What this mortgage points calculator does
This calculator shows the effect of mortgage points. You enter the loan, the rate and the term. You add the cost of buying points. The tool then shows your lower payment. It also finds your break-even point. You can see if points pay off. The result helps you decide whether to buy them.
What mortgage points are
Mortgage points are an upfront fee. You pay them to lower your interest rate. One point usually costs one percent of the loan. In return, your rate drops a little. This is also called buying down the rate. The lower rate then saves you money. The trade is cash now for savings later.
How points lower your rate
Each point you buy cuts your rate. A lower rate means a smaller payment. It also means less total interest. The exact drop varies by lender. More points usually mean a bigger cut. The savings build up over the years. The longer you stay, the more you gain.
The cost of a point
One point is one percent of the loan. On a large loan that is real money. You pay it at closing, upfront. This adds to your closing costs. It is money you cannot use elsewhere. So the choice has a clear cost. Weigh it against the monthly saving.
The break-even point
The break-even point is the key number. It is when your savings repay the cost. Before it, you have not gained yet. After it, the savings are pure benefit. A shorter break-even is better. The calculator finds this date for you. Compare it to how long you will stay.
When points are worth it
Points are worth it if you stay long. A long stay passes the break-even point. Then the lower rate saves real money. They suit a loan you will keep. They reward patience over many years. The math favours a long horizon. Run your own numbers to be sure.
When to skip points
Skip points if you may move soon. A short stay never reaches break-even. Then the upfront cost is wasted. Skip them if cash is tight now. The money may help more elsewhere. A bigger down payment can be better. Think about your plans before you buy.
How to use it
Enter the loan amount and rate. Add the term and the cost of points. Read the lower payment and total saving. See the break-even point the tool shows. Then compare staying short versus long. Decide if the upfront cost makes sense. Use it to guide a smart choice.
Points versus a bigger down payment
Both use cash you have upfront. Points lower your interest rate. A bigger down payment lowers your balance. Each can reduce your monthly cost. A larger deposit also builds equity faster. Points only pay off if you stay. Compare both before you spend the cash.
Common mistakes to avoid
A common mistake is ignoring break-even. Points fail if you move too soon. Another is buying points with no spare cash. Some forget the deposit alternative. Others assume points always save money. They only help over a long term. A careful check avoids these traps.
A final tip
Buy points only with a long horizon. Confirm your break-even point first. Make sure you have cash to spare. Compare points to a bigger deposit. Keep an emergency fund either way. Review your plans before you commit. The right call depends on how long you stay.
