How this estimate works

Formula usedEstimated payout = (eligible amount after limits − deductible) × (1 − co-pay percentage)

Policies may apply limits and cost sharing in a different order. Use the claim calculation method in the policy wording; this model is for understanding the effect of each component.

Check your inputs & compare scenarios

Replace the examples with your current figures. Keep the currency and time period consistent with each field. Save one scenario, then change an amount or rate to compare the effect. Reopened scenarios calculate with current rules; your original result stays in history.

Questions & answers

Frequently asked questions

A deductible is the specified amount applied before benefits become payable. Co-payment is the specified share of the admissible claim that the insured must bear.

Which policy documents should I check? +

Use the policy schedule, Customer Information Sheet, benefit illustration and insurer quotation. Enter the exact cover, premium, factor, sub-limit or charge shown for your policy.

Does this replace an insurer quotation or professional advice? +

No. It is a planning estimate. Underwriting, medical history, exclusions, waiting periods, tax treatment and product-specific terms can change the final premium, benefit or claim.
