Your real monthly payment — with taxes & PMI

See your real monthly cost — not just principal and interest. This calculator bakes in realistic property tax, homeowners insurance, and PMI (if your down payment is under 20%), so the PITI number you see is the one you’ll actually owe.

Your real rate depends on credit, loan type, and market conditions. Estimates only based on national averages. Always confirm with a licensed lender.

This payment may be overstretched

At $3,043/mo, a $85,000-income household would spend 43.0% of gross pay on housing — above the 36% stretched ceiling. Consider a lower price, bigger down payment, or waiting for rates to drop before locking in this budget.

Because your down payment is 10.0%, PMI of $225/mo is baked into that payment. See how PMI affects your payment.

Benchmark: a typical $85,000/yr household can comfortably afford about $1,983/mo for housing (28% front-end) and up to $2,550/mo at the 36% stretch ceiling.

What changed your payment most?

All values are the change in total monthly payment from your current scenario.

Scenario
+$50k home price
+1% rate
+10% down payment
Change in monthly payment+$380+$244−$484
New total monthly$3,424$3,287$2,559

Biggest mover: a 10% larger down payment. If you have flexibility on one of those levers, that’s where focus pays off.

That’s why shopping at least 3 lenders typically saves thousands over the life of a loan.

Common mistakes buyers make

Budgeting only for principal & interest
Most quick quotes show just P&I. Real payments include property tax, homeowners insurance, PMI (under 20% down), and HOA where it applies. Those extras often add $708/mo on top.
Assuming today’s rate is tomorrow’s rate
Rates move daily. A rate-locked pre-approval only protects you for 30–60 days. If you’re 3+ months from buying, model a range of rates so a move upward doesn’t blow up your budget.
Maxing out what a lender approves
Lenders can approve up to 43–50% back-end DTI. That doesn’t leave room for retirement, kids, or unexpected repairs. Keep total housing under 28–30% of gross if you can.
Ignoring closing costs and reserves
Beyond the down payment, expect 2–5% of the price in closing costs plus a few months of reserves. Estimate your cash to close.

Now that you know the monthly, get a realistic estimate of what you’ll owe at the closing table — lender fees, title, escrow, and prepaid items.

How it’s calculated

The PITI formula, in plain English

Your monthly payment is made up of four parts: Principal, Interest, property Taxes, and homeowners Insurance. If you put less than 20% down, private mortgage insurance (PMI) is added on top.

  • • Principal & interest use the standard amortization formula.
  • • Property tax defaults to 1.1% of home value / year (US average).
  • • Homeowners insurance defaults to 0.35% of home value / year.
  • • PMI defaults to 0.75% of loan amount / year when your LTV > 80%.
Tips

How to lower your monthly payment

  • Increase your down payment to 20%. You’ll eliminate PMI and reduce the loan balance interest is charged on.
  • Improve your credit score. A 760+ score typically gets the best rates and PMI pricing.
  • Shop at least 3 lenders. Borrowers who get multiple quotes can save thousands over the life of the loan.
  • Consider a 15-year term if the higher payment fits your budget — you’ll save huge on interest.
How to use this calculator

From home price to monthly payment in 30 seconds

  1. 1. Enter the home price. Use the actual price or your budget target.
  2. 2. Set your down payment. Move the slider until your cash-to-close feels realistic.
  3. 3. Pick a loan term and rate. The calculator defaults to current 30-year averages.
  4. 4. Adjust tax and insurance if you know local averages — otherwise the national defaults are close.
  5. 5. Check the full PITI payment. That’s what you’ll owe every month.
  6. 6. Play with scenarios. How does 20% down change it? What about 15 years? Plan before you commit.
