Example $400K loan: 30-year at 6.5% = $2,528/mo, 15-year at 5.75% = $3,307/mo.
How much do you save with a 15-year mortgage vs 30-year?
You save $80,000-$150,000 in total interest with a 15-year mortgage. Example on $400K loan: 30-year at 6.5% = $510,000 total interest paid. 15-year at 5.75% = $195,000 total interest paid. Savings = $315,000 total ($89,000 after accounting for higher monthly payments). BUT: 15-year costs $430-$780/month more, so you need stable income and cash flow.
Is a 15-year mortgage worth it?
A 15-year mortgage is worth it if: 1) You can comfortably afford $400-$600/month higher payment, 2) You have stable income and emergency fund (6+ months), 3) You plan to stay in home 7+ years, 4) You're 40+ years old (want to pay off before retirement), 5) You have no high-interest debt (credit cards 18%+). NOT worth it if: You're stretching budget, first-time buyer with tight cash flow, or need flexibility for kids/life changes.
What are the current rates for 30-year vs 15-year mortgages in 2026?
Current mortgage rates March 2026: 30-year fixed: 6.50% average (range 6.25-6.75%). 15-year fixed: 5.75% average (range 5.50-6.00%). Difference: 0.75% lower for 15-year. This 0.75% gap is typical - lenders reward shorter terms with lower rates because less risk. Your actual rate depends on credit score (740+ gets best rates), down payment (20%+ avoids PMI), and debt-to-income ratio (under 43% preferred).
Can I pay off a 30-year mortgage in 15 years?
YES, you can pay off a 30-year mortgage in 15 years by making extra principal payments. BUT you'll pay MORE interest than a true 15-year mortgage. Example $400K loan: 30-year at 6.5% paid off in 15 years = $230,000 total interest. True 15-year at 5.75% = $195,000 total interest. You lose $35,000 because of higher 30-year rate. BENEFIT of 30-year: Flexibility - you can reduce payments if needed. BENEFIT of 15-year: Forced discipline + lower rate.
What is the monthly payment difference between 30-year and 15-year mortgage?

Rule of thumb: 15-year payment is 30-35% higher than 30-year.
Should I get a 15-year or 30-year mortgage as a first-time buyer?
First-time buyers should usually choose 30-year mortgage because: 1) Lower monthly payment = easier to qualify and budget, 2) More cash flow for furniture, repairs, emergencies, 3) Flexibility if income changes or kids arrive, 4) Can always pay extra principal later when income grows.

After 10 years: 30-year: $112,000 equity (28%). 15-year: $327,000 equity (82%) - nearly paid off!
