When you apply for a mortgage in California, one of the first decisions you’ll make is loan term: 15 years or 30 years. It’s one of the most common comparison searches — and the right answer depends entirely on your financial situation, not a blanket rule.
The Core Difference: Payment vs. Total Cost
A 30-year mortgage spreads your payments over 360 months, giving you a lower monthly payment. A 15-year mortgage doubles the pace — you own the home free and clear in half the time, but your payment is significantly higher. In exchange for that bigger payment, you get a lower interest rate and pay dramatically less in total interest.
Real Numbers: $700,000 California Home (2026)
Assuming a $700,000 loan at current rates (approximate as of mid-2026):
| 30-Year Fixed | 15-Year Fixed | |
|---|---|---|
| Rate (approx.) | 6.75% | 6.00% |
| Monthly Payment (P&I) | $4,541 | $5,909 |
| Total Interest Paid | $935,700 | $363,700 |
| Interest Savings | — | $572,000 |
| Monthly Difference | — | +$1,368/mo |
That’s over half a million dollars in interest saved with a 15-year loan — but you’re paying nearly $1,400 more every month to get there.
The Case for a 30-Year Mortgage
The 30-year is far and away the most popular mortgage in California — and for good reason at California prices:
- Lower payment preserves cash flow for investing, savings, and life expenses
- Flexibility — you can make extra principal payments anytime to pay it off faster without being locked into the higher payment
- Qualification is easier — lower DTI means you qualify for more home
- In high-cost markets, a 15-year payment on a $900,000 loan may simply be unaffordable
The Case for a 15-Year Mortgage
- Lower interest rate — typically 0.5–0.75% below 30-year rates
- Build equity twice as fast — critical if you’re close to retirement
- Massive interest savings — often $300,000–$600,000 over the life of the loan
- Forced savings discipline — you’re building wealth automatically
The Middle Path: 30-Year Loan + Extra Payments
Many California buyers take a 30-year loan and make extra principal payments each month. This gives you the interest savings of a shorter term while preserving the flexibility to drop back to the minimum payment if cash flow gets tight. Some people round up to the nearest $500; others make one extra payment per year.
If you add $500/month extra to that $700,000 loan example above, you’d pay it off in roughly 22 years and save about $250,000 in interest — without the rigidity of a 15-year commitment.
Which Should You Choose?
Go with a 15-year if you can comfortably afford the payment (keeping your total housing costs under 28–30% of gross income), you’re within 15 years of retirement, or you’re buying a less expensive property.
Go with a 30-year if you’re buying in a high-cost California market, your cash flow is tighter, you want flexibility, or you plan to invest the monthly difference in the market.
Frequently Asked Questions
Is a 15-year or 30-year mortgage better in California?
It depends entirely on your financial situation. A 15-year mortgage saves hundreds of thousands in interest and builds equity faster, but the monthly payment is significantly higher. A 30-year is more flexible and easier to qualify for — critical in California’s high-cost markets. Many buyers choose a 30-year loan and make extra principal payments to get the best of both worlds.
How much do you save with a 15-year vs 30-year mortgage?
On a $700,000 loan, a 15-year mortgage can save approximately $572,000 in total interest compared to a 30-year loan (based on approximate mid-2026 rates of 6.00% vs. 6.75%). The savings are substantial, but the monthly payment is about $1,368 higher — so the math has to work with your income and monthly budget.
Can I pay off a 30-year mortgage in 15 years by making extra payments?
Yes — making extra principal payments on a 30-year mortgage can dramatically shorten the payoff timeline and reduce total interest. The advantage is flexibility: if cash flow gets tight, you can return to the minimum payment. Adding $500/month to a $700,000 loan could pay it off in about 22 years and save roughly $250,000 in interest.
What is the interest rate difference between 15 and 30-year mortgages?
Typically, 15-year mortgage rates run 0.50–0.75% lower than 30-year rates. This rate difference, combined with the shorter term, is what drives the massive interest savings on a 15-year loan. The exact spread varies by lender, credit score, and market conditions — call me for current rate comparisons on both terms.
