Compare a Higher Car Insurance Deductible With the Savings It Requires
A higher deductible can change the amount of cash you need even when the premium falls.
In this guide
A higher deductible can change the amount of cash you need even when the premium falls.
How to approach the decision
Use the premium and deductible from the same written quote. Compare both the recurring premium cost and how much additional cash you need to set aside to reach the new target.
Worked example
| Input | Example |
|---|---|
| Monthly loan payment ($) | $480.00 |
| Annual insurance premiums ($) | $1,580.00 |
| Target deductible reserve ($) | $1,500.00 |
| Already reserved ($) | $250.00 |
| Months to save | 6 |
| Result | Estimate |
|---|---|
| Monthly loan and premium budget | $611.67 |
| Monthly deductible reserve contribution | $208.33 |
| Annual premiums and loan payments | $7,340.00 |
Averages annual premiums over 12 months and spreads the unfunded deductible across your savings period. Use the deductible for the specific coverage you are planning around.
What to verify
Ask whether the lender sets coverage requirements for the financed vehicle. Compare the actual quotes using the same coverage limits where possible.
