What Are Mortgage Points?

Mortgage points, also called discount points, are optional fees you pay to your lender at closing to reduce your interest rate. Each point typically costs 1% of your loan amount and usually reduces your rate by about 0.25%. For example, on a $300,000 loan, one point costs $3,000 and might lower your rate from 6.5% to 6.25%. This is essentially prepaying interest to secure a lower rate for the life of your loan.

The concept is straightforward: pay more upfront to save money over time through lower monthly payments and reduced total interest. However, whether this makes financial sense depends on multiple factors including how long you plan to keep the mortgage, your available cash at closing, alternative investment opportunities, and the specific rate reduction offered by your lender.

How Points Affect Your Mortgage

Upfront Cost: Points are paid at closing and increase your initial cash requirement. On a $300,000 loan, two points cost $6,000 upfront. This money comes from your down payment savings or closing cost funds, potentially requiring you to save longer or borrow more for your home purchase.

Monthly Savings: The reduced interest rate lowers your monthly principal and interest payment. A 0.5% rate reduction on a $300,000 30-year loan saves approximately $90 per month. While this seems modest monthly, it compounds significantly over the loan term.

Long-Term Interest: Over the full loan term, the total interest savings can be substantial. That same 0.5% reduction could save $30,000+ in interest over 30 years. However, most homeowners refinance or sell before loan maturity, making the break-even point crucial.

Calculating Your Break-Even Point

The break-even point is when your cumulative monthly savings equal the upfront cost of points. For example, if points cost $6,000 and you save $90 monthly, you break even in 67 months (5.6 years). If you plan to keep the mortgage longer than the break-even period, points likely make financial sense. If you plan to refinance or sell sooner, you'll lose money on the points purchase.

Break-even calculations become more complex when considering opportunity cost - what else could you do with that upfront money? If you could invest it and earn higher returns than your mortgage interest savings, foregoing points might be better financially even if you keep the mortgage past break-even.

When Buying Points Makes Sense

• You plan to keep the mortgage well beyond the break-even point (typically 5-7+ years)
• You have sufficient cash reserves after covering down payment, closing costs, and emergency funds
• You're buying in a high-rate environment where rate reductions have greater impact
• Your monthly cash flow is tight and you need to lower the payment
• You're near a qualifying threshold for debt-to-income ratios
• Tax deductions for points apply to your situation (consult your tax advisor)
• Alternative investments would return less than your effective interest savings

When Points Don't Make Sense

• You plan to refinance within the next few years (rising equity or falling rates)
• You expect to relocate or sell the home before reaching break-even
• You're stretching financially to cover the down payment and closing costs
• You could invest the money in higher-returning opportunities
• You're buying in a declining rate environment where refinancing is likely
• The rate reduction offered per point is below market average (less than 0.25%)
• You prefer maintaining maximum liquidity for emergencies or opportunities

Points vs. Larger Down Payment

When deciding between buying points or making a larger down payment, consider that a larger down payment reduces your loan balance (saving interest across the entire amount) and may help you avoid PMI if you reach 20% equity. Points only reduce your interest rate. Run the numbers both ways - often a larger down payment provides better long-term value, especially if it eliminates mortgage insurance.

Tax Implications

Mortgage points paid on a primary residence purchase may be tax-deductible in the year paid, subject to IRS rules and limitations. Points paid on refinances must generally be deducted over the loan's life. With the higher standard deduction in recent tax law, fewer taxpayers itemize deductions, reducing the tax benefit of points. Consult a tax professional to understand your specific situation.
