Mortgage Calculator 0 Deposit

This mortgage calculator helps you determine your monthly payments and total interest for a mortgage with a 0% deposit. A 0% deposit mortgage means you don't need to pay any money upfront to secure the loan, which can be helpful if you don't have savings for a down payment.

How a 0% Deposit Mortgage Works

A 0% deposit mortgage is a type of mortgage loan where the borrower doesn't need to pay any money upfront. Instead, the lender covers the entire purchase price of the property, and the borrower repays the loan over time with interest.

Key Features

No upfront payment required
Lender covers the full purchase price
Repayment includes principal and interest
Typically higher interest rates than conventional mortgages
May have different eligibility requirements

The lender will typically require you to have a good credit score and stable income to qualify for a 0% deposit mortgage. The interest rate on these loans is usually higher than on conventional mortgages, which means you'll pay more in interest over the life of the loan.

Mortgage Payment Formula

The monthly payment for a mortgage is calculated using the formula:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1 ]

Where:

M = monthly payment
P = principal loan amount
i = monthly interest rate (annual rate divided by 12)
n = number of payments (loan term in years multiplied by 12)

How to Qualify for a 0% Deposit Mortgage

Qualifying for a 0% deposit mortgage typically requires meeting certain criteria set by the lender. Common requirements include:

Good credit score: Most lenders require a credit score of at least 620, though some may require higher scores.
Stable income: You'll need to demonstrate a consistent income and employment history.
Debt-to-income ratio: Lenders typically prefer a debt-to-income ratio of 43% or lower.
Proof of assets: You may need to provide documentation of your assets, such as savings or investments.
Property valuation: The property you want to purchase must be valued appropriately by the lender.

Some lenders may offer 0% deposit mortgages to first-time buyers or those in specific professions, such as teachers or nurses. It's important to research different lenders to find the best terms for your situation.

Worked Examples

Let's look at two examples to illustrate how a 0% deposit mortgage works.

Example 1: 30-Year Fixed Rate Mortgage

Suppose you want to purchase a property for $300,000 with a 0% deposit mortgage. The lender offers a 30-year fixed rate mortgage at 4.5% annual interest.

Calculation

Using the mortgage payment formula:

P = $300,000

i = 4.5% / 12 = 0.00375 per month

n = 30 years × 12 = 360 months

M = $300,000 [ 0.00375(1 + 0.00375)³⁶⁰ ] / [ (1 + 0.00375)³⁶⁰ - 1 ]

M ≈ $1,616.00 per month

Over the 30-year term, you would pay approximately $471,360 in total, with $171,360 going toward interest.

Example 2: 15-Year Fixed Rate Mortgage

For the same property, let's consider a 15-year fixed rate mortgage at 3.5% annual interest.

Calculation

Using the mortgage payment formula:

P = $300,000

i = 3.5% / 12 ≈ 0.00292 per month

n = 15 years × 12 = 180 months

M = $300,000 [ 0.00292(1 + 0.00292)¹⁸⁰ ] / [ (1 + 0.00292)¹⁸⁰ - 1 ]

M ≈ $2,130.00 per month

Over the 15-year term, you would pay approximately $383,400 in total, with $83,400 going toward interest.
