Ontario Calculator

Ontario Small Claims Claim Value Estimator

Estimate the net principal, optional prejudgment interest, and other economic figures for a proposed Ontario Small Claims Court claim, and check the amount that counts toward the $50,000 monetary jurisdiction. Interest, court fees, disbursements, and representation costs are excluded from the jurisdiction figure.

Inputs

All amounts in Canadian dollars (CAD).

Principal damages or debt claimed (CAD)

The main amount you say you are owed - unpaid invoice, loan, deposit, or damages figure. Interest and court costs go in the separate fields below.

Other proven monetary losses

Extra out-of-pocket losses on top of the principal - for example, storage costs, towing, or replacement rental. Add one row per item.

Payments / credits received

Amounts the defendant has already paid or credited against the debt. These reduce the net principal that counts toward the $50,000 jurisdiction ceiling.

Estimate prejudgment interest (simple)

Court costs and representation (not counted toward $50,000)

These figures appear in the practical total for planning but are excluded from the $50,000 monetary jurisdiction under s. 23 of the Courts of Justice Act.

Court fees incurred (CAD)

Other disbursements (CAD)

Representation-cost assumption (CAD)

Estimate

1. Jurisdiction check

Amount counted toward the $50,000 monetary jurisdiction: $0.00

Under the Small Claims Court monetary jurisdiction. Interest and costs are extra and are not counted here.

2. Practical figure (planning only, not the jurisdiction test)

Gross principal (damages + losses): $0.00
Payments credited: -$0.00
Net principal (counts toward $50,000): $0.00
Prejudgment interest (estimate, not counted): $0.00
Court fees + other disbursements (not counted): $0.00
Representation-cost assumption (not counted): $0.00
Total practical figure (planning estimate): $0.00

This total is a planning number only. It is not the amount used to decide whether a case fits within the Small Claims Court - only the net principal above is compared to the $50,000 limit.

Estimate only - not a court determination. Representation costs are a user-entered assumption and are not automatically recoverable.

About this calculator

The Small Claims Court's monetary jurisdiction is $50,000, excluding interest and costs. This calculator adds the principal claim, any other proven monetary losses, and subtracts payments credited to produce a net principal. Only that net principal is compared to the $50,000 limit.

Prejudgment interest is reported separately using the same simple-interest engine as our Court Interest Calculator. Court fees, other disbursements, and any representation-cost assumption are shown in the economic total but do not count against the jurisdiction ceiling.

Worked example

A claimant sues for $28,000 in unpaid invoices plus $1,200 in storage costs. The defendant paid $3,000 in November 2025. Net principal is $26,200 - well under $50,000.

Adding an estimated 5% simple interest for the year to July 2026, plus a $108 filing fee and $120 in service costs, the total economic amount rises above $27,000 but the jurisdiction figure stays at $26,200.
