What this calculator does
Choosing a higher deductible on an insurance policy usually lowers the annual premium, in exchange for paying more out of pocket if a claim is ever made. This calculator works out how many years of that premium saving it takes to offset the extra amount that would need to be paid once, if a claim happens.
The trade-off is essentially a bet on whether a claim will be made before that break-even period is up. It does not, and cannot, predict whether a claim will actually occur; it simply states the arithmetic of the trade-off so that choice can be made deliberately rather than by guesswork.
The formula
Divide the increase in the deductible by the annual premium saved from choosing it. The result is the number of years of savings needed to fully offset paying that higher deductible once.
| Term | Meaning |
|---|---|
| Years to break even | How long the premium savings take to offset the deductible increase: deductible increase ÷ annual premium savings. |
| Deductible increase | How much higher the new deductible is than the current one. |
| Annual premium savings | How much less the annual premium is at the higher deductible. |
The inputs explained
| Field | What to enter |
|---|---|
| Increase in deductible ($) | The dollar increase between the current deductible and the higher one being considered. |
| Annual premium savings from higher deductible ($) | How much lower the annual premium is at that higher deductible, compared with the current policy. |
When to use it
Deciding whether to raise a deductible
A short break-even period, such as under two years, makes a higher deductible an easier decision for someone confident they can absorb an out-of-pocket cost if a claim does happen.
Reviewing a policy at renewal
When an insurer offers a lower premium for a higher deductible at renewal, this calculation turns that offer into a concrete number of years, rather than a vague sense that a higher deductible "saves money".
Weighing risk tolerance against savings
Someone with a smaller emergency fund may reasonably prefer a lower deductible even with a longer break-even period, since the higher deductible poses more risk to their finances if a claim happens early.
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How years to break even change with the size of the deductible increase
A fixed $120 in annual premium savings, across a range of deductible increases.
How years to break even change with annual premium savings
A fixed $500 deductible increase, across a range of annual premium savings.
Questions
What happens if I never make a claim during that break-even period?
The full amount of premium savings is kept, since the higher deductible was never actually paid. Every year beyond the break-even point is pure savings compared with staying on the lower-deductible, higher-premium policy.
What happens if I make a claim before break-even is reached?
The higher deductible costs more out of pocket in that claim year than the premium savings collected up to that point, so the higher-deductible choice comes out behind for that period, though it may still be worthwhile over a longer horizon if no further claims occur.
Is a shorter break-even period always better?
A shorter break-even period means the higher deductible pays off sooner if no claim occurs, but it says nothing about how likely a claim actually is. That likelihood, and how easily the higher deductible could be covered in cash if needed, matters as much as the break-even period itself.
Should this decision be made on the numbers alone?
The numbers show the mechanics of the trade-off, but the right choice also depends on how comfortable someone is carrying that risk and whether they could pay the higher deductible without financial strain if a claim did happen. A licensed insurance professional can help weigh those factors alongside the arithmetic.
