Understanding Your Mortgage
What's Included in Your Payment?
PITI: Principal, Interest, Taxes, and Insurance make up your base payment. Many lenders also require PMI if you put down less than 20%.
Down Payment Impact
Putting down 20% or more eliminates PMI (Private Mortgage Insurance), which can save you $100-300/month. However, a smaller down payment helps you buy sooner.
15 vs 30 Year Terms
30-year: Lower monthly payments, more total interest.
15-year: Higher monthly payments, less total interest, build equity faster.
Tips for Home Buyers
- Aim for a payment under 28% of gross income
- Get pre-approved before house hunting
- Shop multiple lenders for best rates
- Consider total cost, not just monthly payment
Frequently Asked Questions
This calculator helps you explore different home price scenarios and understand what you can afford based on your budget. The Mortgage Payment Calculator is designed for when you already know your target home price and want to understand your exact monthly payment breakdown, total loan cost, and the impact of extra payments. Use this tool for planning and exploration, then use the Payment Calculator for detailed payment analysis.
While 20% down is ideal to avoid PMI, many buyers put down 3-10% to get into a home sooner. The key is balancing your down payment with maintaining an emergency fund and other financial goals. A larger down payment means lower monthly payments and less interest paid over time.
A 30-year mortgage offers lower monthly payments and more flexibility, making it easier to qualify and manage cash flow. A 15-year mortgage builds equity faster and saves significantly on interest, but requires higher monthly payments. Choose based on your budget, financial goals, and how long you plan to stay in the home.
Private Mortgage Insurance (PMI) is required when you put down less than 20%. It typically costs 0.5-1% of the loan amount annually. You can avoid PMI by putting down at least 20%, using a piggyback loan (80-10-10), or choosing a lender-paid PMI option. PMI automatically drops off once you reach 20% equity through payments or home value appreciation.
The 28/36 rule is a guideline lenders use to determine how much you can afford. It states that your monthly housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income, and your total debt payments (housing plus car loans, student loans, credit cards) should not exceed 36%. For example, with a $6,000 gross monthly income, aim for housing costs under $1,680 and total debt under $2,160.
Property taxes and homeowners insurance are typically collected monthly by your lender as part of your escrow payment, adding $300-$800 or more to your monthly bill depending on location. Property taxes vary widely by state and county, usually ranging from 0.5% to 2.5% of your home's assessed value annually. Homeowners insurance averages $1,000 to $3,000 per year. Together, these costs can add 20-40% on top of your principal and interest payment, so it is important to factor them into your budget.

Mortgage Prepayment Strategies: Save Thousands in Interest
Paying off your mortgage early can save you tens of thousands of dollars in interest and help you achieve financial freedom sooner. This comprehensive guide covers prepayment strategies, calculations, and considerations to help you decide if prepayment is right for you.
1. How Mortgage Prepayment Works
When you make extra payments on your mortgage, the additional amount goes directly toward reducing your principal balance. Unlike regular payments where most goes to interest early in the loan, extra payments are 100% principal reduction.
Key Benefits of Prepayment
- Reduces total interest paid: Less principal means less interest accrues each month
- Shortens loan term: You pay off the loan faster without refinancing
- Builds equity faster: More of your home is "yours" sooner
- No penalty for most loans: FHA, VA, and most conventional loans have no prepayment penalties
2. Prepayment Strategies
Lump Sum Payments
Making one-time large payments when you receive extra money can significantly reduce your loan balance.
- Sources: Tax refunds, work bonuses, inheritance, investment gains
- Best timing: Early in the loan when interest portion is highest
- Example: A $10,000 lump sum in year 1 of a $300,000 loan at 7% saves approximately $23,000 in total interest
Extra Monthly Payments
Adding a fixed amount to each monthly payment creates consistent principal reduction.
- Predictable impact: Easy to budget and track progress
- Flexibility: Adjust amount based on financial situation
- Example: Adding $100/month to a $300,000 loan at 7% saves over $80,000 in interest and pays off 5 years early
Bi-weekly Payments
Paying half your monthly payment every two weeks results in 26 half-payments (13 full payments) per year instead of 12.
- How it works: 52 weeks / 2 = 26 payments / 2 = 13 full payments
- Extra payment: You make one extra full payment per year automatically
- Example: On a $300,000 loan at 7%, bi-weekly payments save approximately $60,000 in interest and pay off 4.5 years early
3. Interest Savings Comparison
The following table shows how different prepayment strategies affect a $300,000 mortgage at 7% interest over 30 years.
| Scenario | Monthly Payment | Total Interest | Time Saved | Interest Saved |
|---|---|---|---|---|
| Standard 30-year | $1,996 | $418,527 | 0 | $0 (baseline) |
| +$100/month extra | $2,096 | $337,234 | 5 years | $81,293 |
| +$200/month extra | $2,196 | $278,445 | 8 years | $140,082 |
| +$500/month extra | $2,496 | $183,621 | 13 years | $234,906 |
| Bi-weekly payments | $998 x 26/yr | $359,867 | 4.5 years | $58,660 |
4. Prepayment Penalty Considerations
Before making extra payments, verify your loan terms allow prepayment without penalties.
Loans Typically WITHOUT Prepayment Penalties
- FHA loans: Federal law prohibits prepayment penalties
- VA loans: No prepayment penalties allowed
- USDA loans: No prepayment penalties
- Most conventional loans after 2014: QM rules limit prepayment penalties
Loans That MAY Have Penalties
- Some conventional loans (pre-2014): May have penalties in first 3-5 years
- Non-QM loans: May include prepayment restrictions
- Investment property loans: More likely to have prepayment clauses
How to Check Your Loan
- Review your original loan documents for "prepayment clause" or "prepayment penalty"
- Check your Closing Disclosure form (page 4)
- Call your loan servicer to confirm prepayment terms
- Ask specifically about partial prepayment vs. full payoff penalties
5. When Prepayment Makes Sense
Prepaying your mortgage is not always the optimal financial choice. Consider these factors:
Prepayment IS a Good Idea When
- Your mortgage rate is higher than expected investment returns (after tax)
- Being debt-free is an important personal goal
- You're approaching retirement and want lower fixed costs
- You have a fully-funded emergency fund (3-6 months expenses)
- You've maxed out tax-advantaged retirement accounts
- You sleep better with less debt
Consider Alternatives First When
- You have high-interest debt (credit cards, personal loans)
- You lack an emergency fund
- You're not capturing employer 401(k) match
- Your mortgage rate is low (below 4-5%)
- You need liquidity for other goals
- You could earn higher returns investing elsewhere
The Math: Prepayment vs. Investing
Consider your after-tax mortgage rate vs. expected investment returns:
- If you itemize deductions: Effective mortgage rate = Rate x (1 - tax bracket). At 7% rate and 24% bracket = 5.32% effective rate
- If you take standard deduction: Your effective rate equals your actual rate (no deduction benefit)
- Stock market average: S&P 500 historically returns approximately 10% annually (before taxes and fees)
6. Alternatives to Prepayment
Before accelerating mortgage payments, ensure you've addressed these financial priorities:
Higher Priority Financial Goals
- Pay off high-interest debt: Credit cards (15-25% APR) and personal loans should be paid first
- Build emergency fund: 3-6 months of essential expenses in accessible savings
- Capture employer 401(k) match: This is 50-100% instant return on your contribution
- Max tax-advantaged accounts: 401(k), IRA, HSA offer tax benefits that mortgages don't
Investment Alternatives
- Taxable brokerage account: If mortgage rate is low, investing may yield higher long-term returns
- I-bonds: Currently offering inflation protection with tax advantages
- High-yield savings: Provides liquidity with competitive rates (4-5% as of February 2026)
Balanced Approach
Many financial advisors recommend a hybrid strategy:
- Make small extra payments to reduce mortgage term modestly
- Invest the majority of extra funds for potentially higher returns
- Maintain flexibility to adjust based on market conditions and personal circumstances
