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.
