − 1) ÷ r.
