Calculation Results
Annual Auto Insurance Budgeting Model
Net Premium = Base Premium × (1 − Discount Percentage) | 5-Year Expense = Annual Premium × 5- Multi-Policy & Driver Discounts: Multi-car (~12%) and safe driver (~10%) discounts can lower premiums by 20% to 25%.
- Deductible Sensitivity: Raising your collision and comprehensive deductible from $500 to $1,000 typically reduces premiums by 10% to 15%.
Step-by-Step Worked Example
Scenario: Full coverage insurance with a $165/month premium, multi-car discount, and comparing deductibles
Calculation Steps:
- Annual Net Premium = $165.00 × 12 = $1,980.00
- 5-Year Projected Outlay = $1,980.00 × 5 = $9,900.00
- Raising Deductible to $1,000 saves ~12% ($237.60 / year)
- Lowering Deductible to $250 increases cost by ~15% ($297.00 / year)
Result: Annual insurance is $1,980 ($9,900 over 5 years). Raising your deductible to $1,000 saves $237.60 every year.
