A mortgage turns a home price into a long-term payment plan, so the number that matters most is the monthly cost you can carry without crowding out savings, repairs, and other bills. Use the calculator above to compare price, down payment, rate, term, taxes, insurance, HOA dues, and PMI before you treat a listing price as affordable.
Beyond principal and interest, your monthly payment typically includes property taxes and homeowners insurance, held in an escrow account by your lender. If your down payment is less than 20%, you'll also pay Private Mortgage Insurance (PMI) until you reach 20% equity.
Example: $350,000 Home with 20% Down at 6.5%
Over 30 years, you'll pay more in interest than the original loan amount!
The Mortgage Payment Formula
M = P × [r(1+r)n] / [(1+r)n - 1]
Types of Mortgages Compared
| Mortgage Type | Best For | Down Payment | Key Features |
|---|---|---|---|
| Conventional | Good credit, stable income | 3-20% | PMI required if <20% down |
| FHA | First-time buyers, lower credit | 3.5% | Requires mortgage insurance for life |
| VA | Veterans, active military | 0% | No PMI, competitive rates |
| USDA | Rural homebuyers | 0% | Income limits apply |
| Jumbo | High-value properties | 10-20% | For loans above conforming limits |
Current Mortgage Rate Context
Mortgage rates change daily and are influenced by Federal Reserve policy, inflation expectations, and demand for mortgage-backed securities in bond markets. When the Fed raises its benchmark rate, mortgage rates typically follow — and vice versa. Rates also vary by loan type, credit score, down payment size, and the individual lender's pricing.
| Era | Approximate Rate Range | What Drove It |
|---|---|---|
| 1980s peak | 10–18%+ | Fed fighting double-digit inflation |
| 2010–2021 low-rate era | 3–5% | Post-crisis stimulus, subdued inflation |
| Post-2022 rate-hike era | 6–8% | Fed combating post-pandemic inflation |

30-Year vs. 15-Year Mortgage: Complete Comparison
The loan term dramatically affects both your monthly payment and total interest paid:
$280,000 Loan at 6.5% Interest
| Factor | 30-Year | 15-Year |
|---|---|---|
| Monthly Payment | $1,770 | $2,440 |
| Total Interest | $357,358 | $159,222 |
| Interest Savings | - | $198,136 saved! |
Pro Tip: Best of Both Worlds
Take a 30-year mortgage for the lower required payment, but pay extra toward principal each month as if it were a 15-year loan. This gives you flexibility if finances get tight, while still reducing interest if you stay on track.
Mortgage Payment Breakdown: Principal vs. Interest by Year
Because mortgage payments are fixed, each payment is split between interest and principal in a shifting ratio called amortization. Early in the loan, most of each payment covers interest on the outstanding balance. As the balance falls, the interest charge drops and more of the fixed payment chips away at principal — a process that accelerates dramatically in the final years.
This front-loaded structure is why extra principal payments made in the first few years have such a powerful effect on total interest paid and payoff date.
| Loan Year | Principal / Mo | Interest / Mo | P&I Payment |
|---|---|---|---|
| Year 1 | ~$558 | ~$2,312 | ~$2,661 |
| Year 5 | ~$648 | ~$2,013 | ~$2,661 |
| Year 10 | ~$804 | ~$1,857 | ~$2,661 |
| Year 20 | ~$1,238 | ~$1,423 | ~$2,661 |
| Year 30 (final) | ~$2,640 | ~$21 | ~$2,661 |
Based on a $400,000 loan at 7% interest, 30-year fixed. The monthly P&I payment is constant; the split between principal and interest shifts every month throughout the loan.
Understanding PMI (Private Mortgage Insurance)
PMI protects the lender (not you) if you default on your loan. It's required when your down payment is less than 20% of the home's value.
- Cost: Typically 0.3% to 1.5% of the original loan amount annually
- On a $280,000 loan: $70-$350/month
- Removal: Request removal at 20% equity; automatic at 22%
- Exception: FHA loans require mortgage insurance for the life of the loan
How to Eliminate PMI Faster
Make extra principal payments to reach 20% equity sooner. Some lenders also allow you to pay for a new appraisal if home values have increased significantly, potentially qualifying you for PMI removal earlier.
How Much House Can You Afford?
Lenders use two key ratios to determine how much you can borrow:
Front-End Ratio (Housing Ratio)
Your total housing payment (PITI + HOA) should not exceed 28% of your gross monthly income. Example: If you earn $8,000/month, keep housing costs under $2,240.
Back-End Ratio (Total DTI)
All monthly debt payments (housing + car loans + credit cards + student loans) should not exceed 36-43% of gross income. Some lenders allow up to 50% for strong borrowers.
Emergency Fund First
Before buying, ensure you have 3-6 months of expenses saved beyond your down payment and closing costs. Home ownership comes with unexpected repairs!
The 28/36 Rule at a Glance
| Annual Income | Max Housing Payment (28%) | Max Mortgage Amount (approx. at 7%) | Max Total Debt (36%) |
|---|---|---|---|
| $60,000 | ~$1,400/mo | ~$210,000 | ~$1,800/mo |
| $80,000 | ~$1,867/mo | ~$280,000 | ~$2,400/mo |
| $100,000 | ~$2,333/mo | ~$350,000 | ~$3,000/mo |
| $120,000 | ~$2,800/mo | ~$420,000 | ~$3,600/mo |
Max mortgage amounts are estimates based on P&I only at 7% for 30 years. Add property taxes, insurance, and HOA before checking your payment against the 28% ceiling.
Hidden Costs of Homeownership
Beyond your mortgage payment, budget for:
- Maintenance: 1-2% of home value annually ($3,500-$7,000 for a $350K home)
- Utilities: Often higher than renting (larger space, yard watering)
- Closing Costs: 2-5% of loan amount ($5,600-$14,000 on $280K loan)
- Moving Expenses: $1,000-$5,000+ depending on distance
7 Strategies to Lower Your Mortgage Payment
Improve Your Credit Score
A score of 760+ typically gets the best rates. Each 20-point improvement can save 0.125-0.25% on your rate, saving thousands over the loan term.
Increase Your Down Payment
Every additional percent down reduces your loan amount and monthly payment. Hitting 20% eliminates PMI entirely.
Shop Multiple Lenders
Get quotes from at least 3-5 lenders. Rates can vary by 0.5% or more, which translates to tens of thousands over 30 years.
Buy Discount Points
Paying 1% of the loan upfront typically reduces your rate by 0.25%. Worth it if you'll stay in the home 4+ years.
Choose a Shorter Loan Term
15-year mortgages typically have rates 0.5-0.75% lower than 30-year mortgages.
Consider an ARM
Adjustable-rate mortgages offer lower initial rates. Good if you plan to move or refinance within 5-7 years.
Appeal Your Property Tax
If similar homes are assessed lower, appeal your assessment. Successful appeals can save hundreds annually.
Frequently Asked Questions
With a $100,000 salary, using the 28% front-end ratio, you could afford approximately $2,333/month in housing costs. At 6.5% interest with 20% down, this translates to a home price around $350,000-$400,000, depending on property taxes and insurance in your area. Always factor in your other debts and lifestyle expenses.
Conventional loans: Minimum 620, but 740+ gets the best rates. FHA loans: Minimum 580 with 3.5% down, or 500 with 10% down. VA loans: No minimum, but most lenders require 620+. Every 20 points above 620 typically improves your rate by 0.125%.
It depends on your situation. Putting 20% down eliminates PMI, saving $100-300/month. However, don't deplete your emergency fund. A good rule: put down enough to avoid PMI while keeping 6 months of expenses in savings. If you can't do both, consider a smaller down payment and paying PMI temporarily.
Consider your mortgage rate vs. investment returns. At 3-4% mortgage rate, investing in index funds (historical ~10% return) may build more wealth. At 6-7%+ rates, paying off the mortgage provides a guaranteed "return" equal to your rate. Also prioritize: max out 401k match first, pay off high-interest debt, then consider extra mortgage payments.
Extra payments go directly to principal, dramatically reducing total interest. Example: On a $280,000 loan at 6.5%, paying an extra $200/month saves $87,000 in interest and pays off the loan 7 years early. Even one extra payment per year (bi-weekly payments) can shave 4-5 years off a 30-year mortgage.
Pre-qualification: A quick estimate based on self-reported information. Takes minutes, no credit check. Pre-approval: A formal commitment from a lender after reviewing your credit, income, and assets. Takes 1-3 days, involves a hard credit inquiry. Sellers prefer pre-approved buyers as it shows you're serious and financially qualified.
The old rule was "refinance if rates drop 1%," but consider: (1) Closing costs are typically 2-5% of the loan, (2) Calculate your break-even point (costs ÷ monthly savings), (3) Refinance if you'll stay past break-even. Also consider refinancing to remove PMI, switch from ARM to fixed, or tap equity (though HELOCs may be cheaper for the latter).
Closing costs typically range from 2-5% of the loan amount and include: appraisal ($300-700), title insurance ($1,000-3,000), origination fees (0.5-1%), escrow deposits, and recording fees. Buyers usually pay most closing costs, but you can negotiate seller concessions (seller pays up to 3-6% of closing costs) in buyer's markets.
The standard amortization formula is: M = P[r(1+r)n] / [(1+r)n − 1], where P is the principal (loan amount), r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments (loan term in years × 12). For example, a $300,000 loan at 7% for 30 years has r = 0.07/12 ≈ 0.005833 and n = 360, yielding a monthly P&I of about $1,996.
A full mortgage payment is often called PITI: Principal (reducing your loan balance), Interest (cost of borrowing), Taxes (property taxes held in escrow), and Insurance (homeowners insurance, also escrowed). If your down payment is under 20% on a conventional loan, you'll also pay PMI (Private Mortgage Insurance), typically $50–200/month. HOA fees are separate but add to your total monthly housing cost.
Down payment requirements depend on loan type: Conventional loans allow as little as 3%, though 20% eliminates PMI. FHA loans require 3.5% (or 10% if your credit score is 500–579). VA and USDA loans offer 0% down for eligible borrowers. Down payments under 20% on conventional loans typically add PMI of $50–200/month until you reach 20% equity. A larger down payment also reduces your loan amount and total interest paid.
A 15-year mortgage has a higher monthly payment but a lower interest rate (typically 0.5–0.75% less than a 30-year) and dramatically less total interest paid — often 50%+ savings over the life of the loan. Equity builds much faster. A 30-year mortgage offers a lower required monthly payment and more cash-flow flexibility, but you'll pay significantly more in interest over time. A common strategy: take the 30-year for payment flexibility, but make extra principal payments each month to capture much of the interest savings.
