how much does it cost to buy down interest rate

June 27, 2026

It usually costs about 0.25%–1% of your loan amount in upfront “points” for each 0.25% you lower your mortgage interest rate , but the exact price is set by the lender and current market conditions.

What “buying down an interest rate” means

When you buy down your rate, you pay extra cash at closing (called discount points) to get a lower interest rate for your mortgage.

1 point = 1% of your loan amount.
- On a 300,000 loan, 1 point costs 3,000.

Each point typically lowers your rate by about 0.25% , though this can vary by lender and loan program.

Lenders often limit how many points you can buy, and consumer-protection rules cap how many fees/points can be charged.

In simple terms: You trade more cash today for lower monthly payments over time.

Typical cost ranges (with examples)

Because lenders and markets differ, you’ll see ranges rather than one fixed price.

Common pattern lenders advertise:

1 point (1% of loan) → about 0.25% rate reduction
To reduce your rate by 1% , you may need 3–4 points in many real‑world scenarios.

Example: 200,000 loan

Approximate illustrative numbers:

Buy down 0.25% →
- Cost: 0.25%–1% of 200,000 = 500–2,000 upfront.
Buy down 0.50% →
- Cost: often around 2 points , roughly 4,000.
Buy down 1.00% →
- Cost: often around 4 points , roughly 8,000 (some guides show 12,000 on a 300,000 loan).

Example: 400,000 loan

1 point (1%) costs 4,000.
That might cut your rate from 7.00% to about 6.75% for the life of the loan.

Dropping the rate a full 1% might require 12,000–16,000 at closing (3–4 points) depending on the lender and pricing.

Permanent vs. temporary buydowns

There are two big flavors of buydowns that affect what you “get” for that cost.

Permanent buydown
- You pay points once.
- Your rate is lower for the entire life of the loan (e.g., 30 years).

* Typically more expensive upfront, but bigger total interest savings over time.

Temporary buydown (e.g., 2-1 or 3-2-1)
- Someone (you, the seller, or builder) prepays interest so your rate is reduced only for the first 1–3 years.

* Cheaper than a permanent buydown, but your rate eventually steps back up to the standard note rate.

Because the cost structure is different, you’ll see that permanent buydowns often have higher total cost but much larger lifetime interest savings, while temporary buydowns are used to ease payment “sticker shock” in the early years.

How to know if it’s “worth it”: the breakeven test

Most mortgage pros will tell you to run a breakeven analysis before paying for points.

Find total cost of points.
- Example: 2 points on a 300,000 loan = 6,000.

Calculate your new monthly payment with the lower rate.
Monthly savings = old payment − new payment.
Breakeven months = total cost ÷ monthly savings.

If you plan to keep the home and mortgage longer than the breakeven period , buying down the rate often makes more sense. If you will sell or refinance sooner , the cash might be better used for:

A larger down payment (smaller loan, less interest).
Closing cost cushion or emergency savings.
Paying off higher‑interest debt first.

What forums and real buyers say

Real‑world forum discussions echo the same themes:

Nobody can quote your exact cost without seeing your exact scenario (credit, loan type, down payment, and today’s rate sheet).

A common rule of thumb:
- Each point shaves ~0.25% off the rate , and lenders typically cap how many points you can buy (often around 4–6 points or within legal fee caps).

Many buyers compare:
- “Put 9,000 into points” vs. “put 9,000 into a bigger down payment” and see which option gives better monthly and long‑term benefit.

Mini “story” to visualize it

Imagine Alex is buying a home with a 400,000 30‑year fixed mortgage at 7.00%. Alex can either:

Pay 0 points : keep the 7.00% rate, higher monthly payment, no extra cash due at closing.
Pay 3 points (12,000) : drop to roughly 6.00%, cutting the monthly payment and saving tens of thousands in interest over 30 years.

If the lower payment saves Alex about 200 per month, it takes roughly 60 months (5 years) to breakeven on the 12,000 spent. If Alex plans to stay 10+ years, the buydown may be worth it; if Alex expects to move in 3 years, it probably is not.

Key takeaways for “how much does it cost to buy down interest rate”

Expect to pay roughly 0.25%–1% of your loan per 0.25% rate reduction , but this is just a ballpark.

1 discount point = 1% of the loan , commonly lowering the rate by about 0.25%.

You may need 3–4 points to cut the rate a full 1%, costing thousands to tens of thousands depending on your loan size.

Always run the breakeven math and consider how long you’ll keep the loan.

For an exact dollar amount in your case, you’ll need a live quote from a lender, since pricing changes daily and varies across loan programs and credit profiles.
