A mortgage points calculator for buydown conversations

When sellers offer concessions, one of the most effective uses can be buying down the buyer's rate. This mortgage points calculator shows what discount points cost, how much they lower the payment and the break-even month. It's useful when you're advising a buyer on how to use a seller credit, and when you're showing a seller how a concession can bring buyers back to a listing that's stalled.

Are mortgage points worth it?

They're worth it if the buyer keeps the loan longer than the break-even point, the month when cumulative payment savings exceed the cost of the points. If they're likely to sell or refinance sooner, points cost more than they save. When the seller pays for the points, the math is different, because the buyer isn't paying the cost.

When to put the Mortgage Points Calculator in front of people

On a listing that needs a price adjustment

Instead of a price cut, some sellers offer a credit toward a rate buydown. Put this calculator on the listing to show buyers the lower payment the credit could buy, which often matters to them more than a lower price.

When writing an offer with a seller credit

Run the numbers with your buyer: the credit could cover closing costs or buy down the rate. The calculator shows the monthly saving and break-even, so the buyer can decide with their lender.

In new-construction conversations

Builders often advertise rate buydowns. A points calculator helps buyers compare a buydown with a price reduction in terms they understand.

What your visitor sees

The buyer enters the loan amount, rate, term, number of discount points and the rate cut per point. They see the monthly saving, the cost of the points, the payment with and without points, the break-even month, the rate with points and the net savings over the full term.

The lead you receive

A buyer weighing a buydown, often near an offer

The lead includes the Loan Amount, Discount Points, Cost of Points, Monthly Saving, Break-Even, Rate With Points and Net Savings Over Full Term. A buyer testing points is usually discussing a specific deal, and often a seller credit.

Follow-up that works

  • Ask how long they expect to keep the loan. Compare that with the break-even month.
  • If a seller credit is on the table, compare points with closing-cost coverage, and confirm credit limits with their lender.
  • Encourage them to ask their lender for pricing at several point levels.

Say it like this · Explaining a seller credit to a buyer
The seller's $8,000 credit could buy about two points. That drops your payment around $130 a month, and you'd break even in about five years if you were paying for the points yourself. Since the seller is paying, you keep the saving from day one.
Before and after

Your page before and after this calculator

BeforeAfter

Before: Price reduced $10,000

  • Saves the buyer about $65 a month
  • Signals a weak listing
  • The seller gives up equity for a small payment change

After: Seller-paid rate buydown

  • Can lower the payment more for the same cost
  • The listing price holds
  • Buyers see the payment effect immediately
Reading the results

What each result means for your follow-up

The same figures your visitor sees arrive in your lead record. Here's how to read the ones that matter.

Break-Even
How many months of savings it takes to recover the cost of the points. Compare it with how long the buyer expects to keep the loan.
Monthly Saving
The payment reduction from the lower rate. It's often the most persuasive number for buyers comparing a buydown with a price cut.
Net Savings Over Full Term
Total saving over the whole loan, minus the cost of points. Few loans run their full term, so treat this as an upper bound.
What can go wrong

Mistakes that cost agents the lead

Assuming a fixed rate cut per point

How much one point lowers the rate varies by lender and market. Use the lender's pricing for the 'rate cut per point' input, not a rule of thumb.

Ignoring concession limits

Loan programs limit how much a seller can contribute. Confirm the allowed amount with the buyer's lender before writing a buydown into an offer.

Confusing permanent and temporary buydowns

Discount points permanently lower the rate. A temporary buydown (such as a 2-1) lowers it for a year or two. This calculator models permanent points.

Definitions shown in the calculator (9)
Discount points
Upfront fees paid to the lender at closing in exchange for a lower interest rate. One point costs 1% of the loan amount, so two points on a $300,000 loan cost $6,000. How much each point lowers the rate is set by the lender and varies, which is why this calculator asks for the rate cut per point.
Break-even point
The number of months it takes for the lower monthly payment to repay the upfront cost of the points, found by dividing the cost of points by the monthly saving. If you sell or refinance before reaching it, the points cost more than they saved. After it, every remaining month is net savings.
Rate cut per point
How much the interest rate falls for each point purchased. A quarter of a percentage point per point is a common rule of thumb, but lenders price points differently and the reduction may shrink as you buy more. Use the figure from your lender’s rate sheet, because the break-even result depends heavily on it.
Cost of points
The cash paid at closing for the points: number of points times 1% of the loan amount. It is money spent up front that you recover only gradually through lower payments. Points can sometimes be paid by the seller or deducted on your taxes, neither of which this calculator models.
Monthly saving
The difference between the principal-and-interest payment without points and the payment at the reduced rate. It is the return you get each month on the money spent on points. Taxes and insurance are unaffected by points, so they are left out of this comparison.
Net savings over full term
Total payment savings over the full loan term minus the cost of the points. It assumes you keep the loan to the last payment, which few borrowers do. Treat it as the best case; the break-even point is the more practical guide if you might move or refinance.
APR
Annual percentage rate: a yearly cost of borrowing that folds points and certain lender fees into the interest rate. Buying points lowers the note rate but, because the points count as a finance charge, the APR falls by less. Comparing APRs helps when lenders offer different mixes of rate and points.
Interest rate
The annual note rate charged on the unpaid balance. Here it is your base rate before buying points; the calculator subtracts the rate cut for each point to find the rate with points. Both payments are then calculated with standard amortization over the same term, so only the rate differs.
Loan term
The number of years over which the loan is scheduled to be repaid. In a points decision, the scheduled term matters less than how long you actually keep the loan. A longer term spreads a given rate cut into smaller monthly savings, which pushes the break-even point further out.
Calculator disclaimer

Estimates only. Whether points pay off depends on the exact rate reduction offered and how long you keep the loan. Confirm point pricing with your lender.

Questions by topic

Mortgage Points Calculator: questions agents ask

What is one mortgage point?

One discount point costs 1% of the loan amount. On a $350,000 loan, one point is $3,500. How much it lowers the rate depends on the lender's pricing.

How is break-even calculated?

Cost of points divided by the monthly saving, giving the number of months to recover the cost. The calculator also shows net savings over the full term after subtracting the cost.

Does it model temporary buydowns like a 2-1?

No. It models permanent discount points. A temporary buydown lowers the payment for the first year or two only, so its value is the sum of those early savings.
