Fees

Learn how PUNCH.WIN calculates taker fees, which actions are fee-exempt, and how 50% of fees are redistributed to makers.

Fees are charged only to Takers. Makers pay 0% fees + receive Rebate. Maker Rebate Fee Rate varies by market expiry. See FeeRate by Market below.

Fee Formula

fee = feeRate × Shares × p × (1 - p)

Variable	Description	Value
feeRate	Fee rate	Varies by market (see below)
Shares	Number of shares	—
p	Price	$0.001 – $0.999

Fees are highest at $0.500 (50/50 odds) and decrease as the price moves toward $0.001 or $0.999 (heavily skewed odds).

Fee Calculation Examples

All examples use 100 Shares @ $0.650, where p × (1-p) = 0.2275.

1-Min Market

100 Shares @ $0.650, FeeRate 0.500

fee   = 0.500 × 100 × 0.650 × 0.350 = $11.375
total = 100 × 0.650 = $65.000
Total cost = 65.000 + 11.375 = $76.375

3-Min Market

100 Shares @ $0.650, FeeRate 0.300

fee   = 0.300 × 100 × 0.650 × 0.350 = $6.825
total = 100 × 0.650 = $65.000
Total cost = 65.000 + 6.825 = $71.825

5-Min / Sports Market

100 Shares @ $0.650, FeeRate 0.100

fee   = 0.100 × 100 × 0.650 × 0.350 = $2.275
total = 100 × 0.650 = $65.000
Total cost = 65.000 + 2.275 = $67.275

1-Hour / Daily Market

100 Shares @ $0.650, FeeRate 0.050

fee   = 0.050 × 100 × 0.650 × 0.350 = $1.138
total = 100 × 0.650 = $65.000
Total cost = 65.000 + 1.138 = $66.138

Other Market

100 Shares @ $0.650, FeeRate 0.025

fee   = 0.025 × 100 × 0.650 × 0.350 = $0.569
total = 100 × 0.650 = $65.000
Total cost = 65.000 + 0.569 = $65.569
