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.
How fast the balance falls
In the first year, $19,925 of the $22,013 you pay is interest; only $2,088 reduces the balance. The split reverses slowly: by year 15 most of each payment is principal.
| After | Remaining balance | Paid down |
|---|---|---|
| 5 years | $237,675 | $12,325 |
| 10 years | $219,312 | $30,688 |
| 15 years | $191,954 | $58,046 |
| 20 years | $151,195 | $98,805 |
| 25 years | $90,470 | $159,530 |
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 152 | month 163 |
| 95% | $263,158 | month 142 | month 154 |
| 90% | $277,778 | month 112 | month 127 |
Extra principal payments or a new appraisal showing appreciation can bring cancellation forward — see PMI removal. FHA mortgage insurance follows different rules.
What a late payment costs
A payment received after the 15-day grace period typically costs 4% to 5% of the P&I amount — $73.38 to $91.72 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 = $250,000, r = 8% ÷ 12 = 0.6667% 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.
