Insurance Estimate (Coverage After Deductible)

Excel Formulas › Dental Practice

All versionsMAX

A dental plan pays a coverage percentage of the allowed fee, after the deductible. The estimate: apply the deductible first, then the coverage percent — bounded by the annual maximum.


Quick formula: estimated insurance payment:
=(allowed_fee - deductible) * coverage_pct
Subtract the deductible from the allowed fee, then apply the coverage percentage. Cap at the remaining annual max.

The formula

The formula:

=(allowed_fee - deductible) * coverage_pct // (allowed − deductible) × coverage %

How it works

How it works:

  1. Apply the deductible to the allowed fee first (once per benefit period).
  2. Multiply the remainder by the coverage percentage for the procedure category.
  3. Cap the payment at the remaining annual maximum with MIN.
  4. Preventive is often 100%, basic 80%, major 50% — use the right category.

Illustrative estimate only — not a guarantee of benefits or clinical/financial advice. Actual coverage depends on the patient’s plan, frequency limits, downgrades, and the carrier’s determination. Always verify benefits and read the plan.

Variations

Capped at annual max

Remaining benefit:

=MIN((allowed-deductible)*coverage_pct, remaining_max)

Deductible not yet met

Apply only what is left:

=(allowed - MIN(deductible_remaining, allowed)) * coverage_pct

By category

Right percent:

=(allowed-deductible) * VLOOKUP(category, table, 2, FALSE)

Pitfalls & errors

Deductible first. Subtract the deductible before applying coverage %.

Allowed fee. Coverage is on the plan-allowed amount, not your full fee.

Not a guarantee. Verify benefits — estimates can differ from payment.

Frequently asked questions

How do I estimate a dental insurance payment in Excel?
Apply the deductible then the coverage percent: =(allowed_fee - deductible) * coverage_pct. A $200 fee, $50 deductible, 80% pays $120.
How do I cap it at the annual maximum?
Use MIN against the remaining benefit: =MIN((allowed-deductible)*coverage_pct, remaining_max).
Why use the allowed fee, not my fee?
Plans pay a percentage of their allowed amount; the difference may be a write-off or patient responsibility depending on participation.
