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.
| Description | Amount |
|---|---|
| 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×0.05
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
| Item | Amount |
|---|---|
| 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.
Mortgage Calculation Example
Let's walk through a practical example.
Mortgage Details
| Input | Value |
|---|---|
| Property Price | $300,000 |
| Deposit Percentage | 5% |
| Mortgage Term | 30 Years |
| Interest Rate | 6% |
Step 1: Calculate Deposit
$300,000 × 5% = $15,000
Step 2: Calculate Mortgage Amount
$300,000 − $15,000 = $285,000
Estimated Results
| Result | Amount |
|---|---|
| Deposit | $15,000 |
| Mortgage Amount | $285,000 |
| Monthly Payment | $1,709 |
| Total Repayment | $615,240 |
| Total Interest | $330,240 |
Values are approximate and may vary slightly based on lender calculations.
How Interest Rates Affect Mortgage Costs
Interest rates have a major impact on affordability.
Consider a $285,000 mortgage over 30 years.
| Interest Rate | Approx. Monthly Payment |
|---|---|
| 4% | $1,360 |
| 5% | $1,530 |
| 6% | $1,709 |
| 7% | $1,896 |
As rates increase, monthly payments and total interest costs rise significantly.
This is why comparing lenders and securing a competitive interest rate is important.
How Mortgage Term Affects Payments
The mortgage term also influences affordability.
Assume:
- Loan Amount: $285,000
- Interest Rate: 6%
| Mortgage Term | Approx. Monthly Payment |
|---|---|
| 15 Years | $2,405 |
| 20 Years | $2,042 |
| 25 Years | $1,835 |
| 30 Years | $1,709 |
