Loan Formulas
Monthly Payment Formula:
M = P × [r(1+r)^n] / [(1+r)^n-1]
Where:
- M = Monthly payment
- P = Principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (years × 12)

Understanding Your Loan Payment
Principal vs. Interest
Each monthly payment includes two parts:
- 💰 Principal: Reduces your loan balance
- 💸 Interest: Cost of borrowing (goes to lender)
Early payments: Mostly interest, small principal reduction
Later payments: Mostly principal, less interest
Why? Interest is calculated on remaining balance. As balance decreases, interest portion shrinks.
Example: $250,000 Loan at 7% for 30 Years
| Payment # | Monthly Payment | Principal | Interest | Balance |
|---|---|---|---|---|
| 1 | $1,663 | $205 | $1,458 | $249,795 |
| 60 (Year 5) | $1,663 | $277 | $1,386 | $232,543 |
| 180 (Year 15) | $1,663 | $513 | $1,150 | $175,545 |
| 300 (Year 25) | $1,663 | $950 | $713 | $85,732 |
| 360 (Final) | $1,663 | $1,654 | $9 | $0 |
Mortgage-Specific Information
What's Included in Your Monthly Payment?
PITI - Principal, Interest, Taxes, Insurance:
- 🏠 Principal & Interest: Loan payment (shown in calculator)
- 🏛️ Property Taxes: Varies by location (1-3% of home value annually)
- 🛡️ Homeowners Insurance: $1,000-$3,000 per year
- 📋 PMI (Private Mortgage Insurance): If down payment < 20%
- 🏘️ HOA Fees: If applicable ($50-$500/month)
Example: $250,000 loan at 7% = $1,663/mo principal + interest. Add $400 taxes + $150 insurance + $100 PMI = $2,313 total monthly housing cost.
Down Payment Impact
| Home Price | Down Payment | Loan Amount | Monthly P&I | PMI |
|---|---|---|---|---|
| $300,000 | 3% ($9,000) | $291,000 | $1,936 | ~$145/mo |
| $300,000 | 10% ($30,000) | $270,000 | $1,797 | ~$135/mo |
| $300,000 | 20% ($60,000) | $240,000 | $1,597 | $0/mo |
Key insight: 20% down payment eliminates PMI, saving $100-200/month!
15-Year vs. 30-Year Mortgage
Example: $250,000 loan at 7% interest
| Term | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|
| 30 years | $1,663 | $348,772 | $598,772 |
| 15 years | $2,247 | $154,393 | $404,393 |
Savings with 15-year: $194,379 in interest! But monthly payment is $584 higher.
Auto Loan Information
New vs. Used Car Loan Rates
- 🚗 New cars: Lower rates (5-7%), longer terms (up to 84 months)
- 🚙 Used cars: Higher rates (6-10%), shorter terms (up to 72 months)
- 💳 Credit score matters: 750+ = best rates, below 600 = much higher
Car Loan Example: $30,000 at Different Terms

How to Lower Your Interest Rate
- 📈 Improve credit score: Pay bills on time, reduce debt-to-income ratio
- 💰 Larger down payment: More equity = lower risk for lender
- ⏰ Shorter loan term: 15-year vs 30-year often gets lower rate
- 🏦 Shop around: Compare 3-5 lenders (rates vary by 0.5-1%)
- 💳 Pay points: Upfront fee to "buy down" your rate
- 🤝 Add a co-signer: Someone with good credit co-signs
- 💼 Show stable income: 2+ years same job = better rates
Strategies to Pay Off Loans Faster
1. Make Extra Payments
Example: $250,000 mortgage at 7% for 30 years
- Standard payment: $1,663/month = $348,772 interest
- Add $100/month extra: Pay off in 25.7 years, save $69,391 interest
- Add $500/month extra: Pay off in 17.4 years, save $161,742 interest
2. Make Bi-Weekly Payments
Pay half your monthly payment every 2 weeks = 26 half-payments = 13 full payments per year (instead of 12)
Result: One extra payment per year, pay off 30-year loan in ~26 years
3. Refinance to Lower Rate
If rates drop 1% or more, refinancing can save thousands:
Example: $250,000 loan at 7%, refinance to 6%
- Before: $1,663/month
- After: $1,499/month
- Monthly savings: $164
- Total savings over 30 years: ~$59,000 (minus refinance costs)
4. Round Up Payments
If payment is $1,663, pay $1,700. Small difference, big impact over time.
Frequently Asked Questions
How is my monthly loan payment calculated?
Monthly payment = Principal × [r(1+r)^n] / [(1+r)^n-1], where r = monthly interest rate and n = number of payments. Each payment includes both principal (reduces loan) and interest (cost of borrowing).
How much can I afford to borrow?
General rule: Your total monthly debt payments (including the new loan) should not exceed 36% of your gross monthly income. For mortgages, total housing costs should stay under 28% of gross income.
Should I choose a 15-year or 30-year mortgage?
15-year: Higher monthly payment, much less total interest, build equity faster, better rate. 30-year: Lower monthly payment, more flexibility, but pay significantly more interest over life of loan. Choose based on your budget and financial goals.
What's a good interest rate?
It depends on loan type and credit score. Mortgages: 6-7% is typical (2024). Auto loans: 5-8% for new, 6-10% for used. Personal loans: 8-15% with good credit. Always shop around and compare at least 3-5 lenders.
How much will I pay in total interest?
Total interest = (Monthly payment × Number of payments) - Principal. For a $250,000, 30-year mortgage at 7%, you'll pay ~$348,772 in interest - that's 139% of the original loan amount!
Can I pay off my loan early?
Most loans allow early payoff, but check for prepayment penalties. Making extra payments saves interest and shortens loan term. Even small extra payments ($50-100/month) can save thousands over the life of the loan.
What is an amortization schedule?
An amortization schedule shows every payment over the life of your loan: how much goes to principal, how much to interest, and your remaining balance after each payment. Early payments are mostly interest; later payments are mostly principal.
What credit score do I need for a good rate?
Excellent (750+): Best rates. Good (700-749): Competitive rates. Fair (650-699): Higher rates. Poor (below 650): Significantly higher rates or may not qualify. Improve credit score before applying for best rates.
When to Consider Refinancing
Refinance if:
- ✅ Interest rates drop 1% or more below your current rate
- ✅ Your credit score has improved significantly (50+ points)
- ✅ You want to switch from adjustable-rate to fixed-rate
- ✅ You want to shorten your loan term (30-year to 15-year)
- ✅ You have 15+ years left on your mortgage
Don't refinance if:
- ❌ You plan to move within 2-3 years (won't recoup closing costs)
- ❌ Closing costs exceed potential savings
- ❌ You're close to paying off the loan (less than 5 years left)
