Mortgage Points Explained: Should You Buy Down Your Rate?

How Mortgage Points Work

When you close on a mortgage, the lender may offer you a choice: pay a higher rate now with no upfront cost, or pay discount points at closing to permanently lower your rate. Each point costs 1% of the loan amount and reduces the rate — the exact reduction varies by lender and market conditions, but 0.25% per point is a common benchmark.

Discount Points vs Origination Points

Discount points are what most people mean when they say "mortgage points." They are optional — you choose to pay them upfront to buy a lower rate. They are sometimes tax-deductible.

Origination points are a lender fee for processing the loan — essentially a different way of charging for their service. They don't reduce your rate. Always check your Loan Estimate carefully to understand which type of points you're being charged and what each one does.

The CFPB's standardised Loan Estimate form (which all lenders must provide within 3 business days of your application) clearly identifies discount points vs origination charges — use it to compare lenders apples-to-apples.

The Break-Even Calculation

This is the only number that truly matters when deciding whether to buy points:

Break-even months = Cost of points ÷ Monthly payment savings

Using the example above — 1 point costs $3,500 and saves $57/month:

$3,500 ÷ $57 = 61 months (about 5 years)

If you stay in the home beyond 5 years, buying 1 point pays off. If you move or refinance before 5 years, you've lost money on the points.

When Buying Points Makes Sense

You're buying a forever home. If you plan to live there for 10–20+ years, the long-term rate reduction is extremely valuable. Points bought on a 30-year loan that you hold for 25 years produce enormous cumulative savings.

Rates are elevated and unlikely to fall soon. If you buy points when rates are high and then rates drop, you'll refinance anyway — losing the value of the points paid. But if rates are expected to stay flat or rise, locking in a lower rate via points is more valuable.

You have cash to spare after the down payment and reserves. Points only make sense if you have sufficient liquid savings after paying them. Depleting reserves to buy points creates financial risk.

The monthly savings meaningfully improve your budget. If reducing the rate by 0.5% brings your monthly payment below a threshold that makes the budget significantly more comfortable, the psychological and practical value can justify the upfront cost even before the break-even point.

When Points Are Not Worth It

You plan to sell or move within 5–7 years. Most break-even periods fall in this range. If there's a reasonable chance you'll move before then, don't buy points.

Rates are likely to fall and you'd refinance. In an environment where the Federal Reserve is expected to cut rates, buying points today and then refinancing in 2 years forfeits the upfront cost entirely.

You need the cash for reserves or other goals. $7,000 in points buys you $113/month in savings (break-even ~62 months). That same $7,000 in an index fund at historical returns grows meaningfully over 5 years. Points aren't automatically the best use of excess closing cash.

Tax Treatment

Discount points paid when buying or building a primary residence are generally deductible in the year paid if they meet IRS requirements — including that the points are a standard practice in your area, they aren't paid in lieu of other closing costs, and the loan is secured by your main home.

Points paid on a refinance must be deducted over the life of the loan (amortised), not all in year one — unless the refinance cash-out portion was used for home improvements. Given the complexity, consult a CPA or tax advisor if you're counting on the deduction. Source: IRS Topic 504.

Rate Buydowns in the UK, India, and Canada

UK: The concept of buying down your interest rate via upfront points doesn't directly translate to the UK market. UK mortgages are typically quoted as a complete package — the rate, arrangement fee, and terms are bundled. Arrangement fees (typically £999–£2,000) sometimes produce lower rates, which is functionally similar to paying points. A mortgage broker can model whether a low-fee/higher-rate or high-fee/lower-rate deal is cheaper for your expected holding period. Check MoneyHelper at moneyhelper.org.uk.

India: Indian home loans don't use a points system, but some banks offer processing fee waivers or reduced rates for customers meeting certain profiles (high credit score, large down payment, existing relationship with the bank). Prepayment of a lump sum early in the loan can achieve a similar economic effect to buying points — reducing the outstanding balance reduces both future interest and total loan cost. RBI guidelines at rbi.org.in.

Canada: Like the UK, Canadian mortgages don't use a points system as standard. Lenders quote a rate with associated terms. Some lenders offer rate reductions in exchange for restrictions (e.g., larger prepayment penalties or limitations on portability). A mortgage broker comparison across lenders achieves the same result — finding the best rate for your specific term and amortisation. CMHC at cmhc-schl.gc.ca.
