Understanding Down Payments
A down payment is the initial cash payment you make when purchasing a home. It represents your equity stake in the property and affects your loan terms, monthly payment, and overall borrowing costs.
Why down payments matter:
- Lower loan amount: Borrow less, pay less interest
- Better interest rates: Larger down payments often qualify for lower rates
- Avoid PMI: 20% down eliminates private mortgage insurance
- Instant equity: Protection against market downturns
- Stronger offer: Sellers prefer buyers with larger down payments
Typical down payment amounts:
- Conventional loans: 5-20% (3% minimum for some programs)
- FHA loans: 3.5% minimum
- VA loans: 0% for eligible veterans
- USDA loans: 0% in eligible rural areas
Down Payment Calculations
Essential formulas for planning your down payment:
Down Payment Formulas
Where:
- Loan Amount= Home Price - Down Payment
- LTV= Loan-to-Value ratio = (Loan Amount / Home Price) × 100
- Equity= Home Value - Loan Balance
Private Mortgage Insurance (PMI)
What is PMI?
PMI protects the lender if you default on your mortgage. It's required when your down payment is less than 20%.
PMI costs:
- Typically 0.5% - 1% of loan amount annually
- $100-$300/month on a $300,000 loan
- Added to monthly mortgage payment
How to remove PMI:
- Automatically removed at 78% LTV (loan balance vs. original value)
- Request removal at 80% LTV with good payment history
- Refinance when you reach 20% equity
- Home appreciation may help you reach 20% faster
Example PMI cost:
- Home price: $400,000
- Down payment: 10% ($40,000)
- Loan: $360,000
- PMI at 0.8%: $240/month
- Over 5 years until 20% equity: $14,400

Down Payment by Loan Type
Conventional Loans:
- Minimum: 3% (Fannie Mae HomeReady, Freddie Mac Home Possible)
- Standard: 5-10%
- Ideal: 20% (avoids PMI)
- PMI required below 20%
FHA Loans:
- Minimum: 3.5% with 580+ credit score
- 10% required with 500-579 credit score
- MIP (Mortgage Insurance Premium) required for life of loan
- Good for lower credit scores
VA Loans (Veterans):
- 0% down payment option
- No PMI required
- VA funding fee applies (can be financed)
- Must be eligible veteran or active military
USDA Loans:
- 0% down payment in eligible rural areas
- Income limits apply
- Guarantee fee required (can be financed)
- Good option for rural homebuyers
Strategies to Save for Down Payment
Calculate your savings target:
- Home price target × down payment percentage
- Add 3-5% for closing costs
- Add moving expenses and initial home costs
Savings strategies:
- Automate savings: Set up automatic transfers to dedicated account
- High-yield savings: Earn 4-5% APY while saving
- Budget cuts: Reduce expenses temporarily to accelerate savings
- Side income: Extra jobs or selling unused items
- Windfall allocation: Tax refunds, bonuses, gifts toward down payment
Down payment assistance programs:
- State and local first-time buyer programs
- Employer assistance programs
- FHA down payment assistance
- Grants for specific professions (teachers, first responders)
Gift funds:
- Family gifts allowed for most loan types
- Gift letter required documenting no repayment expected
- Some loans require minimum borrower contribution
Should You Put 20% Down?
Advantages of 20% down:
- No PMI saves $100-300+/month
- Lower monthly payment
- More equity from day one
- Often better interest rates
- Stronger offer in competitive markets
When less than 20% may make sense:
- Home prices rising faster than you can save
- Would deplete emergency fund
- Opportunity cost of tying up cash
- First-time buyer programs with low rates
- Strong investment returns elsewhere
Break-even analysis:
Compare PMI cost vs. opportunity cost of larger down payment. If you could earn 7% investing vs. paying 0.8% PMI, the math might favor lower down payment.
Bottom line:
20% down is ideal but not required. The best down payment is one that lets you buy comfortably while maintaining emergency savings and not stretching your budget.
Worked Examples
Standard 20% Down Payment
Problem:
Calculate down payment and loan for a $450,000 home with 20% down.
Solution Steps:
- 1Home price: $450,000
- 2Down payment percentage: 20%
- 3Down payment: $450,000 × 0.20 = $90,000
- 4Loan amount: $450,000 - $90,000 = $360,000
- 5LTV ratio: 80%
- 6PMI: Not required (20%+ down)
Result:
Down payment: $90,000. Loan amount: $360,000. No PMI required, saving approximately $200/month.
Low Down Payment with PMI
Problem:
Calculate costs for $350,000 home with 5% down at 0.8% PMI rate.
Solution Steps:
- 1Home price: $350,000
- 2Down payment: 5% = $17,500
- 3Loan amount: $332,500
- 4LTV: 95%
- 5Annual PMI: $332,500 × 0.008 = $2,660
- 6Monthly PMI: $222
- 7PMI until ~80% LTV (about 7-10 years)
Result:
Down payment: $17,500. Monthly PMI: ~$222. Lower entry but higher monthly cost until equity builds.
Comparing Down Payment Options
Problem:
Compare 10% vs 20% down on $400,000 home. Which is better?
Solution Steps:
- 110% down: $40,000 down, $360,000 loan
- 2PMI at 0.7%: $210/month for ~8 years = $20,160
- 320% down: $80,000 down, $320,000 loan
- 4No PMI, $40,000 more cash tied up
- 5Monthly payment difference: ~$200 + $210 PMI = $410
- 6Opportunity cost of extra $40,000 at 5%: $2,000/year
Result:
20% down saves ~$20,160 in PMI but requires $40,000 more upfront. If you can afford it without draining savings, 20% is usually better.
