How to use this tool

  1. Enter price, balance, bundle, bonus, cost.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "price": 1350,
  "balance": 200,
  "bundle": 500,
  "bonus": 50,
  "cost": 4
}

Accuracy and scope

All purchased bundles have the same price and repeatable bonus. No first-purchase bonus, regional pricing, taxes, refunds or mixed-bundle optimization.
