Where the money actually goes
On a 20-year mortgage of $750,000 at 7.5%, the monthly P&I payment is $6,041.95. That's the simple part. The interesting part is how that payment splits between interest and principal across the life of the loan.
Year 1 — when the bank wins
In the first year, you'll pay $72,503 in P&I across twelve months. Of that, $55,679 goes to interest and only $16,824 chips away at the actual loan balance. That's roughly 77% interest, 23% principal — the bank's profit-front-loading, and the reason early extra-principal payments are so valuable.
Year 20 — when you finally win
By the final year of a 20-year loan, the split flips. You'll pay $72,503 in P&I that year, but only $2,862 of it is interest — the rest, $69,642, is principal. By then you own enough of the house that the lender's monthly take has shrunk to barely anything.
How this compares to nearby scenarios
Small changes to the inputs move the payment in non-obvious ways. Here's how this scenario stacks up against its neighbors:

- $750,000 at 6.5% for 20 years — monthly payment is $-450/mo with the rate 1.0% lower.
Frequently asked questions
Does this payment include taxes and insurance?
No. The $6,041.95 above is principal and interest only (P&I) — what the lender directly receives. Property taxes, homeowners insurance, and (if your down payment is under 20%) PMI all sit on top. As a rough rule of thumb, the full PITI payment for a primary residence runs 25–35% higher than P&I alone. Use the full mortgage calculator to add those numbers in.
What if I make extra principal payments?
Extra principal payments save interest disproportionately because they're applied against the part of the loan that hasn't been paid yet — and on a fresh mortgage, that's almost the whole balance. On this $750,000 loan at 7.5%, paying an extra $200 a month from day one would shave roughly 16 months off the 20-year term and save somewhere in the neighborhood of $57,351 in lifetime interest. The exact figure depends on when in the month payments post, but the magnitude is right.
How much income do I need to qualify for this loan?
The standard front-end ratio is 28% — your full PITI shouldn't exceed 28% of gross monthly income. Working backwards from $6,041.95 in P&I (plus another 25–35% for taxes, insurance, and PMI), you're looking at roughly $323,676–$349,570 in gross annual household income to qualify comfortably. Some lenders go higher, but lenders that push 36–40% front-end ratios are setting you up to be house-poor.
Is this rate good?
A 7.5% rate on a 20-year fixed mortgage is comparable to typical conforming-loan rates in the mid-2020s — neither historically cheap (which was the 2.5–3.5% range of 2020–2021) nor historically expensive (which was 12–18% in the early 1980s). The bigger question is whether your rate is competitive — get three Loan Estimates from different lenders and compare APRs, not just rates. Even a 0.25% spread on this loan size costs roughly $27,640 over the life of the loan.
