The Car Insurance Deductible Calculator estimates annual premium savings and estimated premium plus deductible expense from eligible repair cost per claim, deductible, baseline annual premium, quoted discount and expected claims per year. Replace the example values with your own deductible car insurance figures and recalculate after changing an assumption. Use it to compare scenarios, then verify any current rate or fee before acting.
Compare premium savings against what you would pay yourself for an eligible claim. Check that the policies have equivalent coverage before comparing costs.
Compare with a zero-deductible policy with otherwise identical coverage. Each claim is assumed to have the eligible repair cost entered here. The premium discount is your input, not an insurer offer.
Complete every field with a non-negative number. Premium must exceed 0 and the discount must be between 0 and 100%.

Understand the Deductible of Car Insurance
A deductible is the eligible loss you pay yourself before the insurer pays the remainder, subject to policy limits. Consider claim frequency and whether you can afford that payment when comparing premiums.
Deductible Formula
Out-of-pocket cost per claim = the smaller of eligible repair cost and deductible
Net savings with one claim = annual premium savings minus out-of-pocket cost
Years of premium savings needed to cover one claim = out-of-pocket cost divided by annual savings
Deductible options in Thailand
Use the deductible and discount from a written quote. Compare equivalent coverage and exclusions, and keep enough cash available to pay your share of a claim.
Frequently asked questions
What is a car insurance deductible?
The deductible is the amount that the insured must pay before the insurance company pays the remaining amount. For example, if the deductible is 5,000 baht and the total repair costs are 50,000 baht, the insurance company will pay 45,000 baht.
How does a higher deductible make premiums cheaper?
When the insurer accepts increased risk first (high deductible) insurance companies have reduced risk and offer premiums at a lower rate. Generally, increasing deductible 2,000-5,000 baht may reduce premiums 5-15% per year
Should I choose a high or low deductible?
Depending on driving behaviour and financial situation, if you drive carefully, trick less and have enough emergency reserve, a high deductible will save you interest in the long run, but if you trick often or have no reserve, a low deductible may be more appropriate.
What is the break-even analysis of Deductible?
Break-even is the number of times you'll be covered that makes choosing a high and low deductible cost the same. Calculated by savings per year divided by the difference between the deductible and the break-even.

Understanding your insurance estimate
Out-of-pocket cost per eligible claim is the smaller of repair cost and deductible. Annual cost is discounted premium plus expected claims multiplied by that out-of-pocket cost. Claim-frequency break-even is annual savings divided by out-of-pocket cost when it is positive.
Before comparing offers
The baseline has no deductible and otherwise identical coverage. Each claim has the entered eligible repair cost; exclusions and other excesses are not modeled.
