About Down Payment Calculator
Welcome to the Down Payment Calculator, a comprehensive mortgage planning tool that shows you exactly how your down payment affects monthly costs, PMI requirements, and total interest over the life of your loan. Whether you are a first-time homebuyer deciding between 5% and 20% down, or comparing different home price scenarios, this calculator provides a clear financial picture to help you make the best decision.
What Is a Down Payment?
A down payment is the upfront cash you pay when purchasing a home. It is expressed as a percentage of the home's purchase price. For example, a 20% down payment on a $350,000 home is $70,000. The remaining 80% ($280,000) becomes your mortgage loan.
Common Down Payment Levels
| Down Payment % | Typical Loan Type | PMI Required? | Best For |
|---|---|---|---|
| 0% | VA, USDA | No (but may have funding fee) | Eligible veterans, rural buyers |
| 3 – 3.5% | Conventional, FHA | Yes | First-time buyers with limited savings |
| 5 – 10% | Conventional | Yes | Buyers who want to keep cash reserves |
| 20%+ | Conventional | No | Buyers who want lowest monthly payment |
What Is PMI (Private Mortgage Insurance)?
Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20%. It protects the lender — not you — if you default on the loan. PMI typically costs 0.3% to 1.5% of the original loan amount per year and is added to your monthly payment.
- When it starts: From day one if your down payment is under 20%
- When it ends: You can request removal at 20% equity; it auto-terminates at 22% equity
- How to avoid it: Make a 20%+ down payment, use a VA or USDA loan, or consider lender-paid PMI (higher rate)

Tips for Saving for a Down Payment
- Set a target date: Divide your target amount by the months until your goal date for a monthly savings target
- Automate savings: Set up automatic transfers to a dedicated house fund
- Explore assistance programs: Many states offer down payment assistance for first-time buyers
- Consider gift funds: Most loan programs allow family gift money for part or all of the down payment
- Balance down payment vs. reserves: Do not deplete all savings — keep 3-6 months of expenses as an emergency fund
Frequently Asked Questions
How much should I put down on a house?
The ideal down payment depends on your financial situation. Putting 20% down eliminates Private Mortgage Insurance (PMI) and lowers monthly payments. However, many buyers start with 3-10% down. FHA loans allow as little as 3.5% down, while VA and USDA loans may require 0% down for eligible borrowers.
What is PMI and when is it required?
Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20% of the home price. PMI protects the lender if you default. It typically costs 0.3% to 1.5% of the loan amount annually and can be removed once you reach 20% equity.
Does a larger down payment mean lower monthly payments?
Yes, a larger down payment reduces your loan amount, which directly lowers your monthly principal and interest payments. Additionally, reaching 20% or more eliminates PMI, further reducing monthly costs. A larger down payment also means you pay less total interest over the life of the loan.
What are the benefits of a 20% down payment?
A 20% down payment eliminates PMI (saving hundreds per month), results in lower monthly payments, gives you instant equity in your home, may qualify you for better interest rates, and reduces the total interest paid over the loan term. It is the benchmark that most financial advisors recommend.
Can I buy a house with less than 20% down?
Absolutely. Many loan programs accept lower down payments: conventional loans as low as 3%, FHA loans at 3.5%, and VA or USDA loans at 0% for eligible borrowers. The trade-off is higher monthly payments due to PMI and a larger loan amount, but it allows you to enter the housing market sooner.
