Deductible Decision Tool

Decide between two deductibles on any policy by comparing the annual saving against the extra exposure it creates.

Whatever the line of business, the deductible decision is identical: a small certain saving now against a larger uncertain cost later. Auto, home, commercial property and health policies all present the same trade in different clothing.

This tool compares two options on that basis and reports how many claim-free years the saving needs before it covers the extra exposure - plus what happens if a claim arrives sooner.

This is an estimate based on the values you entered. Actual premiums, coverage, eligibility and pricing vary by provider and by individual circumstances.

The higher deductible pays for itself in 4.5 claim-free years. Choosing it only makes sense if you can pay the extra 1000 out of pocket on short notice.

How to use the deductible decision tool

  1. Enter the annual premium and deductible for the option you have now.
  2. Enter the same for the option you are considering.
  3. Set a horizon that matches how long you expect to hold the policy.
  4. Read the break-even and the scenarios, then check the reserve you keep on hand.

What people use this for

  • Choosing a deductible on any new policy.
  • Deciding whether to raise a deductible to offset a renewal increase.
  • Comparing two quotes whose deductibles differ as well as their prices.
  • Explaining the trade-off to someone else with specific numbers.

Break-even, and what it does not tell you

The break-even is the number of claim-free years the saving needs to cover the extra exposure. Under about three years is comfortable for anyone who claims rarely; beyond five or six the carrier is not paying you much for the risk.

What it cannot tell you is whether you can pay the deductible. Expected value assumes every outcome is affordable, and the whole point of insurance is that some are not.

The liquidity test comes first

If the deductible amount is not sitting in an accessible account, the lower deductible is the right choice whatever the arithmetic says. A deductible funded by borrowing converts an insurance problem into a debt problem.

Once that constraint is satisfied, the break-even decides the rest - and for households with a genuine emergency fund, higher deductibles are usually the better long-run choice.

Methodology and assumptions

What this calculator does, and what it deliberately does not do.

  • Break-even years = extra deductible exposure ÷ annual premium saving.
  • Scenarios subtract the extra exposure once or twice from the accumulated saving across the horizon. Claim frequency is not predicted.
  • Percentage deductibles must be converted to a dollar amount before being entered.
  • All figures are estimates produced from the values you enter. This site has no rate feed and no carrier data, so it cannot quote or price a policy.
  • Nothing you type is transmitted or stored - the calculation runs entirely inside your browser.

Frequently asked questions

Does this work for any line of insurance?

Any line with a per-claim deductible. Policies with an annual aggregate deductible behave differently and need separate treatment.

What about percentage deductibles?

Multiply the percentage by the insured value first, then enter the resulting dollar amount as the higher deductible.

Should I use the same deductible on every policy?

There is no need to. Frequency differs by line, so the right answer for auto collision is frequently different from the right answer for a property policy.

Is a low deductible ever the better financial choice?

When the premium saving from raising it is small, or when the deductible could not be funded without borrowing. Both are common.
