How Much Down Payment Do You Need?
A down payment is the upfront cash you pay toward the purchase price of a home, with the remainder financed through a mortgage loan. While the traditional guideline is 20% down, most buyers today put down far less. According to the Consumer Financial Protection Bureau (cfpb.gov), the median down payment for first-time homebuyers is just 6-7% of the purchase price. Conventional loans allow as little as 3% down for qualified borrowers. FHA loans backed by the Federal Housing Administration require only 3.5% down with a credit score of 580 or higher. VA loans for eligible veterans and active-duty service members require zero down payment. USDA loans for rural property purchases also offer 0% down options for income-eligible buyers.
The tradeoff for a smaller down payment is higher monthly costs through private mortgage insurance (PMI), a larger loan balance, and more total interest paid over the life of the loan. This calculator helps you visualize exactly how each scenario compares so you can choose the right balance between upfront savings and long-term cost.
How PMI Affects Your Monthly Payment
Private mortgage insurance (PMI) is required on conventional loans when the down payment is less than 20% of the home price. PMI protects the lender — not the borrower — against default risk. According to the CFPB, PMI typically costs between 0.5% and 1% of the total loan amount per year, added to your monthly mortgage payment. On a $380,000 loan (5% down on a $400,000 home), PMI adds roughly $158 to $317 per month.
The good news: PMI is not permanent. Under the Homeowners Protection Act, your lender must automatically cancel PMI once your loan balance reaches 78% of the original home value. You can also request cancellation at 80% loan-to-value (LTV). FHA loans use a different system called mortgage insurance premium (MIP), which requires both an upfront premium (1.75% of the loan) and annual premiums (0.55% for most loans) that last the entire loan term unless you put at least 10% down. Use the comparison table above to see exactly how much PMI adds to each scenario.
Down Payment by Loan Type
Each mortgage program has different down payment requirements, eligibility criteria, and insurance structures. Here is a comparison based on 2026 guidelines from Fannie Mae, FHA, VA, and USDA:
- Conventional: Minimum 3-5% down. PMI required below 20%. Best rates for credit scores above 740. No upfront mortgage insurance fee.
- FHA: Minimum 3.5% down (580+ credit) or 10% down (500-579 credit). Requires both upfront MIP (1.75%) and annual MIP (0.55%). MIP lasts the life of the loan for less than 10% down.
- VA: Zero down payment required. No PMI. Requires VA funding fee (1.25-3.3% of loan) unless exempt. Available only to veterans, active-duty military, and eligible surviving spouses.
- USDA: Zero down payment. Requires upfront guarantee fee (1%) and annual fee (0.35%). Property must be in a USDA-eligible rural area. Income limits apply based on county median.
VA and USDA loans offer the lowest barrier to entry but have strict eligibility requirements. For most buyers, the choice comes down to conventional versus FHA — and the right answer depends on your credit score, savings, and how long you plan to stay in the home.
Strategies to Save for a Down Payment
Building a down payment fund is the biggest financial hurdle for most homebuyers. According to HUD (hud.gov), several programs and strategies can accelerate your timeline:
- First-time buyer programs: Many states offer down payment assistance (DPA) grants or low-interest second mortgages. Check your state housing finance agency for current programs — some provide $10,000-$25,000 in assistance.
- Gift funds: Conventional loans allow 100% of the down payment to come from family gift funds for purchases with 20%+ down. FHA allows gift funds for the full 3.5% minimum. Document the gift with a signed letter.
- Employer programs: Some employers offer homebuyer assistance or housing stipends. Government employees may qualify for the Good Neighbor Next Door program (50% discount in revitalization areas).
- Automated savings: Set up automatic transfers on payday to a dedicated high-yield savings account. Even $500/month reaches $18,000 in three years — enough for 3.5% on a $500,000 home.
- IRA withdrawal: First-time buyers can withdraw up to $10,000 from a traditional IRA penalty-free for a home purchase. Roth IRA contributions (not earnings) can be withdrawn anytime without penalty.
