What your result means

Your estimated principal and interest payment is $2,076 per month, or about $2,601 once taxes, insurance, PMI, and HOA are included. Over the 30-year term you may pay roughly $427,188 in interest — about 133% of the $320,000 borrowed. Because mortgages amortize, early payments are mostly interest and the principal portion grows over time.

Compare scenarios before relying on the starting estimate

This estimate uses the standard amortization formula with your taxes, insurance, PMI, and HOA assumptions. Use the comparison below to see how a different rate, down payment, term, or extra payment would change the monthly cost and total interest.

Costs beyond the mortgage payment

The monthly payment is only part of owning a home. These costs are commonly reviewed when estimating total ownership cost. Official lender estimates, insurance quotes, local taxes, and HOA documents may differ from these assumptions.

Property tax & insurance

These recur for as long as you own the home and tend to rise over time, even after the loan is paid off.

Maintenance & repairs

Some planning frameworks include a maintenance reserve (often cited around 1% of home value per year), but actual repairs vary by property age, location, and condition.

Closing costs & transfer taxes

Closing costs, and in many regions stamp duty or transfer tax, are commonly reviewed on top of the down payment at purchase.

Emergency fund

Many planning frameworks include a cash reserve for unexpected costs.

Other debts & income stability

Income stability and recurring obligations can affect how a household reviews a long-term payment estimate.

Rate changes on adjustable loans

If the loan is adjustable or floating, the payment can rise when rates reset. Compare higher-rate scenarios before relying on the starting estimate.

Planning checks to review

Use these neutral checks when reviewing the estimate. Official lender documents may differ.

  • Consider whether the estimated payment leaves room for other recurring costs.
  • Review whether property taxes and home insurance are included — not just principal and interest.
  • At 20%+ down, many loans skip PMI. Confirm the rule with your lender.
  • Review closing costs and cash reserves alongside the down payment.
  • Compare the estimated lifetime interest (about $427,188) with your budget, alternatives, and official lender estimates.

Lower rate reduces total interest with little change to cash upfront.

Larger down payment lowers the loan amount and may reduce or remove PMI, but needs more cash at closing.

Shorter term usually raises the monthly payment while cutting lifetime interest.

Extra, biweekly-equivalent, and one-time payments applied to principal can shorten the payoff and reduce interest.

Escalated costs hold the loan fixed but let taxes, insurance, and HOA rise — so lifetime out-of-pocket grows even though the payoff is unchanged.

Lifetime cost is cash at closing plus every payment over the life of the loan, under these assumptions.

“Best for” badges identify which scenario leads on a single metric (monthly payment, total interest, payoff speed, upfront cash, or lifetime cost) — not an overall recommendation. “vs base” shows the change against your base case. The extra-payment row uses $200 per month; the larger-down-payment row adds $20,000 upfront. Escalated-costs row is a stress test, not an optimization, and does not receive badges.

In the early years, most of each payment goes toward interest because the balance is large. Over time the split flips and more goes toward principal — which is why earlier principal reductions can have a larger effect under long-term amortization assumptions.

The $2,076 loan payment and the $2,601 that leaves your account

Your result splits into two layers: the loan payment itself (principal and interest, driven by your rate, term, and loan amount) and the recurring costs of owning the home (property tax, homeowners insurance, PMI, and HOA, where they apply). Add them together and you get the full monthly housing estimate — the number that needs to fit your budget, not just the loan payment a lender quotes first. The lifetime figures below the monthly numbers show total interest paid over the full term and the projected payoff date, both of which shift immediately when you change the rate, term, down payment, or add extra payments. Use the amortizationPaying off a loan through regular payments that gradually shift from mostly interest to mostly principal. schedule to see the principal-to-interest split move month by month, and the scenario comparison to test decisions side by side before you commit to one.

A $400,000 home with 20% down ($80,000), a $320,000 loan, a 6.75% fixed rate, and a 30-year term produces principal and interest of about $2,076 a month. Add estimated property tax of $400/month (1.2% annually) and homeowners insurance of $125/month, and the full monthly housing payment comes to roughly $2,601 before any HOA dues. Over the full 30-year term, this loan accrues about $427,188 in total interest — more than the original loan amount. Because the down payment is 20%, PMI does not apply here; a smaller down payment would add a mortgage-insurance line until the loan-to-value ratio falls below 80%. Change any input — rate, term, or down payment — and every one of these figures updates immediately.

That $525 gap is the point: this estimates the whole monthly cost of a home loan — principal and interest, plus taxes, insurance, PMI, and HOA where they apply — from the price, down payment, rate, and term you enter. It projects total interest and the payoff date too, so you can compare scenarios before talking with a lender.

Principal and interest is one line of five

The core formula computes the level monthly principal-and-interest payment that fully repays the loan over its term. Add recurring ownership costs — property tax, insurance, PMI, and HOA — to get the full monthly housing payment: the number that actually leaves your account each month.

Monthly principal & interest

M = P × [ r(1+r)ⁿ ] / [ (1+r)ⁿ − 1 ]

The level payment that repays the loan over its term. At 0% interest it simplifies to M = P / n.

Total monthly housing payment

P&I + tax + insurance + PMI + HOA

The full cost of owning, not just the loan payment — the number that actually needs to fit your budget.

Variable glossary

  • P — loan amount (home price − down payment)
  • r — monthly interest rate (annual ÷ 12 ÷ 100)
  • n — number of payments (term in years × 12)
  • M — monthly principal & interest payment

Written out, that first line is the standard amortizing-loan formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1], where P is the loan amount, r is the monthly interest rate, and n is the number of monthly payments. It produces a level payment that fully repays the loan by the end of its term. The other four lines never amortize: taxes, insurance, PMI, and HOA are recurring charges on their own schedules, entered separately rather than folded into P.

Six assumptions sit behind every figure above:

  • Loan amount is calculated from home price minus down payment.
  • Principal and interest use the standard fixed-rate amortizing loan formula.
  • Annual property tax and homeowners insurance assumptions are converted to monthly costs.
  • PMI is estimated when down payment assumptions imply a loan-to-value ratio above 80%.
  • Extra payments are modeled as additional principal payments that can shorten payoff time and reduce interest.
  • Closing costs, points, income, and existing debt are optional planning inputs and do not represent underwriting or approval.

PMI starts below 20% down and ends at 78% loan-to-value

Private mortgage insurance is usually required when your down payment is under 20% (loan-to-value above 80%). It protects the lender, not you. You can typically request cancellation once the balance reaches 80% of the original value, and it often falls off automatically at 78%. Extra principal payments or rising home value get you there sooner. The calculator applies it automatically below 20% down — which is why the first-time-buyer preset above charges PMI on a $400,000 home with $20,000 down, and the 20%-down presets show no PMI line.

The 28% and 36% caps that turn a payment into a price ceiling

The affordability section runs the arithmetic in both directions. Enter your gross income and existing monthly debts and it applies the housing-ratio and debt-to-income caps you set — 28% and 36% by default, both editable — to estimate a maximum comfortable payment. Reverse-solve instead and it works back from a target payment to a maximum home price. Neither direction is an approval — those caps are conventions you can move, not underwriting.

Switch to India and the payment is called an EMI

The region selector is not a currency relabel. Switch to United Kingdom, Canada, Australia, or India and the calculator relabels and adjusts for local costs — Stamp Duty Land Tax in the UK, CMHC mortgage default insurance in Canada, Lenders Mortgage Insurance in Australia, or stamp duty and registration charges in India — with currency and every figure staying fully editable. In India mode the monthly payment is what is commonly called the EMI, the equated monthly installment, and “home loan” is the local term for what this page calls a mortgage. The principal-and-interest math is identical either way.

Five mortgages this calculator gets wrong

This calculator is built for a standard fixed-rate purchase mortgage. It is probably not the right tool — and something else will serve you better — in these cases:

You have an adjustable-rate (ARM), interest-only, VA, or USDA loan.

This models a standard fixed-rate loan only — it does not adjust the rate after an intro period, model interest-only payments, or add a VA funding fee or USDA guarantee fee into the loan.

Ask your lender for a rate-adjustment or fee illustration specific to your loan type — we do not yet have a specialized calculator for these.

You already have a real Loan Estimate from a lender.

A Loan Estimate is a binding federal disclosure with your actual rate, fees, and closing costs. No calculator, including this one, should outrank a document that is already binding.

Use the lender’s numbers. Come back here only to compare scenarios before you reach that stage.

You are refinancing an existing mortgage, not buying.

Refinancing compares your current balance and rate against a new one, plus closing costs and a break-even point — different questions than a purchase loan asks.

Try the Mortgage Refinance Calculator instead.

You want a pure amortization schedule for a loan that is not a mortgage.

This tool bundles in property tax, insurance, PMI, and HOA assumptions that do not apply to an auto, personal, or business loan.

Try the Amortization Schedule Calculator, which works for any fixed loan.

You are deciding whether to rent or buy at all.

This estimates the mortgage payment, not the full trade-off — the opportunity cost of your down payment, expected appreciation, and moving costs are not modeled here.

Try the Rent vs Buy Calculator instead.

None of these are hard walls — you can still use this calculator to sanity-check a number or compare a scenario. They are the cases where we would rather point you somewhere more accurate than let an estimate stand in for the real thing.

Where this estimate and your lender’s Loan Estimate will disagree

A lender quote reflects your exact rate, fees, points, escrow setup, mortgage insurance, and rounding, plus your credit profile and the property — none of which a calculator can know precisely. Treat this estimate as a planning figure and rely on the lender’s official Loan Estimate for the binding numbers.

Three limitations are structural:

  • Does not include every lender fee, rate-lock term, escrow rule, closing cost, tax reassessment, or insurance quote.
  • PMI and tax estimates are simplified and may differ from lender, insurer, county, or escrow calculations.
  • This is not a loan approval, preapproval, quote, or financial recommendation.

And none of it is financial advice. Every result here is an educational estimate built from your assumptions and a standard formula — not a loan offer, underwriting decision, or financial recommendation. For a binding rate, payment, or approval, use your lender’s official Loan Estimate and speak with a qualified professional.

What's changed (4 updates)

Published 7 June 2026

  1. Published the mortgage payment calculator with formula and amortization.
  2. Added a lender/offer comparison and a deeper affordability check.
  3. Added a decision receipt and reviewed assumptions for accuracy.
  4. Sharpened the page title and opening copy around the monthly-payment questions readers actually ask, linked the CFPB and Freddie Mac sources directly instead of burying them, and memoized the 9-scenario comparison panel so it no longer recomputes on unrelated interactions.
