How to use this calculator
- Confirm loan amount: Purchase price minus down payment (plus financed closing costs if any).
- Enter note rate as APR for simplicity: If you have separate APR vs note, use the APR that matches your disclosure for apples-to-apples.
- Layer escrow components: Tax, insurance, PMI, HOA—add each if you want “true monthly” not P&I only.
What moves the payment
Monthly payment on a fixed-rate amortizing loan is driven by principal, APR, and term. Extra principal reduces balance faster; biweekly schedules effectively add one extra payment per year in many setups. Refinance math adds closing costs and resets amortization—break-even is months of savings versus upfront cost.

Real-world example
- Example: $340,000 loan, 6.625% fixed, 30 years: P&I lands near $2,175/mo (illustrative). Add ~$400 taxes + $110 insurance → ~$2,685/mo before HOA.

What this means
Early amortization is interest-front-loaded: two loans with the same payment differ mainly by rate and term on total interest paid. Extra principal in the first third of the loan trims lifetime interest more than the same dollars after half the term.
FAQ
Why is my payment higher than the Zillow default?
Zillow often shows P&I. Taxes, insurance, PMI, and HOA are additive lines in a full housing payment.
Does a 15-year loan always save money?
Total interest often drops, but payment rises. Choose based on cash flow and goals.
Is this a loan commitment?
No. Outputs are educational estimates. Final payments, APR, and fees come from your lender’s disclosures.
Why does my amortization schedule differ slightly?
Rounding, day-count conventions, and first-payment timing shift pennies. Use the schedule for directionally correct totals.
