Deductible Impact Calculator

Calculate whether raising your home or auto insurance deductible saves money in the long run. Shows annual premium savings, break-even period, and 10-year total cost comparison.

How This Calculator Works

  1. Set your policy details: Choose home or auto, slide to your current annual premium, and select your current deductible from the dropdown.
  2. Choose your proposed deductible: Select the deductible you are considering. Results update instantly -- no submit button needed.
  3. Read the three key numbers: Annual premium change, break-even months, and 10-year net impact give you a complete picture of the tradeoff.

Estimate Formula

Annual Premium Change:
  New Annual Premium = Current Premium x (New Deductible Factor / Current Deductible Factor)
  Saving = Current Annual Premium - New Annual Premium

Break-Even Period (months):
  Break-Even = (New Deductible - Current Deductible) / Annual Saving x 12

10-Year Net Cost:
  Option Cost = (Annual Premium x 10) + (Expected Claims x Deductible)
  Net Impact   = Current Option Cost - New Option Cost

Frequently Asked Questions

Should I raise my insurance deductible?

Raising your deductible typically lowers your premium but increases your out-of-pocket cost if you file a claim. The decision depends on how likely you are to file a claim and how many months of premium savings it takes to offset the higher deductible -- the break-even period.

How much does raising a home insurance deductible save?

According to the Insurance Information Institute, raising a home deductible from $500 to $1,000 typically saves 7-10% on your annual premium. Going from $500 to $5,000 can save up to 28%.

What is a break-even period for a deductible change?

The break-even period is how many months of premium savings it takes to cover one extra deductible payment. If you raise your deductible by $500 and save $20/month, your break-even is 25 months. If you go claim-free that long, you come out ahead.

How does a deductible affect my premium?

Deductibles and premiums have an inverse relationship: a higher deductible means the insurer pays less per claim, so your premium goes down. The relationship is not linear -- the savings are largest when going from very low to moderate deductibles.

What deductible should I choose for home insurance?

Most financial advisors recommend choosing the highest deductible you could comfortably pay out of pocket without financial hardship. A common rule is to set your deductible equal to 1-3 months of savings.

The Inputs, Field by Field

Current premium and deductible. Enter your current annual premium and deductible so the calculator can model how changing the deductible shifts your premium and your risk.

Proposed deductible. Choose a higher or lower deductible to compare. A higher deductible lowers the premium but raises what you pay out of pocket at claim time.

How to Read Your Estimate

The result shows the premium change against the extra out-of-pocket risk you take on. The key figure is the break-even: how many claim-free years the premium savings would take to offset the higher deductible if you had one claim. If you rarely file claims and could comfortably cover the higher deductible, raising it usually wins; if a large out-of-pocket hit would strain you, the lower deductible buys peace of mind.

Assumptions and Limitations

This is an educational estimate, not a quote. The premium-to-deductible relationship varies by insurer and policy type, so your real savings may differ from the modeled figure. It does not account for claim frequency, policy-specific rules, or separate deductibles for perils like wind or hail. Confirm the actual numbers with your insurer.

More Frequently Asked Questions

Should I raise my deductible?

Raising it makes sense if you rarely file claims and could comfortably pay the higher amount after a loss. The premium savings then outweigh the added risk over time.

What is a break-even period?

It is how long the annual premium savings would take to equal the extra out-of-pocket cost of a higher deductible if you had one claim. A short break-even favors the higher deductible.

Do all policies have one deductible?

No. Home policies often have separate deductibles for perils like wind or hail, sometimes expressed as a percentage of the home's value rather than a flat amount.

About This Estimate

Premium reduction factors are derived from Insurance Information Institute published research on deductible-to-premium relationships, supplemented by state insurance department rate filings. The 10-year model uses actuarially expected claim frequencies for homeowners (approximately 1 per 9 years) and auto (approximately 1 per 5 years) as defaults, adjustable by the user.
