Quick guide

How to use this calculator

  1. Enter policy terms, losses, exposures, probabilities, reserves, or financial assumptions on a consistent basis.
  2. Use the actual policy wording or internal data definition for every limit, deductible, premium, loss, and recovery input.
  3. Compare multiple plausible scenarios and treat probabilistic outputs as model results rather than forecasts or coverage determinations.

Calculation method

Calculation method

Each expense applies remaining deductible, then coinsurance, while member cost is capped by the entered out-of-pocket maximum.

Deterministic currency and ratio calculations use exact fixed-decimal arithmetic. Simulated or distribution-based tools identify their approximation and reproducibility conventions.

Worked example

Worked example

Several eligible expenses can be processed in order to show deductible and out-of-pocket accumulation.

Each expense applies remaining deductible, then coinsurance, while member cost is capped by the entered out-of-pocket maximum.

Supported inputs

Precision and limits

Insurance and risk scope

This is a country-neutral planning or statistical scenario using visitor-entered policy terms, losses, probabilities, and financial assumptions. It does not quote insurance, determine eligibility, interpret legal coverage, set reserves, or recommend a product.

Policy wording controls

Actual deductibles, exclusions, valuation clauses, waiting periods, sublimits, aggregates, reinsurance terms, and legal coverage depend on the contract and jurisdiction. The calculator cannot interpret or bind coverage.

Model and data consistency

Keep gross versus net, written versus earned, paid versus incurred, exposure periods, probability horizons, and currency bases consistent. Historical averages and probability models do not guarantee future outcomes.

No quote or professional determination

Results do not quote a premium, approve a claim, establish an actuarial reserve, determine regulatory capital, recommend self-insurance, or replace an insurer, broker, actuary, accountant, risk professional, or legal adviser.

Precision and privacy

Plain decimals accept up to 30 digits and 12 decimal places. Calculations remain in this browser and raw entered values are not submitted to 365CALCS.COM.
