Understanding Mortgage Amortization
Smart Mortgage Strategies That Save Thousands
Biweekly Payments
Pay half your monthly payment every 2 weeks. This equals 13 monthly payments per year instead of 12, shaving 4-6 years off a 30-year mortgage.
Put 20% Down
Avoid PMI entirely by putting 20% down. On a $350,000 home, PMI at 1% costs $2,917/year — money that could go toward principal.
Choose 15-Year If Affordable
A 15-year mortgage typically has a rate 0.5-0.75% lower and saves 60%+ in total interest compared to a 30-year term.
Buy Mortgage Points Wisely
Points make sense if you will stay in the home past the break-even period. Use our points calculator to check.
Refinance When Rates Drop 0.5%+
Even a 0.5% rate reduction can save thousands. Calculate the break-even point to confirm it is worth the closing costs.
15-Year vs 30-Year Mortgage Compared
Monthly Payment
30-year payments are typically 25-30% lower than 15-year for the same loan amount, providing more monthly cash flow.
Total Interest
A 15-year mortgage can save 50-65% in total interest compared to a 30-year, often amounting to $100K+ savings.
Interest Rate
15-year rates are typically 0.5-0.75% lower than 30-year rates, compounding the interest savings.
Equity Building
15-year builds equity much faster — you own 50% of the home in about 10 years vs. 25+ years on a 30-year.
Flexibility
30-year gives flexibility: you can make extra payments when possible without the obligation of a higher minimum.
