The break-even math for full coverage
Full coverage adds collision and comprehensive to your base liability policy. The question is whether the protection is worth the extra premium. The break-even calculation is straightforward: divide your maximum payout (vehicle value minus deductible) by the extra annual cost for full coverage. If you would need to collect on the coverage within that many years to break even, you can assess whether the risk is worth it.
Depreciation changes the math over time
A new car loses 20-25% of its value in the first year. By year five, many vehicles have lost 50-60% of their original value. Yet insurance premiums do not drop at the same rate. This means the ratio of cost to benefit for full coverage gets worse every year you keep an aging vehicle. Revisit this calculator every 12 months to see if dropping to liability now makes sense.
One more thing: your financial situation
The break-even math assumes you could absorb a total loss if you dropped full coverage. If losing your $9,000 car would create a financial hardship — no emergency fund, no way to replace transportation — full coverage may be worth carrying even if the math is borderline. The formula optimizes for expected value, not financial resilience.
