How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Calculate platform fee as totalRaised × platform%
- 2Calculate processing percent and fixed portions
- 3Sum fees = platform + processing% + fixed
- 4Net after fees = raised - fees
- 5Production total = pledges × productionCostPerUnit
- 6Fulfillment total = pledges × fulfillmentCostPerUnit
- 7Total all costs = fees + production + fulfillment + fixed
- 8Net profit = raised - totalAllCosts
- 9Margin = netProfit ÷ raised ×100
- 10Tax = max(0, netProfit) × tax%
- 11After-tax = netProfit - tax
Formulas
- Platform = raised × platform%
- Processing = raised × proc% + pledges×fixed
- NetAfterFees = raised - totalFees
- Production = pledges × prodPerUnit
- Fulfillment = pledges × fulfillPerUnit
- NetProfit = netAfterFees - production - fulfillment - fixedCosts
- Margin = netProfit ÷ raised ×100
- AfterTax = netProfit - tax
Important assumptions
- Platform fee = totalRaised × platformFeePercent
- Processing = totalRaised × processingPercent + pledges × processingFixed
- Net after fees = totalRaised - total fees
- Production total = numberOfPledges × productionCostPerUnit — assumes one reward per pledge
- Fulfillment total = pledges × fulfillmentCostPerUnit
- Net profit = netAfterFees - production - fulfillment - fixedCosts
- Tax only when profit >0, calculated as netProfit × taxesPercent
Worked example
$15k raised, 300 pledges, $15 prod, $8 fulfillment, $2000 fixed
Total $15k, 300 pledges, 5% + 3% + $0.20 fees, production $15, fulfillment $8, fixed $2000, tax 25%
