- Calculate precise monthly payment savings
- Compute break-even holding period in months

## Mortgage Discount Points Explained

**Discount points** are upfront fees paid to a lender at closing to buy down the interest rate on a mortgage. One point costs 1% of the loan amount and typically lowers the interest rate by 0.25% (25 basis points).

Paying points is essentially pre-paying interest. The financial decision depends on whether you plan to hold the loan long enough for the monthly savings to exceed the upfront cost.

Let's define the math:

$$\text{Points Cost \$} = \text{Loan Amount} \times \frac{\text{Points Cost \%}}{100}$$

$$\text{Monthly Savings} = \text{Monthly Payment}_{\text{Base}} - \text{Monthly Payment}_{\text{Discount}}$$

$$\text{Break-Even Time (Months)} = \frac{\text{Points Cost \$}}{\text{Monthly Savings}}$$

If you plan to sell the home or refinance the mortgage before the break-even month, paying points is a net financial loss. If you hold the mortgage past the break-even timeline, you save money over the life of the loan.

## How to Use This Calculator

Enter your loan amount, the base (no-points) interest rate you were quoted, and the lower "bought-down" rate the lender offers if you pay points. Add the cost of those points as a percentage of the loan (1 point = 1%), and your estimated holding period — how long you expect to keep the mortgage before selling or refinancing.

The calculator computes both monthly payments on a 30-year amortization, the resulting monthly savings, the exact break-even month, and your net interest savings (or net loss) over your specified holding period after subtracting the upfront points cost.

## Worked Example: Buying Down a $300,000 Loan by 0.5%

A borrower is quoted 6.5% on a $300,000 loan, or 6.0% for 1 point (1% of the loan, or $3,000 upfront). The base monthly payment (P&I) is about $1,896; the discounted payment is about $1,799 — a monthly savings of roughly $97.55.

Dividing the $3,000 points cost by the $97.55 monthly savings gives a break-even of about 30.8 months, just under 2.6 years. If the borrower plans to hold the loan for 5 years, the gross interest saved over that period is about $7,523, and after subtracting the $3,000 upfront cost, the net lifetime savings is about $4,523 — meaning paying the point clears its break-even well within a typical 5-year holding period and nets a real savings.

## Frequently asked questions

### What are mortgage discount points?

Discount points are fees paid directly to a lender at closing to lower your mortgage interest rate. One point costs 1% of your loan amount.

### How much does one discount point lower the interest rate?

Typically, one point lowers the interest rate by 0.25% (25 basis points), though this depends on the lender, loan product, and market conditions.

### How do you calculate the break-even period for points?

Divide the upfront cost of the points by the monthly payment savings. For example, if points cost $3,000 and save you $50 a month, the break-even period is $3,000 / $50 = 60 months (5 years).

### Should I buy points if I plan to refinance soon?

No. If you refinance, you replace the loan with a new one, wiping out the lower rate you paid for. If you refinance before the break-even point, you will lose money on the upfront points cost.

### Are mortgage discount points tax-deductible?

Yes, on a primary residence, discount points are generally tax-deductible as mortgage interest in the year they are paid, subject to IRS limits. For investment properties, points must be amortized over the life of the loan.

### What is the difference between discount points and origination points?

Discount points are optional fees paid to lower your interest rate. Origination points are mandatory fees charged by the lender to cover the administrative costs of processing and underwriting the loan.

### Does paying points reduce my monthly principal payment?

No, paying points lowers the interest rate, which reduces the monthly interest portion. This lowers the total monthly payment and increases the rate at which you pay down the principal balance.

### Is it better to pay points or make a larger down payment?

It depends. A larger down payment increases your home equity and can help you avoid private mortgage insurance (PMI). Buying points lowers your monthly interest rate, which may save more money if you hold the loan long-term.

### Can the seller pay for my discount points?

Yes, sellers can pay for discount points as part of seller concessions, helping you secure a lower interest rate without paying cash out of pocket at closing.

### Do points make sense on a 15-year mortgage?

Generally less so than on a 30-year mortgage. Because a 15-year mortgage has a shorter term, the total interest paid is already lower, meaning you have less time to benefit from the interest rate reduction.
