A larger down payment lowers your monthly mortgage payment and the total interest you pay over the life of the loan
When you put more money down at closing, you borrow less from the lender. A smaller loan balance means a smaller monthly payment. If you put down 20 percent instead of 5 percent on a $300,000 home, you borrow $240,000 instead of $285,000—a difference of $45,000. On a 30-year mortgage at 7 percent interest, that $45,000 difference cuts your monthly payment by roughly $300.
The interest savings compound over time. On that same loan, borrowing $240,000 instead of $285,000 means you pay tens of thousands of dollars less in interest across 30 years. The exact amount depends on your interest rate and loan term, but the direction is always the same: more down means less total interest.
A larger down payment also removes the requirement for mortgage insurance. When you borrow more than 80 percent of the home's value, lenders require you to pay private mortgage insurance (PMI) or, for government loans, an insurance premium built into your rate. This insurance protects the lender if you default, but it costs you. PMI typically runs 0.5 to 1.5 percent of your loan amount per year. Putting down 20 percent or more eliminates this cost entirely.
Key Takeaways
- A larger down payment reduces the amount you borrow, which lowers your monthly mortgage payment and the total interest paid over the loan term.
- Putting down 20 percent or more eliminates the requirement for mortgage insurance, which can save you hundreds of dollars per year.
- The interest rate you receive may improve with a larger down payment, because lenders view larger down payments as lower risk.
- A larger down payment reduces your loan-to-value ratio, which affects how much you can borrow and the terms lenders offer you.
- The trade-off is that money in a down payment is not available for other uses, such as emergency savings or investments.
How down payment size affects your interest rate
Lenders sometimes offer better interest rates to borrowers who put down more money. The relationship is not automatic—your credit score, income, and the current market matter more—but a larger down payment signals lower risk to the lender. You are borrowing less relative to the home's value, so the lender has more cushion if the home loses value or you stop paying.
The rate improvement is usually small, often a quarter to half a percentage point. On a $240,000 loan, a 0.25 percent rate difference means roughly $40 per month in savings. It is worth asking your lender whether a larger down payment qualifies you for a better rate, but do not assume it will happen. Shop with multiple lenders to see what rates they actually offer at different down payment levels.
The loan-to-value ratio and what lenders will offer
Your loan-to-value ratio (LTV) is the loan amount divided by the home's purchase price. A $240,000 loan on a $300,000 home is an 80 percent LTV. A $285,000 loan on the same home is a 95 percent LTV. Lenders use this number to decide whether to lend to you at all, how much they will lend, and what rate they will charge.
Most conventional lenders prefer an LTV of 80 percent or lower. At that threshold, you avoid mortgage insurance and often get the best rates available. Between 80 and 95 percent LTV, you pay mortgage insurance and may face slightly higher rates. Above 95 percent LTV, some lenders will not work with you, or they charge significantly more. A larger down payment improves your LTV, which opens up better loan options.
When a larger down payment does not help as much
If you already have a strong credit score (740 or higher) and stable income, the rate improvement from a larger down payment may be minimal. Lenders price risk based on multiple factors, and your creditworthiness matters as much as your down payment. A borrower with a 760 credit score and 10 percent down may get nearly the same rate as one with a 760 score and 25 percent down.
If you are buying in a declining market or in an area where homes are harder to sell, a larger down payment helps less because the lender's risk is tied to the property itself, not just your finances. In these cases, the main benefit of a larger down payment is the lower monthly payment and eliminated mortgage insurance.
The cost of tying up money in a down payment
A larger down payment means less cash in your pocket after closing. Money in a down payment cannot be used for emergency repairs, medical bills, job loss, or other unexpected costs. If you drain your savings to put 25 percent down and then face a $5,000 repair six months later, you may end up borrowing at a higher rate or paying credit card interest.
Consider your full financial picture. If you have three to six months of expenses in emergency savings after the down payment, a larger down payment makes sense. If putting down more than 10 or 15 percent would leave you with less than one month of expenses saved, keep more cash on hand. The monthly payment savings from a larger down payment are real, but they do not outweigh the risk of having no financial cushion.
Down payment size and different loan types
Conventional loans (not backed by the government) typically reward larger down payments most clearly. At 20 percent down, you avoid mortgage insurance and often get the best rates. At 10 percent down, you pay mortgage insurance. At 5 percent or less, mortgage insurance costs more and some lenders charge higher rates.
FHA loans (backed by the Federal Housing Administration) require mortgage insurance at any down payment level, even at 20 percent. The insurance premium is built into your rate and monthly payment. A larger down payment still lowers your monthly payment because you borrow less, but it does not eliminate the insurance cost. VA loans (for military members) and USDA loans (for rural properties) have their own insurance structures that do not always improve with larger down payments in the same way.
Comparing the numbers: what a larger down payment actually saves
Here is a concrete example. You are buying a $300,000 home with a 30-year mortgage at 7 percent interest.
| Down Payment | Loan Amount | Monthly Payment (Principal + Interest) | Mortgage Insurance (if applicable) | Total Monthly Cost | Total Interest Paid Over 30 Years |
|---|---|---|---|---|---|
| 5% ($15,000) | $285,000 | $1,897 | $356 (0.75% PMI) | $2,253 | $398,920 |
| 10% ($30,000) | $270,000 | $1,797 | $202 (0.5% PMI) | $1,999 | $377,640 |
| 20% ($60,000) | $240,000 | $1,597 | $0 | $1,597 | $335,040 |
| 30% ($90,000) | $210,000 | $1,398 | $0 | $1,398 | $293,280 |
The jump from 5 to 20 percent down saves $656 per month and $63,880 in total interest. The jump from 20 to 30 percent saves another $199 per month and $41,760 in interest. The savings are real, but they diminish as you go higher. The biggest benefit usually comes from reaching 20 percent, where mortgage insurance disappears.
Frequently Asked Questions
Can I get a mortgage with less than 5 percent down?
Yes. Some conventional lenders offer 3 percent down programs. FHA loans allow down payments as low as 3.5 percent. The trade-off is higher mortgage insurance costs and sometimes a higher interest rate. You will pay more over the life of the loan, but you need less cash upfront.
If I put down 20 percent, will my interest rate automatically be better?
Not automatically. Your credit score, income, debt levels, and the current market all affect your rate. A 20 percent down payment removes mortgage insurance and may help you may have access to for better terms, but shop with multiple lenders to see what rates they actually offer you.
What if I put down more than 30 percent?
Your monthly payment continues to drop because you borrow less. The interest savings also continue. However, the benefit per additional dollar decreases. Putting down 40 percent instead of 30 percent saves less per month than putting down 30 instead of 20. At some point, the money might be better used elsewhere.
Can I remove mortgage insurance later if I put down less now?
Yes, once your loan balance falls to 80 percent of the home's original value (through payments or home appreciation), you can request to remove PMI on a conventional loan. This usually takes several years. FHA mortgage insurance is harder to remove and may stay for the life of the loan depending on your down payment.
Does a larger down payment help if I have bad credit?
It helps somewhat. A larger down payment shows commitment and lowers the lender's risk, which may help you get approved when you otherwise would not. However, if your credit score is very low, some lenders will decline you regardless of down payment size. Work on improving your credit score while saving for a larger down payment.
