Formula Used

This calculator estimates a fair extended warranty price using expected claims, reserves, overhead, profit, and tax.

1. Annual claim probability
Annual Claim Probability = Base Failure Rate × Category Factor × Usage Factor × Age Factor × Year Deterioration Factor

2. Projected repair cost
Projected Repair Cost = Average Repair Cost × (1 + Inflation Rate)^{Year - 1}

3. Covered amount per year
Covered Amount = max(min(Projected Repair or Replacement Value, Claim Cap) − Deductible, 0)

4. Expected claim cost per year
Expected Claim = Annual Claim Probability × Covered Amount

5. Break-even cost
Break-even Cost = Total Expected Claims + Administration Fee + Reserve Amount

6. Recommended contract price
Recommended Price = (Break-even Cost + Target Profit) + Tax

FAQs

1. What does this calculator estimate?

It estimates a fair selling price for an extended warranty by combining expected repair exposure, deductibles, reserves, admin costs, profit targets, and taxes.

2. Why is product age included?

Older products usually face higher failure risk. The model raises annual claim probability as current product age increases, which can raise the recommended warranty price.

3. How does the deductible affect pricing?

A higher deductible reduces the covered amount paid by the contract provider. Lower covered exposure usually lowers expected claim cost and final recommended pricing.

4. What is the reserve margin?

Reserve margin is a safety buffer for unexpected claim volatility, higher service costs, or worse-than-expected reliability. It supports more conservative contract pricing.

5. Why compare planned selling price with recommended price?

The comparison shows whether your intended market price is likely above, near, or below the model’s calculated target, helping you review pricing discipline.

6. What does the loss ratio show?

Loss ratio compares expected claims to net contract revenue before tax. Higher values mean a larger share of revenue may be consumed by claim payments.

7. Can this calculator replace legal or actuarial review?

No. It is a planning tool for pricing discussions. Contract language, state rules, claim behavior, and provider obligations still require professional review.

8. Is this useful for service contracts and maintenance plans?

Yes. It can support many protection-style agreements where future repair or replacement exposure needs pricing, especially when deductibles and claim limits apply.
