Calculating Pre and Post Judgment Interest Ontario

In Ontario, judgment interest is a crucial aspect of civil litigation that affects both plaintiffs and defendants. Understanding how to calculate pre and post judgment interest is essential for legal professionals and individuals involved in court proceedings. This guide provides a comprehensive overview of judgment interest in Ontario, including the calculation methods and practical considerations.

What is Judgment Interest?

Judgment interest refers to the interest that accrues on a judgment debt from the date of the judgment until the debt is paid in full. In Ontario, judgment interest is calculated differently before and after a judgment is entered. Understanding these differences is crucial for both litigants and legal professionals.

Key Points

Judgment interest is calculated differently before and after a judgment is entered
Pre-judgment interest is calculated from the date of the last payment to the date of judgment
Post-judgment interest is calculated from the date of judgment until the debt is paid
Ontario follows the common law approach to judgment interest

The calculation of judgment interest is governed by the Interest Act and common law principles. In Ontario, judgment interest is typically calculated at the same rate as the general interest rate applicable to commercial loans, which is currently 5% per annum. However, the exact rate can vary depending on the circumstances of the case.

Pre-Judgment Interest

Pre-judgment interest is the interest that accrues on a debt from the date of the last payment to the date of judgment. This type of interest is calculated based on the time period between the last payment and the judgment date.

Pre-Judgment Interest Formula

Pre-Judgment Interest = (Principal Amount × Daily Interest Rate × Number of Days) / 365

Where:

Principal Amount = The amount of the debt at the time of the last payment
Daily Interest Rate = Annual interest rate divided by 365
Number of Days = Days between the last payment and judgment date

For example, if a judgment is entered on January 15, 2023, and the last payment was made on October 1, 2022, with a principal amount of $10,000 and an annual interest rate of 5%, the pre-judgment interest would be calculated as follows:

Example Calculation

Number of days = (January 15, 2023 - October 1, 2022) = 96 days

Daily interest rate = 5% ÷ 365 ≈ 0.0137%

Pre-judgment interest = ($10,000 × 0.0137% × 96) ÷ 365 ≈ $37.65

Pre-judgment interest is typically awarded to the prevailing party to compensate for the time value of money lost during the litigation process. It is important to note that pre-judgment interest is not awarded in cases where the defendant has not made any payments towards the debt.

Post-Judgment Interest

Post-judgment interest is the interest that accrues on a judgment debt from the date of judgment until the debt is paid in full. This type of interest is calculated based on the time period between the judgment date and the payment date.

Post-Judgment Interest Formula

Post-Judgment Interest = (Principal Amount × Daily Interest Rate × Number of Days) / 365

Where:

Principal Amount = The amount of the judgment debt
Daily Interest Rate = Annual interest rate divided by 365
Number of Days = Days between the judgment date and payment date

For example, if a judgment of $15,000 is entered on March 1, 2023, and the debt is paid in full on June 15, 2023, with an annual interest rate of 5%, the post-judgment interest would be calculated as follows:

Example Calculation

Number of days = (June 15, 2023 - March 1, 2023) = 95 days

Daily interest rate = 5% ÷ 365 ≈ 0.0137%

Post-judgment interest = ($15,000 × 0.0137% × 95) ÷ 365 ≈ $65.59

Post-judgment interest is typically awarded to the prevailing party to compensate for the time value of money lost during the collection process. It is important to note that post-judgment interest is calculated from the date of judgment, not from the date of the last payment.
