5 Deposit Mortgage Calculator

Buying a home is one of the biggest financial decisions most people will ever make. Before applying for a mortgage, it is essential to understand how much deposit you need, the size of your loan, your monthly repayments, and the total cost of borrowing over time.

5% Deposit Mortgage Calculator

A 5% Deposit Mortgage Calculator helps potential homebuyers quickly estimate these important figures. By entering the property price, mortgage term, and interest rate, you can instantly calculate the required deposit, mortgage amount, monthly payment, total repayment, and total interest paid throughout the life of the loan.

Whether you're a first-time buyer, upgrading to a larger property, or simply exploring your options, this calculator provides valuable insights that can help you make informed financial decisions.


What Is a 5% Deposit Mortgage?

A 5% deposit mortgage is a home loan where the buyer contributes 5% of the property's purchase price as a down payment. The lender finances the remaining 95%.

This type of mortgage is popular among first-time buyers because it requires a smaller upfront investment compared to traditional mortgages that may require 10%, 15%, or 20% deposits.

Example

Suppose a property costs $300,000.

DescriptionAmount
Property Price$300,000
5% Deposit$15,000
Mortgage Amount$285,000

In this scenario, the buyer needs to provide $15,000 as a deposit, while the lender finances $285,000.

Understanding the Calculator Results

The calculator provides five key outputs.

1. 5% Deposit Required

This is the amount you must contribute toward the property purchase.

Formula

Deposit=Property Price×0.05Deposit = Property\ Price \times 0.05Deposit=Property Price×0.05

Example

Property Price = $400,000

Deposit = $400,000 × 0.05

Deposit = $20,000


2. Mortgage Amount

The mortgage amount represents the money borrowed from the lender after subtracting the deposit.

Formula

Mortgage Amount = Property Price − Deposit

Example

ItemAmount
Property Price$400,000
Deposit$20,000
Mortgage Amount$380,000

3. Monthly Mortgage Payment

This is the estimated amount paid every month toward the mortgage.

Monthly payments include:

  • Principal repayment
  • Interest charges

The calculator uses the standard mortgage amortization formula to estimate monthly payments accurately.

Factors Affecting Monthly Payments

  • Property price
  • Deposit amount
  • Interest rate
  • Mortgage term

Generally:

  • Higher interest rates increase payments.
  • Longer terms reduce monthly payments.
  • Larger deposits reduce borrowing costs.

4. Total Repayment

Total repayment is the full amount paid to the lender during the mortgage term.

Formula

Total Repayment = Monthly Payment × Number of Monthly Payments

This includes both principal and interest.


5. Total Interest Paid

Total interest shows the cost of borrowing money.

Formula

Total Interest = Total Repayment − Mortgage Amount

This figure helps borrowers understand the true long-term cost of the mortgage.
