Insurance Deductible Break-Even Calculator

Updated April 20, 2026 · Financial Health · Educational use only ·

Claims per year where a higher deductible breaks even with lower premium.

Find the number of claims per year where higher deductible with lower premium breaks even with low deductible. Instant result with methodology shown.

What this tool does

Higher deductibles mean lower premiums but more out-of-pocket per claim. Enter annual premium savings from higher deductible and the deductible difference. The tool returns how many claims per year would need to happen for the low-deductible plan to break even.

200 annual premium savings with a 500 deductible increase: one extra claim in 2.5 years tips the balance. If you claim less often than once every 2.5 years, the high-deductible plan wins. More often, low deductible is better.

Rule of thumb

If your break-even is less than 1 claim every 2-3 years, the low-deductible plan is usually better if claims are common in your category. For car/home insurance where claims are rare (under one per 3 years for most people), high-deductible typically wins the cash math.

A worked example

Try the defaults: annual premium savings of 200, deductible difference of 500. The tool returns 0.4 claims/yr. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Annual Premium Savings (Higher Deductible) and Deductible Difference. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

The formula behind this

Break-even claims is annual premium savings divided by deductible difference. Ignores claim probability distribution — treats claims as deterministic. Real expected value needs actuarial probability data. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Using this as a check-in

Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

Break-even claims per year between deductible options is shown above.

Inputs

Annual Premium Savings (Higher Deductible):£200
Deductible Difference:£500
Expected Result0.4 claims/yr

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Break-even claims is annual premium savings divided by deductible difference. Ignores claim probability distribution — treats claims as deterministic. Real expected value needs actuarial probability data.

Frequently Asked Questions

What claim rate is realistic?
Home insurance: ~1 claim per 5-10 years typical. Car: ~1 per 3-5 years. Health varies hugely. Most people claim less than once a year, which usually favours higher deductibles.
Does this include claim severity?
No — assumes each claim hits the full deductible. Small claims often don't; large claims always do. Real expected cost needs probability-weighted analysis.
What's the risk of high deductible?
Having to fund a 1,000+ out-of-pocket cost immediately. If you don't have the cash reserves, a low deductible is insurance against insurance cost. Peace of mind has real value.
When does low deductible always win?
When premium savings are negligible relative to the deductible increase, or when you claim very frequently (multi-vehicle households, homes with history of claims).
