Build the payment before you compare it
Follow the assumptions into the result so a single headline number never stands alone.

How the calculation works
Every row starts from the previous month’s closing balance. Interest for the month is the opening balance times the monthly rate; the remaining scheduled payment reduces principal, then any extra principal reduces the balance further.
Because interest is charged on the opening balance, a falling balance produces a falling interest charge and a rising principal share within the same fixed payment.
Worked example
Worked example: month 60 of the default loan. $340,000 loan at 6.25% for 30 years, no extra payments, viewed at payment 60 of 360.
- By month 60 the opening balance has fallen to about $317,785.
- That month’s interest charge is about $1,655.13, and about $438.31 of the $2,093.44 payment goes to principal.
- The closing balance after payment 60 is about $317,346.62.
Roughly 79% of payment 60 is still interest, compared with about 85% in month 1, illustrating how the split shifts over time.
Assumptions
- Property tax, insurance, HOA and PMI shown in the export are level monthly estimates, not a servicer’s actual escrow analysis.
- Rows and on-screen totals are rounded for readability; the CSV export rounds each value to the cent.
When to use this
Use this page to see exactly how much of any given payment reduces principal versus covering interest, or to export a full schedule for your records.
Common mistakes
- Expecting the on-screen rounded totals to match the CSV to the exact cent in every row.
- Forgetting that housing costs like tax and insurance can continue after the mortgage itself is paid off.
Big decisions. Clearer answers.
What is actually in a mortgage payment?
Separate principal and interest from taxes, insurance, HOA, PMI and upfront closing cash.
15-year or 30-year mortgage: compare the right numbers.
Compare required payments, interest costs and the flexibility of extra payments on 15-year and 30-year fixed mortgages.
PMI removal: a request is not the automatic date.
Understand the difference between requesting conventional PMI cancellation at 80% and automatic termination on the original schedule.
What your amortization schedule is telling you.
Each month begins with the previous closing balance. Interest is charged on that opening balance, then the remaining scheduled payment reduces principal. Extra principal reduces the balance further. As the balance falls, the next month has less interest and more principal within the same scheduled payment. The annual view groups payments by calendar year, so the first and last years can be partial years. Export the full monthly detail for a cent-level breakdown.
A few things you
might be wondering.
No fine-print scavenger hunt required.
Read the full methodology
Why does so much of my early payment go to interest?
The outstanding balance is largest at the beginning. With a fixed note rate, a larger opening balance generates a larger monthly interest charge.
Why can the last payment be smaller?
The model caps principal at the remaining balance, so you never pay more principal than you owe. Extra payments can bring that final payment forward.
Why might displayed totals differ by a dollar?
Rows and summary values are rounded for readability, while the underlying calculations retain full precision. The CSV rounds each exported dollar value to cents. Real servicers may use different rounding conventions.
Does the schedule include escrow?
The CSV includes monthly estimates for property tax and insurance, plus HOA and PMI. The on-screen table emphasizes the loan balance. These housing costs can continue after the mortgage is paid off.
