Security Deposit Interest Calculator Ontario

Reviewed by Calculator Editorial Team

In Ontario, security deposits are common in rental agreements. Understanding how interest is calculated on these deposits can help tenants and landlords manage expectations. This calculator helps you determine the interest earned on a security deposit over time.

How Security Deposit Interest Works in Ontario

Security deposits in Ontario are typically held by landlords or property management companies. The interest on these deposits is usually calculated using the Ontario rate of return, which is the minimum rate required by law for landlords to hold security deposits.

The Ontario rate of return is currently set at 4% per annum. This means that if a tenant pays a security deposit, the landlord must invest the money in a way that earns at least 4% interest annually. The interest earned is then credited back to the tenant's account when the deposit is returned.

Note: The Ontario rate of return is subject to change. Always check the current rate before calculating interest on a security deposit.

How to Calculate Security Deposit Interest

Calculating security deposit interest involves determining the amount of interest earned on the deposit over a specific period. The calculation is straightforward but requires knowing the deposit amount, the interest rate, and the time period.

To calculate the interest, you can use the simple interest formula:

Interest = Principal × Rate × Time

Where:

  • Principal is the security deposit amount
  • Rate is the interest rate (4% in Ontario)
  • Time is the number of years the deposit is held

The Formula

The formula for calculating security deposit interest is:

Interest = (Deposit Amount × Interest Rate × Time) / 100

This formula calculates the simple interest earned on the security deposit. The result is the amount of interest that would be credited back to the tenant's account.

Worked Example

Let's say a tenant pays a security deposit of $1,000 in Ontario. The interest rate is 4% per annum, and the deposit is held for 2 years.

Using the formula:

Interest = ($1,000 × 4% × 2) / 100 = $80

This means the tenant would earn $80 in interest on their $1,000 security deposit over 2 years.
