Settle or Go to Court?
Ontario Calculator.
Holding a settlement offer and not sure whether to take it? This tool weighs the offer against the risk-weighted value of trial — your odds of winning, prejudgment interest, recoverable costs, your own legal bill, and the real risk of collecting a judgment. Works for both sides of the case. Updated for 2026.

Weigh the offer against the odds
A settlement is a bird in the hand; a trial is two in the bush — sometimes. The rational way to choose is to put a number on each. Tell the calculator what a win is worth, how likely it is, what a loss would cost, and how confident you are of collecting, and it computes the risk-weighted value of going to court and sets it beside the offer on the table.

Weigh a settlement offer against the risk-adjusted value of trial. Fields marked with * are required.
How do you decide whether to settle or go to court?
Compare the settlement offer against the risk-weighted value of trial — what a win is worth multiplied by your realistic odds of winning, minus what a loss and the cost to finish the case would cost you. The instinct in a dispute is to compare the offer to the full amount claimed — "they're offering $12,000 but I'm owed $20,000, so no deal." That comparison is a trap, because it assumes you win, win in full, and collect every dollar. A lawsuit isn't a sure thing. The honest comparison prices in the chance you lose, the money it will take to get to judgment, and the chance a judgment actually turns into cash.
What is the expected-value formula?
Expected value of trial = (chance you win × what a win nets you) + (chance you lose × what a loss costs you)
For a plaintiff, "what a win nets you" is the award plus prejudgment interest plus the costs you recover — multiplied by your chance of actually collecting — minus your own legal bill. "What a loss costs you" is your own legal bill plus the costs you'd owe the other side. Compare the result to the settlement offer.
Which inputs decide the outcome?
Six numbers drive the result: the amount in play, your odds of winning, the cost to finish the case, the winner's cost award, your odds of collecting, and — for context only — what you've already spent.
| Input | Why it matters |
|---|---|
| Amount in play | What a judge would award if the claim fully succeeds — the ceiling on a win, or the exposure on a loss. |
| Chance of winning | Your sober estimate of success at trial. Most contested cases live between 40% and 70% — certainty is rare. |
| Cost to finish the case | Legal fees and disbursements from today to judgment. This is the money settling would save you — the cost the decision actually turns on. |
| Costs already spent | What you've paid so far. It's a sunk cost — gone whether you settle or fight — so it's shown for context but left out of the math. |
| Cost award | What the loser pays the winner — capped near 15% of the claim in Small Claims Court (CJA s. 29). |
| Chance of collecting | A win on paper is worth nothing against a defendant who can't or won't pay. This discounts the trial value. |
Should the money I've already spent affect the decision?
No — legal fees you've already paid are a sunk cost, and sunk costs should not drive the settle-or-sue decision. That money is gone whether you accept the offer or push to trial, so it's the same in both worlds and cancels out of the comparison. The only cost that matters now is the cost to finish — what you'd spend from today to judgment, which settling lets you avoid. This is why the calculator asks for the two separately and scores only the cost to finish. The trap it protects you from is the gambler's instinct — "I've already sunk $8,000 into this, I can't stop now" — which pushes people to spend good money chasing bad. The honest question is always forward-looking: from here, is another dollar of trial cost worth more than the offer on the table?
Why can a smaller settlement beat a bigger claim?
Because the offer is certain and immediate, while the bigger number is only a possibility discounted by the odds, the cost to get there, and the risk of never collecting. Say you're owed $20,000, you think you'd win 60% of the time, it would cost $6,000 to finish the case, and you're confident of collecting. A win nets roughly the award plus interest and recovered costs, less that cost to finish; a loss costs the cost to finish plus the other side's costs. Blend those by the odds and the risk-weighted value of trial often lands below a clean settlement in the low-to-mid teens — before you even count the months of stress.
Can an offer to settle change the costs a judge awards?
Yes — a formal offer to settle can up to double the costs the judge awards, so it can flip a marginal case. Under Rule 14.07 of the Rules of the Small Claims Court, a party who makes a written offer to settle and then matches or beats it at trial can be awarded up to twice the costs it would otherwise get. This calculator deliberately doesn't model that doubling, because whether it applies turns on the timing and wording of the offer — details best assessed by a lawyer. If a formal offer is on the table, factor it in separately.

Is it better to settle or go to trial?
Settling is better when the offer beats the risk-weighted value of trial or when you value certainty and finality; trial is better when the odds, amounts, and your ability to collect clearly outweigh the offer and the cost to get there. The dollars are only half the decision. A settlement buys certainty, speed, and finality: money now, no trial, no risk of an adverse costs award, and no enforcement fight. A trial offers the chance of a full recovery — and the chance of a total loss, a costs order against you, and a judgment you still have to collect. Where you sit between those poles depends on how much a bad outcome would hurt and how much the certainty is worth to you.

Settle-or-sue FAQ
Should I settle or go to court in Ontario?
Compare the settlement offer against the risk-weighted value of trial: multiply what you'd win by your realistic chance of winning, add recoverable interest and costs, subtract what a loss would cost you and your own legal fees, and discount for the chance you actually collect. If the offer beats that expected value, settling is usually the rational choice. It's a decision aid, not a prediction of your one case — a Small Claims Court lawyer can weigh the factors a formula can't.
How do you calculate the expected value of a lawsuit?
Expected value weights each outcome by its probability. For a plaintiff: (chance of winning × (award + prejudgment interest + recoverable costs) × chance of collecting) minus (chance of losing × the costs you'd owe) minus your own legal costs to run the case. Compare that figure to the settlement offer on the table. A positive gap means trial is worth more on average; a negative gap means the offer is the better bet.
What is a risk-weighted settlement decision?
A risk-weighted decision prices in uncertainty instead of assuming you win. Because a lawsuit can end in a win or a loss, the sensible comparison isn't "how much could I win?" but "how much is this worth on average, once the odds, the costs, and the risk of collecting are all accounted for?" A settlement offer that beats that risk-weighted number is often worth taking even when it's less than the full claim.
Does an offer to settle change the costs a judge awards?
Yes. Under Rule 14.07 of the Rules of the Small Claims Court, a party who makes a written offer to settle and then does as well or better at trial can be awarded up to twice the costs it would otherwise receive. A well-timed formal offer can swing the costs outcome significantly. This calculator doesn't model that doubling, so get advice before relying on the numbers if an offer to settle is in play.
Why does collecting a judgment matter to the settle-or-sue decision?
Winning and getting paid are two different things. A judgment against a defendant who is insolvent, uninsured, or hard to locate can be worth little after the cost of enforcement. Because a settlement is usually paid on signing, guaranteed money now can beat a larger judgment you may never collect. The calculator lets you discount the trial value by your realistic chance of collecting. Our debt collection page covers enforcement.
What does going to trial cost that a settlement avoids?
Beyond your own legal fees and disbursements, a contested trial takes months to years, demands your time and documents, and carries the stress and uncertainty of an all-or-nothing result. Even when the dollar math favours trial, those non-monetary costs — which this tool flags but doesn't price — often tip a close call toward a reasonable settlement.
Should I factor in the money I've already spent on the case?
No. Legal fees you've already paid are a sunk cost — the same whether you settle or go to trial — so they shouldn't drive the decision. Only the cost to finish the case from today matters, because that's the money settling would save you. The calculator asks for costs already spent and cost to finish separately, and scores only the cost to finish, so you're not pushed into the sunk-cost trap of spending good money after bad.

About this tool — please read
This page provides general legal information and a simplified decision model for educational purposes only. It is not legal advice, does not account for the specific facts, evidence, or law that govern your dispute, and creates no lawyer–client relationship. The expected-value figures are an average across many similar cases — your case resolves once, on a win or a loss, not on the blended number shown. The model does not capture every variable: it excludes the potential doubling of costs after an offer to settle (Rule 14.07), the court's discretion over costs and interest, partial or split outcomes, appeals, and the time, effort, and stress of litigation. No warranty is given as to accuracy. Consult a qualified Ontario lawyer about your specific situation before you accept, reject, or make a settlement offer.
