Should you raise your deductible?

“Raise your deductible to save money” is one of the most common pieces of insurance advice. It’s also one of the worst-explained.

The advice is correct, but the actual math is rarely shown. Here’s how to do it for yourself.

The basic mechanic

Your deductible is what you pay out of pocket before your insurance pays anything. Common auto deductibles are $250, $500, $1,000, and $2,500. Home is typically $1,000, $2,500, or $5,000.

The trade-off: a higher deductible means a lower premium, in exchange for more out-of-pocket exposure if you have a claim.

The savings curve

Insurers price the deductible-vs-premium trade-off through actuarial tables, but the curve is roughly:

Auto insurance:

• $250 → $500: typically saves 5-10% of premium
• $500 → $1,000: typically saves 10-15%
• $1,000 → $2,500: typically saves 15-20%
• $2,500 → $5,000: typically saves another 10-15%

Homeowners:

• $500 → $1,000: typically saves 8-12%
• $1,000 → $2,500: typically saves 12-18%
• $2,500 → $5,000: typically saves another 10-15%
• $5,000 → $10,000: typically saves another 10-15% (in some markets)

These are ranges. The actual savings depend on your specific carrier, state, and risk profile.

The math

Let’s run actual numbers.

Example: You currently pay $1,800/year for auto with a $500 deductible. Your carrier offers a $1,000 deductible option for $1,575/year.

• Annual savings: $1,800 - $1,575 = $225
• Increased exposure per claim: $1,000 - $500 = $500

Payback math: $500 ÷ $225 = 2.2 years.

If you go more than 2.2 years between at-fault claims that you’d file, you’re ahead. If you have claims more often than that, you’re behind.

For most drivers, the math strongly favors the higher deductible. Industry data suggests the average driver files an at-fault collision claim every 17-18 years. Most years pass without a claim.

The “can you afford it” filter

Math doesn’t tell you whether to raise the deductible — your cash situation does.

The rule: only raise the deductible if you can comfortably write a check for it tomorrow. Specifically:

• The full deductible amount, plus
• Without touching your emergency fund (which exists for other emergencies)
• Without putting it on a credit card

If you can pass that test, raise the deductible. The savings are real, and the increased exposure is manageable.

If you can’t, keep the lower deductible. The premium savings aren’t worth the risk of being unable to pay it at claim time. (Or — start building the savings now, and revisit in 6 months when you can.)

Where high deductibles really pay off

The deductible-savings math gets especially attractive in two situations:

1. You almost never file claims.

If you’re a careful driver with a long claim-free history, the probability of filing each year is low. Higher deductible saves money you’d otherwise have paid in premium for coverage you didn’t use.

2. Your home is in a low-claim area.

If you live in a stable climate zone, away from hail-and-wind belts, hurricane corridors, and wildfire risk areas, your probability of a homeowners claim is low. A $5,000 deductible can save several hundred dollars a year vs. a $1,000 deductible.

Where low deductibles still make sense

1. You have unstable cash flow.

If finding $1,000 unexpectedly would force you onto credit cards or into other debt, a lower deductible is worth the higher premium.

2. You’re in a high-claim risk area.

If you’re in a hail zone, wildfire zone, or hurricane corridor, claims are not “rare events.” A higher deductible there means real out-of-pocket exposure every few years.

3. The savings are small.

Sometimes the deductible jump only saves 5-7% — not worth the increased risk. Always price the comparison; don’t assume the higher deductible is meaningfully cheaper.

Specific to homeowners: hurricane and wind deductibles

A lot of homeowners policies in coastal states have separate wind/hurricane deductibles, often expressed as a percentage of dwelling coverage (1%, 2%, 5%). On a $400,000 dwelling, a 5% hurricane deductible is $20,000.

These are usually not optional — they’re imposed by the carrier on policies in hurricane-exposed states. Verify your wind/hurricane deductible separately from your standard “all peril” deductible.

How to actually request the change

For most carriers, you can:

1. Log into your account online and adjust the deductible directly
2. Call your carrier and request the change
3. Use it as a reshop opportunity — get fresh quotes from competitors at the new deductible level

The change typically takes effect at your next renewal, though some carriers will adjust mid-term and prorate.

The shopping angle

Don’t change your deductible without re-shopping. Sometimes a different carrier is significantly cheaper at the same deductible level you have now — and that’s a bigger win than raising your deductible with your current carrier.

The full optimization is:

1. Get quotes from 5 carriers at your current deductible
2. Get quotes from the cheapest 2-3 at a higher deductible
3. Compare total annual cost AND your exposure at claim time
4. Pick the combination that fits your cash situation

TL;DR

• Raising your deductible saves real money
• The savings typically pay back the increased exposure in 2-4 years
• Only raise it if you can comfortably write a check for the full deductible tomorrow
• Always shop carriers at the same time you change deductibles — the bigger win is often choosing a different carrier

The right deductible isn’t a universal answer. It’s whatever balance lets you pay the lowest sustainable premium without risking financial pain at claim time.
