Your monthly mortgage payment (principal + interest) is determined by three variables: loan amount, interest rate, and loan term. The formula is:
M = P × [r(1+r)^n] / [(1+r)^n – 1]
Where P = principal loan amount, r = monthly interest rate (annual rate ÷ 12), and n = total number of payments (years × 12).
In practice, your total monthly housing cost includes four components (PITI):
- Principal: The portion reducing your loan balance
- Interest: The lender's cost charged on the outstanding balance
- Taxes: Property taxes (typically 0.5–1.5% of home value annually)
- Insurance: Homeowners insurance (~$100–$300/month) + PMI if down payment < 20%
2026 Mortgage Payment Examples
Based on 2026 rate range of 6.5–7.0% for 30-year fixed conventional loans with 20% down:
| Home Price | Down (20%) | Loan Amount | Monthly P&I @ 6.75% | Monthly P&I @ 7.0% |
|---|---|---|---|---|
| $300,000 | $60,000 | $240,000 | $1,557 | $1,597 |
| $400,000 | $80,000 | $320,000 | $2,076 | $2,129 |
| $500,000 | $100,000 | $400,000 | $2,595 | $2,661 |
| $600,000 | $120,000 | $480,000 | $3,114 | $3,194 |
| $750,000 | $150,000 | $600,000 | $3,892 | $3,992 |
These figures are principal and interest only. Add $400–$700/month for taxes and insurance depending on your location and home value. Use our calculator to get your full PITI estimate.
15-Year vs. 30-Year Mortgage: Which Is Right for You?
The term you choose dramatically affects both your monthly payment and total interest paid:
| Loan | Term | Rate | Monthly P&I | Total Interest Paid |
|---|---|---|---|---|
| $400,000 | 30 years | 7.0% | $2,661 | $557,960 |
| $400,000 | 15 years | 6.3% | $3,446 | $220,280 |
The 15-year mortgage saves over $337,000 in interest on this example but requires a payment $785/month higher. The right choice depends on your cash flow, financial goals, and how long you plan to stay in the home.
Down Payment: How Much Do You Really Need?
- 3% down: Conventional loans (Fannie/Freddie) for first-time buyers. PMI required.
- 3.5% down: FHA loans. Available with credit scores as low as 580.
- 5–10% down: Lower PMI cost, more accessible for move-up buyers.
- 20% down: No PMI. Best rate. Most common for repeat buyers.
- 25%+ down: Best rates on jumbo loans.
PMI on a $400,000 home with 10% down typically runs $150–$250/month and drops off automatically at 78% LTV.
Mortgage Rates in 2026: What to Expect
Following the Federal Reserve's rate adjustments, 30-year fixed mortgage rates in 2026 are expected in the 6.25–7.25% range for well-qualified borrowers. Key factors affecting your rate:
- Credit score: 760+ gets best rates; below 700 adds 0.5–1.5%
- Down payment: 20%+ gets best conventional pricing
- Loan type: Conforming vs. jumbo (>$806,500 in 2026 for most areas)
- Points: Paying discount points upfront lowers your rate
- Property type: Investment properties and condos carry rate premiums
How Much House Can You Afford?
Lenders use two key debt ratios:
- Front-end ratio (housing ratio): Monthly PITI ÷ gross monthly income. Guideline: ≤ 28%.
- Back-end ratio (DTI): All monthly debt payments ÷ gross monthly income. Guideline: ≤ 43% for most loans.
Example: At $8,000/month gross income, you can afford up to $2,240/month in housing costs (28%) and up to $3,440/month in total debt payments (43%). Use our home affordability calculator to see how much you qualify for.
Frequently Asked Questions
What is the monthly payment on a $400,000 mortgage?
On a $400,000 30-year fixed mortgage at 6.75% with 20% down ($80,000 down, $320,000 loan), the principal and interest payment is approximately $2,076/month. Adding estimated property taxes ($350/mo) and homeowners insurance ($130/mo) brings total PITI to approximately $2,556/month.
How do I get a lower mortgage rate?
Improve your credit score above 760, make a larger down payment (20%+), shop at least 3–5 lenders, consider buying discount points if you plan to stay 5+ years, and choose a 15-year term if the payment is affordable. Rate locks typically run 30–60 days.
What's the difference between pre-qualification and pre-approval?
Pre-qualification is a quick informal estimate based on self-reported financials — no credit pull, no documentation. Pre-approval involves a hard credit inquiry and verification of income/assets. Pre-approval carries significantly more weight with sellers and is required to make competitive offers in most markets.
