60/month vs 45/month over 10 years: 7,200 vs 5,400 = 1,800 gap. Assuming coverage is equivalent, switching saves 1,800 over a decade. Coverage comparison (exclusions, limits) matters as much as headline premium.

A worked example

Try the defaults: option a monthly of 60, option b monthly of 45, horizon of 10. The tool returns 1,800.00. 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 Option A Monthly, Option B Monthly, and Horizon. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.

The formula behind this

Monthly × 12 × years for each. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

What to do with a low result

A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.

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.

What to calculate alongside this

One figure by itself is fragile. The annual subscriptions audit calculator, the d and o insurance calculator, and the health insurance calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.

Example Scenario

Frequently Asked Questions

Cheaper always better?
Not always. Check coverage, excess, exclusions. A cheaper policy with bigger excess can cost more when claims hit.
How often to switch?
Annual review. Auto-renewal often raises premium 5-15% silently. Compare yearly.
Loyalty discount?
Rare now. Most insurers price new customers aggressively, loyalty not rewarded. Switch to win pricing.
Cancellation fees?
Check before switching mid-term. Usually minimal but can eat savings for short remaining periods.
