A mortgage calculator tells you the true monthly cost of a home loan — not just principal and interest, but the full PITI picture: property tax, home insurance, PMI, and HOA fees layered on top. NeftCal's mortgage calculator goes further as a mortgage extra payment calculator and mortgage payoff calculator, letting you model extra monthly, yearly, and one-time payments to see exactly how much sooner you'd be mortgage-free and how much interest you'd save. It's built for anyone buying, refinancing, or already repaying a home loan who wants real numbers instead of a lender's rounded estimate.
Most online quotes only show principal and interest, which understates what actually leaves your bank account every month. Property tax, home insurance, and — if your down payment is under 20% — private mortgage insurance (PMI) can easily add several hundred dollars a month on top of the base payment. This calculator combines all of them into one PITI calculator so your budget reflects reality, and it supports 9 currencies with region-typical starting interest rates.
Home buyers sizing up affordability before house-hunting, current homeowners deciding whether extra principal payments are worth it, people comparing 15-year vs. 30-year terms, and anyone modeling a refinance scenario all benefit from seeing the full monthly number and its long-term trajectory rather than a single static payment figure.
A mortgage is usually the largest recurring expense in a household budget, and small differences in rate, term, or down payment compound into tens of thousands of dollars over 15-30 years. Understanding your full PITI payment — and how PMI, property tax growth, and extra payments interact with it — is central to deciding how much home you can actually afford and how aggressively to pay it down.
Principal & interest come from the standard amortization formula; taxes, insurance, PMI, HOA and extra payments are layered on top
From home price to full payment breakdown in under a minute
Input the total purchase price of the home and select your currency from the 9 supported options — the calculator pre-fills a region-typical interest rate for that currency as a starting point.
Enter it as a percentage or a fixed amount — both fields stay in sync. Watch the hint below the field: below 20% down, PMI will automatically apply in the calculation.
Select 10, 15, 20, or 30 years and enter your quoted annual rate, or use the pre-filled regional typical-range hint if you don't have a lender quote yet.
Fill in property tax rate, home insurance, PMI rate, and HOA fee under "Include Taxes & Costs," then open "+ More Options" to set annual cost increases and any extra monthly, yearly, or one-time payments toward principal.
Review your Total Monthly Payment, Loan Amount, Total Interest, and Payoff Date, along with a monthly breakdown chart, a year-wise principal-vs-interest chart, and a full amortization schedule with real dates.
A realistic PITI calculation using this calculator's default 30-year home price and rate settings
Suppose you're buying a $400,000 home with a 10% down payment ($40,000), leaving a $360,000 loan, at a 6.8% annual interest rate over a 30-year (360-month) term. Property tax runs 1.1%/yr, home insurance is $1,400/yr, and since the down payment is under 20%, PMI applies at 0.5%/yr.
Explanation: Over the full 30-year term with no extra payments, this loan's principal & interest alone totals $845,167 — $485,167 of that is interest, roughly 135% of the amount borrowed. That's the cost of stretching repayment over three decades, and it's why the extra-payment tools matter.
Extra payment effect: Applying the same formula with an Extra Monthly Pay of $200 (equivalent to paying $2,547.13/month toward principal & interest) shows the loan paid off in roughly 286 months instead of 360 — about 6 years 2 months early — cutting total interest from $485,167 to roughly $367,500, a saving of about $117,700, for $200/month in extra payments.
Is your total monthly payment a comfortable share of your income?
A widely cited affordability rule of thumb is the front-end housing ratio — your total monthly PITI (plus HOA) divided by your gross monthly income. It's a general guideline, not a rule your lender is required to follow, but it's a useful gut-check.
| Housing Payment ÷ Gross Monthly Income | General Read | Typical Context |
|---|---|---|
| Under 28% | Comfortable | Within the traditional "28/36 rule" most lenders reference |
| 28% – 36% | Common but tighter | Many buyers in high-cost markets land here |
| Over 36% | Stretched | Higher risk of budget strain; may limit loan approval odds |
For buyers: if your Total Monthly Payment result pushes past 36% of gross income, consider a larger down payment (which also removes PMI below 20%), a longer term, or a lower price range before committing. Use the Paycheck / Salary Calculator to confirm your actual gross and take-home income.
PMI as a cost signal: if PMI shows up in your results, it's a direct signal your equity is below 20% — worth tracking, since it's pure added cost with no equity benefit until it's removed.
Risk considerations: this calculator assumes a fixed rate and a steady payment schedule. It doesn't capture rate resets on ARMs, job-loss risk, maintenance costs beyond what you enter as "Other Costs," or PMI automatically dropping off — treat the total-interest figure as a planning estimate, not a guarantee.
A good mortgage rate is generally one at or below the prevailing national average for your loan type, term, and credit profile. The region-typical hints in this calculator — such as 6.5–7.5% for a 30-year US mortgage — are a practical reference point to judge your quote against.
A widely used guideline is the 28/36 rule: keep your total housing payment under roughly 28% of gross monthly income and all debts combined under 36%. Re-run this calculator at different home prices and down payments until your Total Monthly Payment fits comfortably inside that band.
The interest rate is the cost of borrowing the loan balance itself, while the annual percentage rate (APR) adds lender fees and points to reflect the true annualized cost. When comparing offers, the lower APR is usually the better deal even if the quoted interest rates look nearly identical.
An amortized mortgage splits the loan into equal monthly payments, each covering that month's interest plus a growing amount of principal so the balance reaches zero at the end of the term. Fixed-rate loans like the ones this calculator models are fully amortizing, which is why a 30-year loan's payment is the same every month.

Discount points are upfront cash you pay to reduce your interest rate, which pays off only if you keep the loan long enough to reach the break-even point. Divide the points' total cost by your monthly interest savings to find that break-even month, and buy points only if you expect to stay past it.
A fixed-rate mortgage keeps the same interest rate for the full term, giving predictable monthly payments, while an ARM starts with a lower teaser rate that can adjust up or down later. This calculator models fixed-rate loans only — if you're considering an ARM, test the worst-case reset rate to see whether your payment could become unaffordable.
Closing costs are the one-time fees paid when you finalize a mortgage — origination, appraisal, title, and recording fees among them — typically totaling about 2% to 5% of the loan amount. This calculator does not include them in your monthly payment, so plan for them separately on top of your down payment.
