Buying Points vs Down Payment: Which Saves More?

10 min read Updated August 2026 Mortgages, Interest Rates, Home Buying

The Core Rule

If you have extra cash at closing, buying mortgage discount points maximizes long-term interest savings if you are 100% certain you will keep the mortgage past the 5 to 7 year break-even point without refinancing. A larger down payment is superior if your time horizon is under 5 years, if the extra cash eliminates Private Mortgage Insurance (PMI), or if you want immediate built-in equity and lower risk.

Side-by-Side Comparison

Factor ($400k Home, $6,400 Extra Cash)	Option A: Buy 2 Discount Points	Option B: Increase Down Payment
Upfront Cash Deployed	$6,400 (Paid as prepaid interest)	$6,400 (Added to equity)
Loan Amount	$320,000 (80% LTV)	$313,600 (78.4% LTV)
Final Interest Rate	6.25% (0.50% rate discount)	6.75% (Standard note rate)
Monthly Payment (P&I)	$1,970.33/month	$2,033.93/month
Monthly Cash Savings	-$105.11/mo (vs baseline $2,075.44)	-$41.51/mo (vs baseline)
Break-Even Payback Period	60.8 Months (~5.1 Years)	Instant (100% converted to home equity)
Equity Created on Day 1	$0 (Fee paid to lender)	+$6,400 immediate equity
10-Year Cumulative Savings	$12,613.20 (Net +$6,213.20 profit)	$4,981.20 (Net +$4,981.20)

When to Choose Each Option

Buy Discount Points when…

You are buying a "forever home" and will keep the loan for 7+ years
Mortgage interest rates are historically average and unlikely to drop soon
You already have 20% down (so extra cash isn't needed to avoid PMI)
The seller or builder is offering closing cost credits to buy down your rate
You want to maximize total 30-year interest savings over decades

Increase Down Payment when…

You might move, sell, or refinance within the next 3 to 5 years
The extra cash pushes your down payment to 20%, eliminating PMI
Current mortgage rates are high and you anticipate refinancing in 1–3 years
You want immediate home equity to insulate against potential market drops
You want guaranteed equity recovery rather than betting on loan longevity

Methodology

Mortgage Points vs Bigger Down Payment: Where to Put Cash compares Discount Points and Bigger Down Payment using the figures you enter — including what it does, cost, typical break-even, can it eliminate pmi? — to show which option costs less, when each one is the better choice, and the break-even between them. The embedded calculators run your own numbers so the comparison reflects your situation, not a generic example.

Assumptions

All rates, balances, contributions, and timelines are user-supplied; defaults are illustrative round numbers, not quotes.
Regulatory figures cited (2026 IRS limits, tax brackets, and similar) reflect published federal values for the stated year.
Results assume the inputs hold over the chosen horizon and do not model every individual circumstance.

Limitations

This page does not predict future interest rates, returns, tax law, or prices, and is not a substitute for personalized professional advice.
Fees, credit-tier pricing, eligibility rules, and state-specific differences can materially change the outcome for your situation.

How Mortgage Discount Points & Buydowns Work

Mortgage discount points represent prepaid interest. In exchange for paying an upfront fee at closing, the lender permanently reduces the interest rate on your promissory note:

Discount Points Pricing Rules

1 Discount Point = 1.00% of Loan Amount Typical Rate Reduction = 0.25% (25 basis points) per point Break-Even Horizon (Months) = Upfront Points Cost / Monthly Payment Savings

For example, on a $320,000 loan, 1 point costs $3,200 and lowers your rate from 6.75% to 6.50%. Buying 2 points costs $6,400 and lowers the rate to 6.25%. Because the upfront fee is unrecoverable if you pay off the loan early, the viability of points depends strictly on holding duration.

Worked Numeric Modeling: $6,400 Extra Cash on $400k Home

Consider a buyer purchasing a $400,000 home with $80,000 base down payment (20%) at a 6.75% 30-year fixed rate who has $6,400 in surplus cash:

Baseline (No Points, 20% Down / $320,000 Loan at 6.75%):
• Monthly P&I: $2,075.44/month
• Total 30-Year Interest: $427,158.00
Option A — Buy 2 Discount Points ($6,400 Fee → 6.25% Rate on $320,000 Loan):
• New Monthly P&I: $1,970.33/month
• Monthly Savings: $2,075.44 − $1,970.33 = $105.11/month
• Break-Even Point: $6,400 / $105.11 = 60.8 Months (5.1 Years)
• Total 30-Year Interest: $389,320.00 (Direct Interest Savings: $37,838.00)
• Net 30-Year Profit After $6,400 Cost: $37,838 − $6,400 = +$31,438.00
Option B — Add $6,400 to Down Payment ($313,600 Loan at 6.75%):
• New Monthly P&I: $2,033.93/month
• Monthly Savings: $2,075.44 − $2,033.93 = $41.51/month
• Total 30-Year Interest: $418,615.00 (Direct Interest Savings: $8,543.00)
• Total Day 1 Equity: $86,400.00 (100% recovered upon resale)
The Decision Verdict:
• If you keep the mortgage for less than 5.1 years: Increasing the down payment wins (avoids forfeiting $6,400).
• If you keep the mortgage for more than 5.1 years: Buying points delivers 2.5× greater monthly cash flow savings ($105/mo vs $41/mo) and $31,438 in net profit.

Visualizing the Break-Even Horizon: Points vs. Down Payment

The visual below illustrates how cumulative cash savings cross over at the 5.1-year break-even threshold:

Cumulative Net Savings: Points vs. Down Payment ($6,400)

Tracking Net Cash Flow Benefit at Year 3, Year 5 (Break-Even), and Year 10.

Net Financial Position Over Time: 2 Points vs Larger Down Payment ($6,400)
Horizon	2 Points Net Cash Position	Larger Down Payment Net Position	Winning Strategy
Year 3 (36 Mos)	-$2,616.04 (Still in payback period)	+$1,494.36 (Plus $6.4k equity)	Larger Down Payment
Year 5.1 (61 Mos)	$0.00 (Break-even threshold)	+$2,532.11	Even Transition
Year 10 (120 Mos)	+$6,213.20 net profit	+$4,981.20	Points (+2.5x cash flow)
Year 30 (360 Mos)	+$31,438.00 net profit	+$8,543.00	Points (+$22.9k advantage)

Figure 1: Buying discount points requires 5.1 years to break even. After Year 5, points generate significantly higher compound savings than down payment reduction.

The 20% PMI Elimination Cliff

There is one scenario where increasing the down payment always beats buying points: when the extra capital pushes your total down payment from 18%–19% to exactly 20% (80% LTV).

Buying points on an 18% down loan lowers your rate by 0.25% ($50/mo), but leaves you paying $150/mo in PMI.
Deploying that same cash to reach 20% down eliminates PMI entirely, creating an immediate +$150/month cash flow savings on Day 1 with zero break-even risk.

5 Critical Mistakes When Buying Points

Buying Points in a Peaking Rate Environment: Paying $5,000 for discount points right before mortgage rates drop across the economy. When you refinance 18 months later, your prepaid points are wiped out.
Ignoring Seller Concessions: Failing to ask the seller or builder to pay for discount points (permanent or temporary 2-1 buydowns) as part of purchase negotiations.
Assuming All Lenders Offer the Same Point Discounts: Rate reduction per point varies by lender and rate sheet. Always compare quotes across multiple lenders.
Confusing Discount Points with Origination Points: Origination points are administrative lender fees that do NOT reduce your interest rate. Only discount points lower your note rate.
Depleting Emergency Reserves: Spending liquid cash to buy down an interest rate while leaving zero savings for moving costs, furnishings, or emergency repairs.

Frequently Asked Questions

What is the break-even horizon on mortgage discount points?

The break-even point is calculated by dividing the total upfront cost of the discount points by the monthly payment savings. For most conventional mortgages, break-even occurs between 5 and 7 years (60 to 84 months). If you sell, move, or refinance before reaching break-even, buying points results in a net financial loss.

How much does 1 discount point reduce my mortgage rate?

1 mortgage point costs 1% of your total loan amount (e.g. $3,200 on a $320,000 loan) and typically lowers your interest rate by 0.25% (25 basis points). The exact reduction depends on current secondary mortgage market conditions and lender rate sheets.

Are mortgage discount points tax deductible?

Yes. On a primary home purchase, mortgage discount points are generally fully deductible in the year paid if you itemize deductions on IRS Schedule A (IRS Publication 936). On a refinance, discount points must be amortized and deducted evenly over the life of the loan.

Can putting more down eliminate PMI while buying points cannot?

Yes. If an extra down payment pushes your equity to 20% (80% LTV), it completely eliminates private mortgage insurance (saving $100–$200+/month). Buying points lowers the interest rate but has zero effect on your LTV ratio or PMI requirement.

What happens to paid discount points if I refinance early?

The upfront money paid for discount points is non-refundable. If you pay $6,400 for 2 points and refinance 2 years later when market rates drop, you forfeit the remaining unrecouped cost.
