Case Study: 30-Year Fixed vs. 15-Year Fixed Comparison ($400,000 Home)
Assuming a $400,000 home with 20% down ($80,000) and a $320,000 loan amount, here is how a 30-year loan compares to a 15-year loan:
| Loan Term | Benchmark Rate | Monthly P&I | Total Lifetime Interest | Lifetime Savings |
|---|---|---|---|---|
| 30-Year Fixed | 7.32% | $2,200 | $471,987 | Baseline |
| 15-Year Fixed | 6.50% | $2,789 | $182,109 | Save $289,878 |
*Key Takeaway: While the 15-year fixed payment is approximately $589 higher per month, you save nearly $290,000 in pure interest over the lifespan of the loan.
Frequently Asked Questions (FAQ)
Q. What does PITI stand for in homeownership?
PITI represents Principal, Interest, Taxes, and Insurance. It encompasses the four core components of an escrowed monthly mortgage payment in the United States.
Q. How does Private Mortgage Insurance (PMI) work and when can it be removed?
If your down payment is less than 20%, conventional lenders require PMI to mitigate default risk. Annual PMI typically costs between 0.5% and 1.2% of the original loan balance. By federal law (Homeowners Protection Act), you can request PMI cancellation once your loan principal reaches 80% of original value, and lenders must automatically cancel it at 78%.
