Understanding Mortgage Payments
Principal & Interest (P&I)
Principal = The loan amount you borrowed
Interest = Cost of borrowing money from the lender
Formula: M = P × [r(1+r)^n] / [(1+r)^n-1]
- M = Monthly payment
- P = Principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (years × 12)
PITI (Full Monthly Payment)
Most lenders quote "PITI" which includes:
- 🏠 Principal: Pays down loan balance
- 💰 Interest: Payment to lender
- 🏛️ Property Tax: Paid to local government (1-3% of home value annually)
- 🛡️ Insurance: Homeowners insurance ($1,000-3,000/year typical)
Additional Costs
- 📋 PMI: Private Mortgage Insurance if down payment < 20%
- 🏘️ HOA Fees: Homeowners Association ($50-500/month)
- 🔧 Maintenance: 1-2% of home value annually (not included in payment)
- ⚡ Utilities: Electric, gas, water, internet, trash

Amortization: How Payments Work
Understanding Amortization
Each monthly payment includes principal AND interest, but the split changes over time:
- 📉 Early payments: Mostly interest, little principal
- ⚖️ Middle payments: 50/50 split
- 📈 Later payments: Mostly principal, little interest
Example: $300,000 at 7% for 30 years
| Payment # | Year | Payment | Principal | Interest | Balance |
|---|---|---|---|---|---|
| 1 | 1 | $1,996 | $246 | $1,750 | $299,754 |
| 60 | 5 | $1,996 | $331 | $1,665 | $278,648 |
| 120 | 10 | $1,996 | $455 | $1,541 | $251,035 |
| 180 | 15 | $1,996 | $625 | $1,371 | $214,362 |
| 240 | 20 | $1,996 | $859 | $1,137 | $165,803 |
| 300 | 25 | $1,996 | $1,180 | $816 | $100,467 |
| 360 | 30 | $1,996 | $1,985 | $11 | $0 |
How Much House Can I Afford?
The 28/36 Rule
Lenders typically use this rule:
- 🏠 28% Rule: Housing costs ≤ 28% of gross monthly income
- 💳 36% Rule: Total debt ≤ 36% of gross monthly income
Example: $6,000/month gross income
- Maximum housing payment (PITI): $6,000 × 28% = $1,680/month
- Maximum total debt: $6,000 × 36% = $2,160/month
- If you have $400 car payment: Housing max = $2,160 - $400 = $1,760
Affordable Home Price by Income
| Annual Income | Max Housing (28%) | Affordable Home (20% down) |
|---|---|---|
| $50,000 | $1,167/mo | ~$175,000 |
| $75,000 | $1,750/mo | ~$265,000 |
| $100,000 | $2,333/mo | ~$350,000 |
| $150,000 | $3,500/mo | ~$525,000 |
| $200,000 | $4,667/mo | ~$700,000 |

Frequently Asked Questions
How much is a $300,000 mortgage per month?
At 7% for 30 years: $1,996/month (principal + interest only). Add property tax, insurance, PMI, and HOA for total monthly payment. Full PITI payment typically $2,500-3,000/month depending on location and down payment.
How much house can I afford on $100,000 salary?
Using the 28% rule: ~$350,000 home with 20% down. Monthly payment would be ~$2,333 (28% of $100k/12). Can afford up to ~$400,000 with lower down payment but will pay PMI.
Should I get a 15-year or 30-year mortgage?
15-year if you can afford higher payments (~50% more) and want to save significantly on interest and build equity faster. 30-year if you need lower monthly payments, are a first-time buyer, or want financial flexibility. You can always pay extra on a 30-year to pay it off early.
What is PMI and how do I avoid it?
PMI (Private Mortgage Insurance) protects the lender if you default. Required if down payment < 20%. Costs 0.5-1.5% of loan amount annually ($100-200/month on $300k loan). To avoid: Put 20% down, use piggyback loan (80-10-10), or get VA loan (no PMI ever).
How is mortgage interest calculated?
Interest is calculated monthly on the remaining balance. Formula: Monthly interest = (Balance × Annual Rate) ÷ 12. Example: $300,000 at 7% = ($300,000 × 0.07) ÷ 12 = $1,750 first month. As you pay down principal, interest decreases each month.
What credit score do I need for a mortgage?
Minimum scores: Conventional (620), FHA (580), VA (no minimum but 620+ typical), USDA (640). Best rates: 740+. Every 20-point drop costs ~0.25% higher rate. Improve score before applying by paying down debt and fixing errors.
How much should I put down on a house?
Ideal: 20% to avoid PMI and get best rates. Minimum: 3-3.5% (conventional/FHA). Reality: Most first-time buyers put 5-10% down. VA/USDA loans allow 0% down. Balance down payment size against keeping emergency fund intact.
What is included in my monthly mortgage payment?
Principal & Interest (P&I) goes to lender. May also include: Property tax (escrowed), Homeowners insurance (escrowed), PMI (if < 20% down), HOA fees (if applicable). Full payment called PITI or PITIH (with HOA).
Home Buying Checklist
- ✅ Check credit score (aim for 740+)
- ✅ Save for down payment + closing costs + reserves
- ✅ Get pre-approved (not just pre-qualified)
- ✅ Determine budget using 28/36 rule
- ✅ Compare mortgage rates from 3-5 lenders
- ✅ Understand all costs (PITI, maintenance, utilities)
- ✅ Get home inspection (always!)
- ✅ Review closing disclosure 3 days before closing
💚 Remember: A mortgage is a 15-30 year commitment. Take time to understand all costs, compare options, and choose a payment you can comfortably afford even if income decreases. When in doubt, choose the lower payment with flexibility to pay extra. 🏠
