Rate Buydown Calculator
Compare temporary buydowns (2-1, 3-2-1) and permanent discount points side-by-side. See the year-by-year payment schedule, true break-even, and a verdict that doesn’t pretend every buydown is a deal.
Year-by-Year Schedule
For temp buydowns, see the exact monthly payment in year 1, year 2, year 3, and full-rate. No surprises when the buydown ends.
Temp vs Permanent
Switch tabs to compare a 2-1 or 3-2-1 buydown against paying real discount points for a permanent rate cut. Different math, different audiences.
Break-Even That’s Honest
Points only pay off if you keep the loan past break-even. We compare break-even months to your actual horizon and tell you if it pencils.

If you’ll keep the loan past break-even, points generally pay off. If not, keep your cash.
Temporary vs Permanent: How They Actually Differ
Both buydowns lower your payment, but they’re built for different situations.
Temporary buydowns (2-1, 3-2-1) reduce your interest rate for the first 1-3 years, then snap back to the full note rate for the rest of the loan. The cost is paid up front into an escrow account and applied as a monthly subsidy. Almost always paid by the seller, builder, or lender as a concession – rarely a smart move with your own money. They’re popular when sellers want to move a property without dropping the list price.
Permanent buydowns (discount points) permanently lower your interest rate for the entire loan. You pay 1% of the loan amount per point, and each point typically buys down the rate by about 0.25% – though that ratio varies by lender, loan type, and market. Points pay off only if you keep the loan past break-even. If you refi or sell before then, you lose money.
When a Temporary Buydown Actually Helps
- Seller is paying the concession. A 2-1 buydown can run 2-3% of loan amount. If a seller is offering it instead of a price cut, you get free monthly cash-flow relief in years 1-2 with no out-of-pocket cost. That’s a yes.
- You expect income to grow. Newer professional, residency-to-attending, or income ramping up with the business – lower payments early, full payments once you can absorb them.
- You expect to refi within 1-2 years. If rates drop and you refinance during the buydown period, any unused subsidy is typically credited toward your refinance closing costs. You don’t lose what wasn’t used.
- Builder incentive on a new construction. Many Florida builders are offering 2-1 buydowns as a sweetener instead of dropping list prices. Worth taking if it’s already on the table.
When Discount Points Pay Off
- You’re keeping the loan a long time. Points pay off if you stay past break-even. On a 30-year loan you actually keep for 15+ years, even small rate cuts add up to real money.
- You have cash to spare without draining reserves. Points come out of cash to close. Don’t pay points if it leaves you under 2-3 months of reserves after closing.
- Rates are unlikely to drop meaningfully. If you’re convinced rates will fall and you’ll refi within a few years, paying points is paying for a benefit you won’t collect.
- The lender is offering a strong points-to-rate ratio. Standard is roughly 1 point for 0.25% rate cut. Some lenders offer better; some worse. Always compare the no-point rate to the bought-down rate before deciding.
What This Calculator Doesn’t Cover
- Lender-paid temporary buydowns vs higher rate. Some lenders offer to fund the buydown themselves in exchange for a slightly higher note rate. Worth a side-by-side – call us and we’ll run it.
- Points on government loans. FHA, VA, and USDA loans treat points slightly differently for qualification and cash-to-close. The math here is the same; the structure isn’t.
- Tax deductibility. Discount points on a primary residence purchase are generally deductible the year paid. Refinance points must be amortized. Consult a tax pro – that’s not me.
- Negotiation leverage. A seller offering a 3% concession may be more flexible on price than the listing suggests. Sometimes the buydown is the wrong ask.
