Free Ontario Civil Litigation Calculators
Before you sue — or decide whether a lawsuit is even worth it — the questions that matter most are about money and odds: What will this cost me? How much is my claim actually worth? Should I take the settlement offer or go to trial? Have I already run out of time to sue? Our free Ontario civil litigation calculators answer exactly these questions, using the rules that govern civil disputes here — Small Claims Court and the Superior Court of Justice, the Limitations Act, 2002, and Ontario’s costs regime. There is no cost, no sign-up, and no obligation — just a fast, realistic estimate so you can make a clear-eyed decision before spending a dollar on litigation.
Civil litigation in Ontario is procedure-heavy, and the economics are where cases are won or lost long before trial. Court costs, recoverable fees, interest, and the two-year limitation clock all shape whether a claim is worth pursuing. These tools turn that math into numbers you can act on.
What You Can Estimate
Cost, Court & Claim Value
Start with the Civil Lawsuit Cost Calculator to estimate what pursuing a claim will cost by court, stage, and complexity, and the Civil Claim Value Estimator to add up your heads of loss — direct, consequential, out-of-pocket, and interest. Not sure where your case belongs? The Small Claims or Superior Court?tool points you to the right forum based on the amount in dispute and the remedy you need.
Debt, Interest & Deadlines
For money owed under an agreement, the Contract Debt & Interest Calculator estimates the outstanding balance plus interest, and the Demand Letter Amount Calculator totals principal, interest to date, and recoverable costs so your demand letter lands with the right number. Because the clock is often the first thing to check, the Limitation Period Calculator estimates your deadline to sue under the two-year basic limitation period and the 15-year ultimate deadline.
Costs Recovery & Settle-or-Trial
Winning isn’t free, so the Legal Costs Recovery Calculator estimates how much of your fees you might recover — partial indemnity in the Superior Court or the Small Claims cost cap. And when there’s an offer on the table, the Settlement vs. Trial Calculator weighs it against the expected value of going to trial, using your odds and your cost to get there.
Why Use an Ontario-Specific Calculator
Civil procedure is provincial, and Ontario’s rules are specific: a $50,000 Small Claims ceiling above which claims proceed in the Superior Court, partial-indemnity costs that typically recover only part of your fees, pre-judgment interest set under the Courts of Justice Act, and a two-year limitation period with limited exceptions. A generic estimator won’t know any of that. Our tools are built around those rules, so your estimate reflects how an Ontario court would actually treat your claim.
- Built on Ontario’s rules — Small Claims and Superior Court, the Limitations Act, and the costs regime.
- 100% free and private — no account, no payment, nothing shared.
- Decide before you sue — weigh cost, recovery, and odds before you commit.
- Plaintiff or defendant — the same tools help you press or defend a claim.
Litigation Is a Business Decision
A strong claim on paper can still be a poor investment if the cost to pursue it, the limited costs you can recover, and the risk of losing outweigh what you’d collect — especially if the other side may not be able to pay. That’s why running the cost, recovery, and settlement-vs-trial tools together matters: they turn a gut decision into a numbers-based one. Most civil disputes settle, and going in with a clear view of your claim’s value and your realistic net recovery is exactly what strengthens your hand in those negotiations.
An Estimate Is a Starting Point, Not Legal Advice
These calculators are designed to inform your decision, not to replace a lawyer’s judgment. They can’t weigh the strength of your evidence, a limitation argument specific to your facts, or the strategy that wins at a pre-trial or mediation. Use the numbers to plan and to ask sharper questions. When you’re ready to send a demand, file a claim, or defend one, our civil litigation lawyers can review your matter — often starting with a free consultation.
Common Questions
Civil Litigation Calculator FAQs
What is civil litigation?+
Civil litigation is the process of resolving non-criminal disputes between parties through the courts — for example, breach of contract, debt, negligence, and business disputes. Claims of $50,000 or less generally proceed in Small Claims Court; larger claims proceed in the Superior Court of Justice.
How long do I have to start a civil claim in Ontario?+
In most cases, two years from when you knew or ought to have known about the claim, under the Limitations Act, 2002. There is also a 15-year ultimate deadline. Missing the limitation period generally bars your claim, so use our Limitation Period Calculator and act promptly.
Can I recover my legal costs if I win?+
Usually only a portion. In the Superior Court, a successful party generally recovers partial-indemnity costs — often around 50–60% of reasonable fees. In Small Claims Court, the representation-fee award is generally capped at 15% of the claim. Our Legal Costs Recovery Calculator estimates this.
Are these calculators legal advice?+
No. These tools give general estimates only and are not legal or financial advice. Actual outcomes depend on the facts, the evidence, and the law. For advice tailored to your situation, speak with a lawyer — our civil litigation team offers a free consultation.
Are these civil litigation calculators free to use?+
Yes. Every calculator on this page is completely free, with no sign-up, no payment, and no obligation. You can estimate cost, claim value, interest, deadlines, and settlement value privately before deciding whether to pursue a claim.
Which calculator should I use first?+
If you're deciding whether to sue, start with the Limitation Period Calculator (do you still have time?), then the Civil Claim Value Estimator and the Civil Lawsuit Cost Calculator to weigh what you could recover against what it will cost.
What is the difference between Small Claims Court and the Superior Court?+
Small Claims Court handles claims of $50,000 or less and is faster, cheaper, and more accessible to self-represented parties. Larger claims and certain remedies proceed in the Superior Court of Justice, which is more formal and expensive. The Small Claims or Superior Court? tool helps you choose.
How much does it cost to sue someone in Ontario?+
It varies widely by court, complexity, and how far the case goes. Small Claims matters can be relatively modest, while a Superior Court action that reaches trial can run into the tens of thousands. The Civil Lawsuit Cost Calculator estimates the range for your situation by stage.
How much interest can I add to money I'm owed?+
If your contract sets an interest rate, that generally governs. Otherwise, courts award pre-judgment interest at the rate set under the Courts of Justice Act, and post-judgment interest continues after judgment. The Contract Debt & Interest Calculator estimates the balance plus interest owed.
Should I send a demand letter before suing?+
Usually yes. A clear demand letter setting out what you're owed — principal, interest, and recoverable costs — often prompts payment or settlement without litigation, and shows the court you acted reasonably. The Demand Letter Amount Calculator helps you set the right figure.
Is it better to settle or go to trial?+
It depends on your odds of winning, the amount at stake, and your cost to reach trial. A settlement is certain; a trial is not, and even a win rarely recovers all your fees. The Settlement vs. Trial Calculator weighs a specific offer against the expected value of proceeding.
Can I represent myself in a civil case?+
Yes. Individuals can self-represent in both Small Claims Court and the Superior Court, and licensed paralegals can represent parties in Small Claims Court. For higher-value or complex Superior Court matters, a lawyer is strongly advisable given the procedural and evidentiary demands.
