Collection Insurance Coverage Calculator
Estimate the recommended insurance coverage amount for your personal collection (art, jewelry, coins, stamps, sports cards, etc.) based on its appraised value, desired deductible, and coverage type.
Formulas Used
1. Projected Future Value:
FV = Current Value × (1 + Appreciation Rate)Years
2. Base Coverage:
Base Coverage = FV × Coverage Multiplier
• Agreed Value: 1.00 (100%)
• Replacement Cost: 1.10 (110%)
• Actual Cash Value: 0.80 (80%)
3. Net Recommended Coverage:
Net Coverage = Base Coverage − Deductible
4. Estimated Annual Premium:
Premium Range = Net Coverage × 1% to Net Coverage × 2%
5. Coverage Gap:
Gap = max(0, Projected Value − Net Coverage)
Assumptions & References
- Coverage multipliers are based on standard scheduled personal property (floater) insurance practices in the U.S.
- Replacement Cost coverage uses a 10% buffer above appraised value to account for market appreciation between appraisals (Insurance Information Institute).
- Actual Cash Value applies an 80% factor reflecting typical depreciation adjustments by insurers.
- Annual premium benchmarks of 1%–2% of insured value are industry-standard estimates for collectibles riders/floaters (Chubb, AXA Art, Berkley One).
- Collections should be professionally appraised every 3–5 years; more frequently for volatile markets (coins, art, sports memorabilia).
- This calculator does not account for individual insurer underwriting criteria, location-based risk factors, or bundling discounts.
