Mortgage Deposit Calculator
Estimate how much deposit you need for a home purchase and what percentage of the property price it represents.
Overview
A mortgage deposit calculator helps you estimate how much cash you may need upfront when buying a property. Enter the property price, your planned deposit percentage, and any extra upfront costs to see your estimated deposit, loan amount, and loan-to-value ratio.
How it works
The calculator multiplies the property price by your chosen deposit percentage to estimate the deposit amount. It then subtracts that deposit from the property price to estimate the mortgage loan amount. The loan-to-value ratio is calculated by dividing the loan amount by the property price, and total upfront cash needed adds your deposit to any extra upfront costs you enter.

Example Calculation
Property price
$350,000
Deposit percentage
20%
Extra upfront costs
$5,000
Estimated deposit
$70,000
For a $350,000 property with a 20% deposit, the estimated deposit is $70,000, the loan amount is $280,000, the loan-to-value ratio is 80.0%, and total upfront cash needed is $75,000.
Frequently asked questions
What does a mortgage deposit calculator estimate?
It estimates the cash deposit needed for a property purchase, the likely loan amount, the loan-to-value ratio, and your total upfront cash requirement.
How much deposit do I usually need for a mortgage?
Many buyers aim for a deposit of 5% to 20% of the property price, but the amount required depends on the lender, loan type, and your circumstances.
What is loan-to-value ratio?
Loan-to-value ratio, or LTV, is the loan amount divided by the property price, shown as a percentage. A lower LTV usually means a larger deposit.
Should I include fees and closing costs?
Yes, if you want a more realistic estimate of the cash you need upfront. These costs can add significantly to your total budget.
Does a bigger deposit reduce the mortgage amount?
Yes. A larger deposit reduces the amount you need to borrow, which may also improve your LTV ratio.
