Cumulative savings over time

This calculator assumes points provide a fixed rate reduction. Actual rates depend on lender offers and market conditions.

What are mortgage points?

Mortgage points (also called discount points) are upfront fees you pay to your lender in exchange for a lower interest rate on your home loan. Each point typically costs 1% of your total loan amount and reduces your interest rate by approximately 0.25%, though this can vary by lender and market conditions.

Think of points as prepaid interest. You're essentially paying some of your interest upfront in one lump sum rather than spreading it across your monthly payments over the life of the loan. This trade-off can save you significant money over time—but only if you keep the mortgage long enough to recoup the initial cost.

The decision to buy points is fundamentally a time-value-of-money calculation. You're paying money now to save money later, which means you need to weigh your current cash needs against your expected savings and consider how long you'll actually keep the loan before selling or refinancing.

How points work

PointsCost on $300,000 loanTypical rate reduction
0$0Base rate
1$3,0000.25% lower
2$6,0000.50% lower
3$9,0000.75% lower

The exact rate reduction varies by lender and market conditions. Some lenders offer more aggressive discounts during competitive periods, while others may provide smaller reductions when rates are already low. It's important to get quotes from multiple lenders to compare both the cost of points and the rate reduction you'll receive.

Points are paid at closing along with your other closing costs. They'll appear on your Loan Estimate and Closing Disclosure documents, so you can see exactly what you're paying and what rate reduction you're getting in return.

The break-even calculation

The break-even point is the most critical number when deciding whether to buy points. It tells you how many months of payments you need to make before your accumulated monthly savings equal the upfront cost of the points.

Break-even months=Cost of pointsMonthly savings\text{Break-even months} = \frac{\text{Cost of points}}{\text{Monthly savings}}

Example

  • Loan: $320,000
  • Points cost: $6,400 (2 points)
  • Monthly savings: $89
  • Break-even: 72 months (6 years)

In this example, if you keep the loan longer than 6 years, you come out ahead—every month after break-even puts money back in your pocket. But if you sell or refinance before reaching 6 years, you've lost money because you paid more upfront than you saved in lower payments.

This calculation assumes you don't invest the money elsewhere. If you could earn a higher return by investing the points cost in the stock market or paying down other debt, that changes the math. A more sophisticated analysis would compare the guaranteed return from points (your interest rate reduction) against your expected return from alternative investments.

When buying points makes sense

Points are typically worth it when you have a long time horizon and stability in your housing plans. The ideal candidate for buying points is someone who plans to stay in their home for many years, has no plans to refinance, and has sufficient cash reserves beyond what's needed for the down payment and emergency fund.

Consider buying points when:

  • You plan to stay in the home 7+ years (beyond break-even)
  • You're confident interest rates won't drop significantly (which would prompt refinancing)
  • You have excess cash that isn't needed for other purposes
  • You prefer the certainty of lower monthly payments
  • You're in a high tax bracket and can deduct the points
  • You're buying your "forever home" and expect to pay off the mortgage

Points also make more sense when interest rates are high. A 0.25% reduction matters more when rates are 7% than when they're 4%—both in absolute dollar terms and psychologically as a percentage of your rate.

When to skip points

Buying points is essentially a bet that you'll keep the mortgage long enough to break even. If there's significant uncertainty about your timeline, it's usually better to skip points and keep your cash.

Avoid buying points when:

  • You may move within 5-7 years for career or lifestyle reasons
  • You're likely to refinance if rates drop significantly
  • You need the cash for your down payment, closing costs, or emergency fund
  • You could get a better return investing the money elsewhere
  • You're getting an adjustable-rate mortgage (the rate will change anyway)
  • You're buying a starter home and expect to upgrade
  • You're uncertain about your job stability or location

Many first-time homebuyers are better off skipping points. They often underestimate how soon they'll want to move (growing family, job change, neighborhood preferences) and end up selling before reaching break-even.

Points vs. larger down payment

Before buying points, consider whether that money could be better used elsewhere. The same cash could increase your down payment, which has its own benefits.

OptionBenefits
Buy pointsLower rate, lower monthly payment, potential tax deduction
Larger down paymentLower loan amount, no PMI at 20%, less total interest, instant equity
Keep as savingsEmergency fund, investment returns, financial flexibility

A larger down payment reduces your loan principal, which means less interest over the life of the loan and lower monthly payments (though through a different mechanism). If you're close to the 20% threshold, putting extra cash toward the down payment eliminates private mortgage insurance (PMI), which can save you hundreds per month.

On the other hand, points provide a guaranteed return equal to your interest rate savings, while investments carry risk. If certainty and cash flow matter most to you, points might be the better choice despite potentially lower total returns.

Tax implications

Mortgage points may be tax-deductible, which effectively reduces their cost. However, the rules are specific about when and how you can take the deduction.

  • On a purchase: Points are often fully deductible in the year paid if the loan is for your primary residence and the points are a customary amount for your area
  • On a refinance: Points must typically be deducted ratably over the life of the loan (e.g., 1/30th per year for a 30-year loan)
  • Points paid by seller: If the seller pays points on your behalf, you can usually still deduct them

The deduction reduces your taxable income, not your tax bill directly. If you're in the 24% tax bracket and pay $3,000 in points, you'd save about $720 in taxes ($3,000 × 24%). This effective discount should be factored into your break-even calculation.

However, the Tax Cuts and Jobs Act of 2017 significantly increased the standard deduction, meaning fewer homeowners itemize. If you take the standard deduction, you won't receive any tax benefit from points. Consult a tax professional for your specific situation.

Origination points vs. discount points

Not all points are created equal. It's crucial to understand the difference between discount points and origination points, as they serve completely different purposes.

TypePurposeTax deductible
Discount pointsBuy down interest rateYes (if itemizing)
Origination pointsLender's processing feeSometimes

Discount points are what we've been discussing—fees you pay voluntarily to reduce your rate. Origination points (or origination fees) are what the lender charges to process your loan. Origination points don't reduce your rate; they're simply a cost of getting the loan.

Some lenders roll all their fees into "points" without distinguishing between the two types. When comparing loan offers, make sure you understand what you're actually paying for. A lender charging 1 point with a 6.5% rate isn't necessarily worse than one charging 0 points at 6.75%—but it is worse than a lender charging 0 points at 6.5%.

Negotiating points

The cost of points and the rate reduction they provide aren't fixed—they're negotiable and vary significantly between lenders. A little shopping can save you thousands.

Tips for getting the best deal:

  1. Compare multiple lenders: Get quotes from at least 3-4 lenders, including banks, credit unions, and online lenders. Ask each for pricing with 0, 1, and 2 points to see who offers the best value.

  2. Ask for detailed breakdowns: Request itemized quotes showing exactly what rate reduction each point buys. Some lenders offer better deals on the first point than subsequent ones.

  3. Negotiate the base rate first: Start by negotiating the no-points rate, then evaluate whether points are worth it. A lender with a higher base rate but "better" points might not actually be competitive.

  4. Time your rate lock: Point costs can fluctuate with market conditions. If rates are volatile, ask about float-down options that let you benefit if rates drop before closing.

  5. Consider lender credits: If points don't make sense for you, see if the lender will give you credits (the opposite of points) to reduce closing costs.

Lender credits (negative points)

Lender credits are the inverse of discount points. Instead of paying upfront for a lower rate, you accept a higher rate in exchange for cash toward your closing costs. This can be valuable if you're short on cash or don't plan to keep the loan long.

CreditsRate impactBest for
-1 point+0.25% rateShort-term owners, cash-strapped buyers
-2 points+0.50% rateThose who plan to refinance soon

Lender credits make sense when your break-even calculation works in reverse. If accepting a 0.25% higher rate costs you $50/month extra, and you receive $3,000 in credits, you break even in 60 months. If you sell or refinance before then, you come out ahead.

This strategy is particularly useful when you expect to refinance—perhaps because you're buying when rates are high and expect them to fall, or because you plan to significantly improve your credit score and qualify for better rates later.

How points affect APR

Annual Percentage Rate (APR) is designed to help you compare the true cost of loans by factoring in points and certain fees. However, it's not a perfect comparison tool.

  • A loan with points will have a lower nominal rate but may have a higher APR
  • APR assumes you keep the loan for its full term, which overstates the cost of points for long-term owners
  • Compare both rate and APR, and run your own break-even calculations

For example, a 6.5% loan with 2 points might show a 6.65% APR, while a 6.75% loan with 0 points shows a 6.80% APR. The APR suggests the first loan is cheaper, but only if you keep it long enough. If you refinance in year 3, the second loan was actually the better deal.

Points and refinancing

Refinancing resets your break-even calculation to zero. All those months of savings you accumulated toward paying off your original points? They're locked in, but your new loan starts fresh.

When calculating if points are worth it, consider:

  • Current rate trends: If rates are historically high, you're likely to refinance when they drop, making points a poor investment
  • Your refinancing history: If you've refinanced multiple times before, you'll probably do it again
  • Life changes: Expect any major changes (kids, retirement, job relocation) that might prompt moving or refinancing?

As a rule of thumb, if there's more than a 50% chance you'll refinance within your break-even period, skip the points. The guaranteed loss from paying for points you don't fully use outweighs the potential savings.

Fractional points

You don't have to buy whole points. Most lenders let you purchase fractional amounts like 0.5 points or 0.75 points. This gives you more flexibility to fine-tune your upfront costs and monthly payment.

Fractional points can help you:

  • Hit a specific monthly payment target
  • Use up remaining cash after down payment and reserves
  • Find your optimal break-even point

If your break-even analysis shows that 2 points pays off in 8 years but you only plan to stay 6 years, buying 1 or 1.5 points might hit the sweet spot where you still break even within your timeline.

Common mistakes

  1. Ignoring break-even: The most common mistake is buying points without calculating how long it takes to recoup the cost. Always run the numbers before deciding.

  2. Over-buying points: More points isn't always better. The rate reduction often diminishes after the first 1-2 points, and you tie up more cash with longer break-even periods.

  3. Ignoring alternatives: Not comparing points to alternatives like a larger down payment or keeping the cash invested.

  4. Forgetting taxes: Not factoring in the tax deductibility of points, which can significantly improve your effective return (if you itemize).

  5. Optimistic timelines: Assuming you'll stay in the home longer than you actually will. Life changes—jobs, families, preferences—often prompt moves sooner than expected.

  6. Ignoring opportunity cost: The money spent on points could be invested elsewhere. A 6% guaranteed return from points is good, but not if you could earn 10% in the market.

  7. Not shopping around: Accepting your first lender's point pricing without comparing. The difference between lenders can be substantial.

The bottom line

Mortgage points are a financial tool, not inherently good or bad. They work well for long-term, stable homeowners who have extra cash and want predictable savings. They work poorly for people with uncertain timelines, limited cash reserves, or expectations that they'll refinance.

Run the break-even calculation, consider your realistic timeline, factor in taxes and opportunity costs, and compare multiple lenders. With those inputs, the right decision usually becomes clear.
