How Much Should You Put Down Without Draining Your Savings

November 06, 2026•6 min read

The right down payment gives you a monthly payment you can manage and enough money left for life after closing. That may be less than 20%, exactly 20%, or more.

I want you to look at both sides of the decision: what you will pay each month and what you will still have in savings. A lower payment helps. So does being able to handle a repair without reaching for a credit card.

What does putting more down buy you

Let's compare two conventional loans for a $750,000 detached, single-family primary residence. Both examples use a 30-year fixed loan at a 7.5% interest rate, with 360 monthly principal-and-interest payments. The APR is 7.912% with 10% down and 7.551% with 20% down. This is a historical illustration, not today's rate offer.

These are not total housing payments. Property taxes and homeowners insurance vary by location and property and are excluded from these examples, so the actual payment obligation will be greater. Flood insurance, HOA dues and other assessments are also excluded when applicable.

The 10% option uses the monthly PMI supplied for this scenario. The 20% option assumes the appraisal supports the purchase price, making the loan 80% of the property's value with no PMI. Fannie Mae mortgage-insurance requirements

Putting another $75,000 down lowers the initial monthly principal, interest and PMI by $811.29. That includes $524.41 less in principal and interest, plus $286.88 less in PMI.

Would that monthly reduction make a meaningful difference to your budget? Or would keeping the $75,000 available give you more room for emergencies, repairs or uneven income?

The $811.29 is an initial cash-flow difference, not a lifetime savings figure or investment return. Part of each payment repays principal, and the difference narrows if the 10% option's PMI ends.

Closing costs and prepaid items are additional. Use the property's actual Loan Estimate, including any lender or seller credits, to compare cash to close. Keeping $75,000 out of the down payment does not mean you will have that entire amount left after closing. CFPB Loan Estimate guide

Decide what needs to stay in savings

Before increasing your down payment, set aside money for:

  • An emergency cushion based on your expenses and income stability.

  • Moving, utility setup and other unpaid costs.

  • Repairs or improvements you expect soon.

  • Other commitments you cannot comfortably postpone.

The CFPB suggests three to six months of expenses as an emergency-cushion guideline. Use your expected expenses after moving and adjust for your household. CFPB down-payment planning

Ask about lender reserve requirements, too. Those depend on the transaction and may overlap with your emergency savings; they are not automatically a second pot of money you must add on top. Fannie Mae reserve requirements

Is avoiding PMI worth putting 20 percent down

Sometimes. Conventional loans with less than 20% down typically require private mortgage insurance. Its actual cost belongs in the comparison, but avoiding it should not leave you without a comfortable cash cushion. CFPB mortgage-insurance guide

Borrower-paid PMI also does not necessarily last for the life of the loan. On many eligible conventional mortgages, you can request cancellation when the loan balance reaches 80% of the home's original value, subject to conditions including payment history, current payments, property value and other liens. Automatic termination generally occurs at the scheduled 78% point if payments are current. Appreciation alone does not automatically remove it. CFPB PMI cancellation rules

How do FHA and VA change the decision

FHA: Include both upfront and ongoing mortgage insurance premiums, or MIP. A lower interest rate alone does not tell you which loan costs less. For FHA case numbers assigned on or after June 3, 2013, ongoing MIP generally lasts 11 years when the original loan-to-value ratio is 90% or less, or the loan term when it is above 90%, unless the loan is paid off earlier. Conventional PMI cancellation rules do not apply. HUD MIP duration guidance

VA: Eligible borrowers may be able to buy with no down payment, subject to entitlement, lender requirements and the property's appraised value. VA loans do not have mortgage insurance. VA purchase-loan guidance

A one-time VA funding fee may apply unless you qualify for an exemption. For purchase loans subject to the fee, down payments of at least 5% or 10% can reduce the funding-fee rate. Verify your exemption status before comparing costs. No down payment does not mean no closing costs. VA funding-fee guidance

What if I want to put more than 20 percent down

A larger down payment can make sense if you prefer a smaller loan and still retain the cash you need. There is no reason to stop at 20% if a larger amount fits your goals, and no reason to empty your savings just because you can.

Choose the amount that lets you say: "The payment fits my budget, and I have enough left after closing, moving and planned repairs." If either side feels uncomfortable, revisit the down payment or purchase price.

Illustration assumptions: Calculated October 31, 2026 from the scenario supplied October 28, 2026, with the 30-year fixed term confirmed October 31. APRs were supplied November 6, 2026. The scenario used a 680 FICO score; credit affects pricing and PMI, so these figures should not be assumed for a different credit profile. The example assumes a one-unit primary residence, appraisal at least equal to the $750,000 price, fully amortizing conventional loans and no financed costs. Principal and interest are rounded to cents. PMI is an initial amount, not a promise that it continues unchanged for 360 months. The 7.5% interest rate is used to calculate principal and interest. The annual percentage rates (APRs) are 7.912% for 10% down and 7.551% for 20% down. APR reflects the interest rate and certain loan costs; it is not the rate used to calculate the monthly principal-and-interest payment. Points, closing costs and prepaid expenses are not included in the illustrated loan balances or payments. Actual terms depend on the borrower, property, location and available program. This historical illustration is not a current rate offer or commitment to lend. All loans are subject to underwriting and approval.
