Kickstarter Return and Refund Calculator
Kickstarter campaigns show total pledged, but not all pledges collect due to expired cards — 2% to 5% typically fail after funding. Then some backers request refunds and a few chargebacks happen with extra $15 fees. Enter total raised, pledge count, failed pledge rate, refund rate, chargeback rate and fee, plus per-unit production and fulfillment to see failed pledges lost, net collected, fees on collected, refunds, chargeback costs, fulfilled pledge costs, net actual profit, collection rate, and profit margin on collected.

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 failed amount = raised × failedRate
- 2Net collected = raised - failed
- 3Fees on collected = collected × platform% + collected × processing% + collectedPledgeCount × fixed
- 4Collected pledge count = pledges × (1 - failedRate)
- 5Refunds = collected × refundRate
- 6Chargebacks pledge value = collected × chargebackRate
- 7Chargeback count = pledges × chargebackRate
- 8Chargeback fees = count × fee
- 9Fulfilled = pledges × (1 - failed - refund - chargeback)
- 10Production = fulfilled × prodCost, fulfillment = fulfilled × fulfillCost
- 11Net actual = collected - fees - refunds - chargebackValue - chargebackFees - production - fulfillment
Formulas
- Failed = raised × failedRate
- Collected = raised - failed
- FeesOnCollected = collected×platform% + collected×proc% + collectedPledges×fixed
- Refunds = collected × refundRate
- ChargebackValue = collected × chargebackRate
- ChargebackCount = pledges × chargebackRate
- Fulfilled = pledges × (1 - failed% - refund% - chargeback%)
- NetActual = collected - fees - refunds - chargebacks - prod - fulfill
Important assumptions
- Failed pledges = totalRaised × failedPledgeRate, never collected
- Net collected = totalRaised - failed
- Fees calculated on net collected, not pledged total, using same formula: platform% + processing% + fixed per collected pledge
- Refunds = netCollected × refundRate
- Chargeback value = netCollected × chargebackRate, fee total = estimated chargeback count × avg fee, where chargeback count = totalPledges × chargebackRate
- Fulfilled pledges = totalPledges × (1 - failedRate - refundRate - chargebackRate)
- Production/fulfillment only for fulfilled pledges
Worked example
$15k pledged, 5% failed, 2% refunds, 0.5% chargebacks
Total $15k, 300 pledges, 5% failed, 2% refunds, 0.5% chargebacks $15 fee, production $15, fulfillment $8
