Interest on Last Month's Rent Ontario 2018 Calculator

This calculator helps you determine the interest charged on last month's rent in Ontario for 2018. Understanding how late rent payments are calculated can help you budget and avoid financial surprises.

How the Calculator Works

When you don't pay your rent on time, landlords in Ontario may charge interest on the unpaid amount. The Ontario Landlord and Tenant Board sets the maximum interest rate that can be charged, which was 10% per year in 2018.

Note: The interest rate may vary depending on the specific rental agreement and local regulations. This calculator uses the 2018 Ontario rate of 10% per year.

The calculator works by:

Calculating the daily interest rate by dividing the annual rate by 365
Determining the number of days between the due date and the payment date
Multiplying the unpaid rent by the daily interest rate and the number of days
Displaying the total interest charged

Formula Used

Interest = (Unpaid Rent × Daily Interest Rate × Number of Days)

Where Daily Interest Rate = Annual Interest Rate / 365

The formula accounts for the time value of money, ensuring you're calculating the exact interest that would have been charged if the rent was paid late.

Worked Example

Let's say you owe $1,200 in rent and didn't pay it until 15 days after the due date in 2018.

Example Calculation

1. Annual interest rate: 10%

2. Daily interest rate: 10% ÷ 365 ≈ 0.0274%

3. Number of days late: 15

4. Interest: $1,200 × 0.000274 × 15 ≈ $5.19

Total interest charged: $5.19

This example shows how quickly small amounts of interest can add up when rent payments are delayed.
