Down Payment Calculator – Estimate Costs

A Down Payment Calculator can help you work out how much you should pay as a deposit when purchasing assets such as a home or car. It can show you how much you may need to borrow. Having a good understanding of how much deposit you’ll need to pay is a key part of any financial planning when buying a home in the USA.

When buying a house, your deposit will be the amount of money paid as part of the purchase price. For example, if you wanted to buy a home and pay a deposit of $350,000 and make a 20% down payment, you will pay $70,000 and then borrow the remaining $280,000.

The larger the deposit you pay, the less you’ll need to borrow. This can lead to lower monthly payments on your mortgage and less interest paid overall. It can also help you avoid paying for Private Mortgage Insurance (PMI) on certain types of conventional loans.

However, you may not need to pay a 20% deposit when buying a home. Depending on what type of loan you are applying for, your credit status and your eligibility, you could be eligible for a mortgage with a deposit as low as 3% or 3.5%.

Our Down Payment Calculator allows you to easily see how much you’ll need to pay as a deposit when purchasing. Here’s how to use it:

Down Payment Calculator Formula

Deposits are calculated using the following formula:

Down Payment

Purchase Price x Deposit Percentage / 100

Loan Amount

Purchase Price – Deposit Amount

Deposit Percentage

Deposit Amount / Purchase Price x 100

Example

Let’s say you were looking to buy a home in Texas for $350,000. You wanted to pay 10% as a deposit.

1. Deposit

$350,000 x 10 / 100 = $35,000.

2. Loan Amount

$35,000 = $350,000 − $315,000.

You would need to borrow $35,000 for the down payment and would need to finance the remaining $315,000 via a mortgage (excluding any closing costs or other additional costs).

You can also see how much you’d need to pay as a deposit for different deposit percentages:

By comparing the deposit amounts you can see how the more you pay as a deposit, the less you’ll need to borrow.

Understanding the Results

Once you’ve entered your details you’ll see a number of key pieces of information.

Deposit Amount: Total amount of money you’ll need to pay as a deposit.

• Deposit Percentage: Percentage of your purchase price that you’ll be paying as a deposit.
• Loan Amount: Total amount you’ll need to borrow once your deposit has been deducted from the purchase price. Generally, this will be the initial amount of principal you’ll need to pay on a mortgage for buying a home.
• Purchase Price: Total amount you’ll be paying for the property/asset.
• Equity: This shows how much equity you are putting into the property. When buying a home this could be affected by how much the property is worth in the market and other factors.

The loan amount isn’t your monthly mortgage payment. It will also depend on the interest rate, length of loan, property taxes, homeowners insurance and other factors.

Factors Influencing Your Deposit

There are a number of factors that could impact how much deposit you’ll need to pay when buying a home in the USA.

Purchase Price

The purchase price will directly impact how much you’ll need to pay as a deposit. The higher the price of the home, the more you’ll need to pay.

Type of Mortgage

Depending on the type of mortgage you’re applying for, different deposit requirements will apply. Conventional loans may offer lower deposits from 3%. FHA loans will usually require a minimum of 3.5% deposit if you meet the relevant credit criteria. VA and USDA loans may offer zero deposits for eligible borrowers.

Credit Score

Your credit score can impact what mortgage you’re eligible for, the interest rates and what loans are available. Some lenders may also have different requirements depending on your credit.

Lenders

Your income, debts, credit history, savings and other factors will be considered by your mortgage lender. This can impact the minimum deposit you’ll need.

Private Mortgage Insurance

Many conventional mortgages will require you to pay Private Mortgage Insurance if you don’t pay a 20% deposit. This is an insurance that protects the lender and not you. By paying more as a deposit you may be able to avoid this extra cost.

Savings

Your personal savings will impact how much you can afford to pay as a deposit. It’s important to have an emergency fund.

Debt to Income Ratio

Your debt to income (DTI) ratio compares your monthly debts to your gross monthly income. Lenders will use this to see how well you can manage your mortgage payments and other financial commitments.

Help With Financial Decisions

Accuracy & Assumptions

The Down Payment Calculator will give you an estimate based on the price of the property and deposit amount/percentage. The maths used follows standard formula. It assumes that the deposit will be applied directly to the purchase price.

However, there are some limitations:

It will not tell you if you’ll be approved for your mortgage.

It won’t automatically add in any closing costs, property taxes, homeowners insurance or lender fees.

It will not calculate PMI, interest or monthly payments unless added.

The actual deposit will depend on the mortgage you’re applying for, lender criteria, property type and your eligibility.

Some loan types may have further requirements and restrictions depending on where you live.

The loan amount shown may not match the actual mortgage amount if there are additional costs to be borrowed.

Please note that the results are just an estimate and shouldn’t be considered professional financial or mortgage advice.

To get a more accurate idea of how much you’ll need to spend when buying a home, think about how much you’ll need to pay as a deposit, plus closing costs, moving costs, emergency savings and ongoing costs of being a homeowner. Speak to a qualified mortgage lender to confirm how much you’ll need to borrow.

FAQs

What is a deposit when buying a house?

A deposit is the amount of money you pay when purchasing a home. It’s a percentage of the total price of the property and the rest is usually borrowed via a mortgage. For example, if you pay 10% deposit on a $300,000 home equals $30,000.

How much deposit do I need to buy a house in the USA?

The deposit will depend on what mortgage you’re applying for. Some conventional loans offer low deposits starting from 3%. FHA loans will usually require 3.5% deposit for eligible borrowers. Qualified VA and USDA borrowers may be able to buy a home with zero deposit.

Do I need to pay 20% deposit?

Not necessarily. Many people will be eligible for mortgages with a lower deposit. However, paying 20% deposit will usually help you avoid paying for Private Mortgage Insurance (PMI) on a conventional mortgage.

How do I calculate a 10% deposit on a $400,000 home?

Multiply the purchase price by 10%. For example, $400,000 × 0.10 = $40,000. Your estimated loan amount would be $360,000 (excluding any extra costs).

Will I pay less per month by paying a larger deposit?

Yes. The more you pay as a deposit, the less you’ll need to borrow. This means your monthly payments will generally be lower. It can also help you avoid paying for PMI on eligible conventional mortgages.

What else should I consider?

You should also budget for closing costs, home inspection and valuation fees, property taxes, homeowners insurance, moving costs and possible maintenance costs. Closing costs in the USA are generally between 2% and 5% of the purchase price. However, this will vary depending on where you live, lender and transaction.

Can I use a Down Payment Calculator when buying a car?
