| Item | Current | New |

| Fees (12 months) | $30.00 | $30.00 |

Use annualized totals to avoid term-length bias. Suppose your current premium is $1,200 and fees are $30 for a 12‑month term. The annualized current cost is $1,230. If a new quote starts at $1,050 with the same $30 fees, the starting annualized cost is $1,080 before discounts. After discounts, the modeled new annual cost can drop further, creating clear savings per year and per month.
Percent discounts are combined and capped at 100%. A 5% safe‑driver discount plus a 10% bundle discount yields 15% total. Applied to a $1,050 base premium, the discounted premium becomes $892.50. Fixed credits reduce the premium after percent discounts, and coverage changes then adjust the total. Keep estimates conservative, because some insurers apply discounts to selected coverages only.
Installments can increase total cost even when the headline premium looks lower. If monthly billing adds a $5 installment fee, you pay eleven extra fees per year, or $55. Quarterly billing would add three fees, or $15. The calculator applies installment fees only to payments after the first, which matches many billing practices. Enter the fee from your declarations page to avoid underestimating cost.
Raising the deductible often reduces premium, but it increases out‑of‑pocket exposure. If you move from $500 to $1,000, the deductible increase is $500. Break‑even claim probability is AnnualSavings ÷ DeductibleIncrease. With $187.50 savings, break‑even is 37.50%. Below that probability, the higher deductible tends to improve expected cost; above it, the extra deductible can erase savings.
Expected cost adds the deductible weighted by claim probability. With an 8% annual claim probability, expected deductible cost is 0.08 × deductible. Current adds $40 and new adds $80, lowering risk‑adjusted savings by $40. Use this view when comparing aggressive deductible increases, telematics programs, or coverage cuts, and revisit assumptions every renewal cycle.
For planning, run three scenarios: optimistic discounts, realistic discounts, and worst‑case fees, then choose the safest option for you.
Use the term premium from your declarations page and add known policy fees. If your term is six months, enter six‑month totals so annualizing stays accurate.
Not always. Some discounts apply only to specific coverages or vehicles. Model the best estimate you can, then compare your results against the insurer’s quote breakdown.
Installment fees raise the effective cost of paying monthly or quarterly. Enter the fee per extra payment, and the calculator adds it to the term total automatically.
It compares expected annual costs by adding claim probability multiplied by the deductible. This helps you see whether a higher deductible meaningfully increases expected cost.
It is the claim probability where annual premium savings equals the extra deductible. If your expected claim probability is higher than break‑even, the higher deductible may not be worth it.
Yes. Change the scenario name, run calculations, and export each result to CSV or PDF. Save them together to compare savings, expected cost, and assumptions.
