How we calculate

The maths, in plain sight.

One month of challenge sales, start to finish. The rewards those challenges lead to are counted too, even when they are paid in a later month.

What it leaves out

  • Payment and platform fees
  • Trading platform and data costs
  • Staff, tools and affiliate commissions
  • Taxes

So the result is what is left to pay for those, not profit.

  1. 1
    Challenges sold from ads

    ad spend ÷ cost per challenge sold

    From clicks: cost per challenge sold = cost per click ÷ share of visitors who buy.

    Your numbers: $24,000 ÷ $80 = 300

  2. 2
    All challenges sold

    challenges from ads × (1 + repeat purchases)

    Your numbers: 300 × (1 + 0%) = 300

  3. 3
    Revenue after refunds

    all challenges × price × (1 − refund rate)

    Your numbers: 300 × $180 × (1 − 6%) = $50,760

  4. 4
    Rewards paid

    challenges kept after refunds × pass rate × passers rewarded × average reward

    Your numbers: 282 × 10% × 45% × $900 = $11,421

  5. 5
    Left after ads and rewards

    revenue − ad spend − rewards paid

    Your numbers: $50,760 − $24,000 − $11,421 = $15,339

  6. 6
    Break-even cost per challenge sold

    (1 + repeat) × (1 − refund rate) × (price − pass rate × passers rewarded × average reward)

    Your numbers: (1 + 0%) × (1 − 6%) × ($180 − 10% × 45% × $900) = $131
