How to calculate insurer's and patient's share of medical procedure costs?

Here's an example: We are looking for the insurer's and patient's portions of $2500 with 80% coverage. Insurer pays = (80 / 100) × $2500 = 0.8 × $2500 = $2000. Patient pays = $2500 - $2000 = $500.

Calculation type: Calculating a percentage of a number (insurer's share) and the remaining amount (your share).
How to use the calculator:
Step 1 (Insurer's share): Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter 80 [X] and $2500 [Y]. It will calculate 80% of $2500.
Step 2 (Your share): Subtract the amount covered by insurance (from Step 1) from the total cost.
The formula:
We want to find the insurer's share (80% of $2500) and your share.
Insurer's share = 80% of $2500
Insurer's share = (80 / 100) × $2500 = 0.8 × $2500 = $2000
Your share = Total cost - Insurer's share
Your share = $2500 - $2000 = $500
