Mortgage Payment — The Full PITI Picture
The amortization formula gives only principal and interest. Your real monthly payment adds property taxes, insurance, and — below 20% equity — PMI, which protects the lender, not you. Escrow accounts bundle these so you pay one number; the calculator's tax/insurance fields reproduce the PITI total.
Rate matters more than price at long terms: on $400k at 6.5% for 30 years, P&I ≈ $2,528. At 5.5%, ≈ $2,271 — $257/month, $92,000 over the loan. Points (1 point = 1% of loan prepaid) buy rate down; the break-even is usually 4-6 years of ownership.
Worked Example: $400,000 Home, 20% Down, 6.5%, 30 Years
Loan: $320,000; r = 6.5%/12 = 0.5417%; n = 360
P&I = 320,000 × [0.005417 × 1.005417^360] ÷ [1.005417^360 − 1] ≈ $2,022.62
+ taxes $500/mo + insurance $120/mo (no PMI at 20% down)
Total PITI ≈ $2,642.62 — and the first payment includes only ≈ $289 of principal
Interest over 30 years: $2,022.62 × 360 − 320,000 ≈ $408,143
You'd pay back more in interest than the house cost. One extra payment per year (biweekly schedule) cuts ~6 years and ~$95k of interest — principal prepayment early in the loan is worth the most.
Frequently Asked Questions
How much house can I afford?
Lenders cap housing cost at 28% of gross income and total debts at 36-43% (DTI). On $100k income: ≈ $2,333/month housing max. Better rule: keep PITI under 25% of gross so maintenance (1-2%/yr of home value) and life don't squeeze you.
15-year or 30-year mortgage?
15-year rates run ~0.75-1% lower and the same $320k loan costs ≈ $2,712/month but only ≈ $168k total interest vs $408k. Choose 30-year for cash flow flexibility and invest the difference only if you actually will — the guaranteed 6.5% 'return' of paying off early beats most investing for risk-averse households.
When should I refinance?
Classic rule: refinance when the new rate is ≥0.75-1% lower and you'll stay past the break-even (closing costs ÷ monthly savings — typically $2,500-5,000 costs ÷ $200+ savings ≈ 1-2 years). Also refinance to drop PMI, switch ARM→fixed, or shorten the term.
How does PMI disappear?
At 22% equity it auto-terminates (conventional loans, current on payments); you can REQUEST removal at 20% based on the original schedule, or earlier with a new appraisal showing 20% equity. FHA loans keep MIP for the life of the loan unless you refinance to conventional.

TL;DR
Navigate the 2026 housing market with our guide on 85% vs 90% LTV mortgages, DSCR loans, and exact input calculations.
With US 30-year rates stabilizing at 6.23%, many first-time buyers are re-engaging with high-LTV loans. This page helps you:
- Identify your monthly payment including PMI and escrow.
- Compare 85% vs. 90% LTV deposit requirements.
- Calculate your 'Homeownership Freedom Number.'
Explain Your Inputs: Why We Need This Data
We need specific details to avoid misleading defaults:
- Home Price & Down Payment: Determines your exact Loan-to-Value (LTV) ratio.
- Interest Rate: Crucial for amortization. We default to the 2026 average of 6.23%.
- Loan Term: A 30-year term offers lower payments, while a 15-year term builds equity faster.
Interpretation Guide: Actionable Context
A result of $2,800/month might seem high, but in 2026, lenders look for a Debt-to-Income (DTI) ratio below 36%.
- If your result is < 28% of your income: You are in the 'Green Zone' for approval.
- If your result is > 36%: Consider our Asset-Based Calculator for non-traditional income streams.
Explainable Logic: The Math Behind the Tool
We don't just give you a number; we show the math. Your payment is calculated using the Standard Amortization Formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ] Why we need your zip code: Property taxes vary wildly. We use local 2026 averages to ensure you aren't hit with a 'misleading default' error common on legacy sites.
People Also Ask (PAA)
What is a good biological age vs chronological age? While unrelated to mortgages, a good biological age is lower than your chronological age. For financial health, a good 'financial age' means your net worth is growing faster than your debt.
Can I get a mortgage with an 85% LTV in 2026? Yes, 85% LTV mortgages are widely available in 2026. They require a 15% down payment and typically mandate Private Mortgage Insurance (PMI) until you reach 20% equity.
What is the difference between an 85% and 90% LTV mortgage? A 90% LTV requires only a 10% down payment but usually comes with higher PMI premiums and slightly higher interest rates compared to an 85% LTV loan.
