Before you set your goal
See how the proposed platform fee affects your target. Add a processing estimate when you have one, then allow for production, delivery and unexpected costs.
Estimates are for planning. Display currencies do not confirm payment availability or convert money.
Proposed for successful funding.
Payment processing is separate.
Currency changes the display only. No exchange conversion.
Use the total cost quoted by your payment provider. We do not assume a processing rate.
A planning estimate, not a payment quote or payout. Final fee treatment, availability and payment terms must be confirmed before launch.
The details, explained
The 3% rate is the proposed standard marketplace model. It is not yet a live billing commitment. Final agreements must confirm availability, who pays, how the fee is collected and what happens if a payment is refunded. The estimator helps you plan; it does not initiate a payment.
Processing is separate from the proposed platform fee. Its cost depends on the provider, country, currency and payment method. If you already have a provider estimate, add the total to the calculator to see the combined estimate. An unknown processing cost is not treated as zero.
The proposed standard marketplace model has no monthly creator subscription. Foundation and network programmes may have their own scoped agreement. You can start a project draft without purchasing a subscription.
The proposed model is a success fee for a successfully funded project, with no platform success fee if the funding target is not reached. The final payment terms must define the funding conditions, collection timing, refunds and fee treatment before live contributions are accepted.
BackThisBuild is designed for discovery across regions. The estimator supports several display currencies, without exchanging money or confirming launch eligibility. Creator and payment availability must be confirmed for your country before launching.
No. Project plans, updates and evidence help people assess a project, but do not guarantee delivery or remove risk. Creators need to explain delivery expectations, risks and applicable refund terms before anyone contributes.
