How Much Down Payment Do You Need?

March 15, 2026 8 min read Home Buying

One of the biggest questions home buyers ask: "How much should I put down?" The answer isn't one-size-fits-all. Let's break down your options and their financial impact.

Minimum Down Payment Requirements

Loan Type Minimum Down PMI Required
Conventional3%Yes, if below 20%
FHA3.5%Yes, for 11 years if 10%+
VA0%No
USDA0%Yes

What is PMI?

Private Mortgage Insurance (PMI) protects the lender if you default. It typically costs 0.5% to 1% of your loan amount annually.

On a $300,000 home with 5% down ($15,000):

  • Loan amount: $285,000
  • PMI at 0.8%: ~$2,280/year or $190/month
  • PMI until you reach 20% equity (can be 7-10+ years)

The 20% Rule

Putting down 20% or more:

  • Avoids PMI entirely
  • Lower monthly payment
  • More equity from day one
  • Better loan terms (lower rates sometimes)

Example: $400,000 Home

5% Down ($20,000)

Monthly: ~$2,400

PMI: ~$190/month

Total Monthly: ~$2,590

20% Down ($80,000)

Monthly: ~$2,200

PMI: $0

Total Monthly: ~$2,200

When to Put Less Down

  • Market is rising fast: Buy now, build equity quickly
  • Low-interest environment: Keep cash invested
  • Diversity of investments: Stocks may outperform
  • Preserving emergency fund: Don't drain savings

When to Put More Down

  • High PMI cost: Eliminating it saves money
  • Lower credit score: Larger down payment helps
  • Stable job/income: More security
  • Want lower payments: Stretching affordability

Key Takeaways

  1. 3-5% is the minimum, but 20% avoids PMI
  2. PMI costs thousands over the life of a loan
  3. Don't drain your emergency fund for a larger down payment
  4. Consider opportunity cost of cash vs investment returns
  5. Run the numbers on mortgage calculators
