A lower monthly payment and a lower total cost are often different offers. The comparison shows both so the trade-off is visible.
APR here folds the fees you entered into the borrowing cost. Lenders may include a different set of fees in their disclosed APR.

Mortgage offers rarely differ in one dimension. One has a lower rate and higher fees. One has a shorter term and a higher payment. One includes points that only pay off if you stay long enough. Compared on any single number, the answer is confident and frequently wrong.
These tools separate the dimensions. Total cost and monthly payment are reported side by side, APR shows what the fees are worth as a rate, and the points calculator asks the only question that matters about a buydown: how long are you staying?

Why use MortgageComparisonTools
Cost and cash flow separated
A longer term costs more and leaves more cash each month. Neither is universally right, and seeing both is how you choose.
Fees expressed as a rate
APR folds up-front costs into the rate, which makes a low-rate-high-fee offer comparable to the opposite.
Points judged against tenure
A buydown is a bet on how long you keep the loan. The break-even in months is the number that decides it.
Biweekly plans explained honestly
Twenty-six half payments equal thirteen monthly payments. The thirteenth is the entire effect, and you can arrange it yourself for nothing.
How it works
- Compare the two offers on total cost and on payment - they rarely agree.
- Convert each offer’s fees into an APR to see what they are worth as a rate.
- If points are involved, check the break-even against how long you expect to stay.
- Ignore biweekly marketing and compare it against paying the same extra yourself.
Frequently asked questions
Should I compare rate or APR?
APR when the terms match and the fee sets are comparable. When terms differ, compare total cost and payment separately - APR cannot express both at once.
Is a 15-year mortgage always better?
It always costs less in total interest. Whether it is better depends on whether the higher payment is comfortable and on what else the difference could be doing.
Are discount points worth buying?
Only if you keep the loan past the break-even point. Since most mortgages do not run to term, be conservative about how long you expect to stay.
Is a biweekly payment plan a good deal?
The underlying effect - one extra payment a year - is genuinely useful. Paying a third party to arrange it usually is not, since your servicer will normally do it free.
