Why do Kickstarter pledges fail after campaign success?

After campaign succeeds, Kickstarter charges cards over 2 weeks. 2% to 5% fail due to expired cards, insufficient funds, fraud checks, especially international. On $15k with 300 pledges, 5% fail = $750 never collected, collected $14250. You pay fees only on collected $14250, not pledged total. If 10% fail at $50k, you lose $5000 before fees. To reduce, message backers pre-end to update cards, offer PayPal backup, and keep survey quick.

How to estimate refund and chargeback costs?

Physical rewards typical 2% refunds for damaged, lost, wrong size. Chargebacks 0.5% for fraud or dissatisfaction, each costs pledge value plus $15 Stripe fee. Example: $14250 collected, 2% refund $285 must return, 0.5% chargeback = 1.5 pledges average $47.50 each ≈ $71.25 plus $22.50 fee = $93.75 total chargeback cost. Under 1% refund rate good; over 5% indicates product issue. This calculator shows fulfilled pledges drop to 277 when 5%+2%+0.5% losses.

Do I still pay Kickstarter fees on refunded pledges?

Fees on failed pledges that never collect are not charged. For refunds after collection, Kickstarter's platform fee may be refundable if within window? In practice platform 5% often non-refundable after funds disbursed, processing fees partially refunded depending on timing. This calculator conservatively assumes you already paid fees on collected then refund pledge value separately, not double counting fee return, so net realistic slightly pessimistic. If Kickstarter refunds its fee portion, add that to net manually up to 5% of refunds.

How to improve collection rate?

Collection rate = net collected ÷ pledged. 95% typical. Below 92% high failure. To improve: set $5 minimum to avoid test card $1 fails, communicate 2 days before end 'campaign ending, update card', allow PayPal, chase failed with Kickstarter's failed pledge recovery tool — you have 7 days to retry failed cards. Each 1% improvement on $15k is $150. Model 5% vs 2% failed to see $450 difference before fees.

Should I include production for refunded backers?

No. Only fulfilled pledges need production. If backer refunds before production, you save $15 prod + $8 fulfill = $23. This calculator multiplies production only by fulfilled count: fulfilled = total × (1 - failed - refund - chargeback). So refunds reduce production cost automatically. If you already produced before refund, you incur waste — enter extra fixed costs in profit calculator to cover waste 2% of production total.

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.

Interpretation

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

$15k pledged, 5% failed $750 lost, collected $14250. Fees on $14250: platform $712.50 + processing $427.50 + fixed 285×$0.20=$57 total $1197. Refunds 2% $285, chargeback value $71.25 + 1.5×$15=$22.50 fee total $93.75. Fulfilled 277.5 pledges ×$23=$6382.5 production+fulfillment. Net actual $14250-$1197-$285-$93.75-$6382.50=$6291.75. Collection 95%, net margin ~44.15% of collected.
