Is it worth paying points to lower the mortgage rate, or is it better to keep the money? This mortgage points calculator (discount points / rate buydown) tells you. From the loan amount, the rate without points, the rate with points, the cost of the points and the term, it calculates the payment without and with points, the monthly saving, the break-even point in months and the total saving over the whole term. It is the right tool to decide whether the upfront investment to reduce the rate really pays off, based on how long you plan to keep the mortgage.

What mortgage points are

Mortgage points (discount points) are a sum you pay the bank upfront, in exchange for a lower interest rate for the whole term of the mortgage. In practice you "buy" a reduced rate: one point typically costs 1% of the loan amount and reduces the rate by a fraction (often around 0.25%). It is a trade-off between a larger upfront outlay and a lower monthly payment: the worth depends on how long you keep the mortgage.

How discount points work

Paying points means prepaying part of the interest to obtain a lighter payment. The more points you buy, the lower the rate and the smaller the payment, but the higher the upfront cost. The mechanism makes sense only if the monthly saving, accumulated over time, exceeds the cost paid at the start. That is why the key question is not "how much do I save per month", but "in how much time do I recover the cost of the points": it is the break-even point.

The break-even point

The break-even point is the number of months needed for the monthly saving on payments to equal the initial cost of the points. It is calculated by dividing the cost of the points by the monthly saving. If the points cost €4,000 and save €65 a month, the break-even is about 61 months (just over 5 years). From then on, the points start to gain you money: if you keep the mortgage beyond the break-even, they are worth it; if you pay it off or refinance earlier, you lose out.

How the calculator works

Enter five values: the loan amount, the rate without points, the rate with points, the cost of the points and the term. The calculator computes the payment in the two scenarios with the amortization formula, derives the monthly saving, divides the cost of the points by the saving for the break-even, and projects the total saving over the whole term. Change the values to see how the break-even and the worth vary.

The values you need

The loan amount is the financed capital. The rate without points is the standard one offered. The rate with points is the reduced one you get by paying the points. The cost of the points is the sum you pay upfront to obtain the lower rate. The term is the number of years of the mortgage. Compare the bank's offers: the two rates and the cost are the key numbers for the decision.

The payment without and with points

The calculator shows the monthly payment in the two scenarios: with the full rate and with the rate reduced by the points. The difference between the two is the saving you get each month by paying the points. On a €200,000 mortgage over 30 years, going from 6.5% to 6.0% lowers the payment from about €1,264 to about €1,199. Seeing both payments lets you understand concretely by how much the monthly payment lightens.

The monthly saving

The monthly saving is the difference between the payment without points and the one with points: how much less you pay each month thanks to the reduced rate. It is the engine of the break-even calculation. A larger saving shortens the time to recover the cost of the points. Be careful: a monthly saving that seems small (tens of euros) can still translate into thousands of euros over a long mortgage, but only if you keep it long enough to pass the break-even.

The break-even point in detail

The break-even is the heart of the decision. If you plan to sell the home or refinance before the break-even point, the points are not worth it: you do not recover the upfront cost. If instead you plan to keep the mortgage beyond the break-even, every extra month is a net gain. That is why the points suit those who are sure to stay long in the same home with the same mortgage, and are not advised for those who plan to move or refinance within a few years.

The total saving over the term

The total saving is how much you gain overall if you keep the mortgage for the whole term: the monthly saving multiplied by all the months, minus the cost of the points. On a thirty-year mortgage, it can amount to several thousand euros. It is the "maximum prize" of the points, obtainable only by staying to the end. It is useful to understand the potential gain, but it must always be compared with the concrete risk of paying off or refinancing earlier than expected.

How much a point costs

The cost and the effect of the points follow indicative rules:

These are indicative values: the actual cost and reduction vary by lender and market. Enter the real numbers of your offer in the calculator.

When points are worth it

The worth depends almost entirely on how long you stay in the mortgage relative to the break-even:

If you do not know how long you will keep the mortgage, a short break-even (within a few years) makes the points less risky.

The break-even by monthly saving

At equal cost of the points, the break-even depends on the monthly saving:

A higher monthly saving (a more marked rate reduction) shortens the break-even and makes the points more worthwhile.

Points vs a larger down payment

Having money available, an alternative to points is to make a larger down payment, reducing the loan amount. The larger down payment lowers the payment by reducing the capital, while the points lower it by reducing the rate. In general, the points are worth it if you stay long in the mortgage; the larger down payment is more flexible and reduces the debt immediately. It is worth comparing both options with the numbers before deciding.

Negative points (lender credit)

There is also the opposite operation: negative points (or lender credit), in which you accept a higher rate in exchange for a contribution by the bank to the closing costs. It is useful to those with little upfront cash or who plan to keep the mortgage a short time, because it reduces the upfront costs in exchange for a higher payment. It is the inverse logic of discount points: the calculator can help you compare this scenario too by inverting the roles of the two rates.

Common mistakes

• Looking only at the monthly saving, ignoring the break-even point.
• Buying points if you plan to refinance or sell within a few years.
• Forgetting that the cost of the points is money that could earn elsewhere.
• Not comparing the points with the alternative of a larger down payment.
• Assuming standard rate reductions without checking the real offer.

How to use the calculator

Enter the amount, the two rates (with and without points) and the cost of the points, then the term. You will immediately get the two payments, the monthly saving and the break-even point. Compare it with how long you plan to keep the mortgage: if the break-even comes well before, the points are worth it. Try different costs and rate reductions to understand which is the most advantageous offer among those the bank proposes.

Practical example

You have a €200,000 mortgage over 30 years: without points the rate is 6.5%, by paying €4,000 of points it drops to 6.0%. The result: a payment without points of about €1,264, a payment with points of about €1,199, a monthly saving of about €65, a break-even point at about 61 months (just over 5 years) and a total saving of about €19,400 if you keep the mortgage whole, with the verdict "worth it only if you keep the mortgage long". If you plan to stay beyond 5 years, the points make sense. Enter your numbers for your real situation. This tool is an informational estimate; points, rate reductions and practices vary by country and lender.

Frequently asked questions

What are mortgage points?

They are a sum you pay the bank upfront to obtain a lower interest rate for the whole term. One point typically costs 1% of the amount and reduces the rate by a fraction, often around 0.25%.

Is it worth paying points?

It depends on how long you keep the mortgage. The points are worth it if you stay beyond the break-even point, the time needed for the monthly saving to recover the upfront cost. If you sell or refinance earlier, you lose out.

What is the break-even point?

It is the number of months in which the monthly saving equals the cost of the points: cost divided by monthly saving. With €4,000 of points and €65 of saving a month, the break-even is about 61 months (just over 5 years).

How much does a point reduce the rate?

Generally about 0.25% per point, but it varies by lender and market. The actual reduction is the one the bank indicates in the offer: enter the two real rates (with and without points) in the calculator.

How much does a point cost?

A point typically costs 1% of the loan amount. On €200,000, a point is €2,000. You can often buy fractions of a point (half a point, etc.) for a proportional rate reduction.

When is it NOT worth buying points?

When you plan to sell the home or refinance before the break-even point. In that case you do not recover the upfront cost. The points are not advised for those who plan to move within a few years.

Points or a larger down payment?

The points lower the payment by reducing the rate; a larger down payment lowers it by reducing the capital. The points are worth it if you stay long; the down payment is more flexible and reduces the debt immediately. It is worth comparing them with the numbers.

What are negative points?

They are the opposite: you accept a higher rate in exchange for a contribution by the bank to the closing costs (lender credit). Useful to those with little upfront cash or who keep the mortgage a short time, in exchange for a higher payment.

Are points tax-deductible?

In some countries the points, being prepaid interest, may have a favourable tax treatment; in others not. The rules vary a lot: check your country's regulation or ask an advisor. The calculator works on gross values.

Does the calculation work for fixed and variable rates?

The calculation is designed for a fixed-rate comparison, where the two rates stay constant for the whole term. With a variable rate the future saving is uncertain, so the break-even should be considered only as an indicative estimate.

How do I use the calculator to decide?

Enter the two rates and the cost of the points from the offer, read the break-even point and compare it with how long you plan to keep the mortgage: if you expect to stay well beyond the break-even, the points are worth it.

Does it work for any country and currency?

The calculation is universal and uses the values in your currency. The practice of points is more common in some markets than others; in any case, wherever there is the possibility to lower the rate by paying more upfront, the break-even logic applies.
