Mortgage Points Guide: Discount Points and the Break-Even Test
Discount points vs. origination points, how to value a buydown, the break-even calculation, and when paying points actually pays off.
Two kinds of points
When mortgage materials say 'points,' they could mean one of two things. Discount points are an optional upfront fee you pay to lower your interest rate — buying down the rate. Origination points are the lender's fee for processing your loan, which is not optional and doesn't lower the rate. The fact that both are called 'points' creates persistent confusion.
Origination is usually expressed as a fee (often 0.5%–1% of the loan) or as a single number called a 'point' on the Loan Estimate. Discount points are separate line items. Read the LE carefully — the two are distinct.
How discount points work
One discount point is 1% of the loan amount, paid at closing. In exchange, the lender lowers your rate by approximately 0.25 percentage points. The exact rate reduction varies by lender, market conditions, and the size of the buydown.
On a $400,000 loan, one point costs $4,000 and might drop the rate from 7.0% to 6.75%. That cuts the monthly P&I from $2,661 to $2,594 — a savings of $67 per month. Two points (a $8,000 fee) might cut the rate to 6.50%, saving about $130/month vs. the 7.0% baseline.
The break-even calculation
Break-even months = Point cost ÷ Monthly payment savings
From the example above: $4,000 ÷ $67 = 60 months. You break even in five years. If you keep the loan past month 60, points pay; if you refinance, sell, or pay off before month 60, you lose money on the points.
Be honest about your hold period. The average first-time buyer keeps their home about 8 years and refinances their loan within 4–6 years on average. If you're statistically average, paying points is a 50/50 proposition at best.
When points make sense
Long hold horizon. If you plan to keep the home and the loan for at least 7–10 years, points usually pay.
Surplus closing cash. If you have extra cash and have already funded reserves, retirement, and any other higher-priority financial goals, points can be a reasonable use of cash for a long-hold buyer.
Tax benefit. Discount points on a primary residence are typically deductible in the year paid. Origination points are also deductible. Consult a tax professional for your specific situation.
When points don't make sense
Short hold or possible refinance. If you might sell or refinance within 5 years, the math usually fails.
Cash-constrained at closing. If paying points leaves you without adequate reserves, skip them. Reserves are insurance against a job loss, repair surprise, or other shock; points are a long-term optimization.
Higher-yielding alternative. If you have high-interest credit card debt, the same $4,000 paid against the cards usually saves more than the rate buydown.
Aggressive prepayment plan. If you're planning to send extra principal monthly to pay off the loan early, the points break-even shifts later because the loan ends sooner.
Negative points and lender credits
The flip side: you can take a higher rate in exchange for lender credits at closing. One negative point (a $4,000 lender credit on a $400,000 loan) might come with a rate 0.25% higher than par.
Negative points are useful when closing cash is tight. They're effectively a no-closing-cost loan — the lender pays your costs in exchange for a higher rate. Run the same break-even math: at what point does the cumulative extra interest exceed the upfront credit? For most borrowers that's also 5–7 years.
Comparing loans with different point structures
When comparing Loan Estimates, the APR column accounts for points and fees and re-expresses everything as an annualized rate. Two loans — one with no points at 7.0% and one with one point at 6.75% — might have similar APRs.
APR is the right comparison for ranking offers. But it assumes you keep the loan for the full term, which most borrowers don't. The break-even formula respects the reality that most loans pay off early.
Practical advice
Ask each lender to quote three options: par rate (no points and no credits), a one-point buydown, and a one-point lender credit. Calculate the break-even on each. Pick the option that matches your honest hold horizon, not the salesperson's optimistic horizon.
Use the payment calculator to model each option side by side. Toggle the rate and see the monthly payment impact. Then divide the upfront difference by the monthly savings — that's your number.
