Add-On Revenue Calculator
Add-ons let backers purchase additional items beyond their main reward tier. They can significantly boost your total campaign revenue, sometimes by 15-30%. This calculator helps you plan your add-on strategy and estimate the additional revenue they can generate.
How Add-Ons Work
On platforms like Kickstarter and Indiegogo, backers can increase their pledge amount to include add-on items. You manage this through backer surveys after the campaign ends. Some platforms (like BackerKit) specialize in post-campaign add-on management.

Add-On Strategy Guide
Pricing Your Add-Ons
- Physical items: Price at 2.5 to 3 times your production cost to cover shipping, packaging, and unexpected expenses
- Digital items: Price at $5 to $15 depending on perceived value. Your cost is essentially zero, so every sale is profit
- Experiences: Price based on your time value and exclusivity, not production cost
When to Introduce Add-Ons
- During campaign: Mention add-ons in your campaign description so backers know they can get extras
- Mid-campaign update: Announce new add-on items as a momentum booster during the mid-campaign slump
- Post-campaign survey: The backer survey is your biggest add-on opportunity. Many backers will add items when confirming their reward details
Platform-Specific Add-On Management
| Platform | Add-On Method | Notes |
|---|---|---|
| Kickstarter | Backers increase pledge amount, specify add-ons in survey | Use BackerKit or PledgeManager for post-campaign add-on management |
| Indiegogo | Add-on perks can be created directly on the platform | InDemand mode allows continued sales after campaign ends |
| GoFundMe | Not a traditional add-on model | Better suited for donation-based campaigns |
Fulfillment Tips for Add-Ons
- Track add-on orders separately from main rewards in a spreadsheet
- Order add-on inventory based on actual survey responses, not estimates
- Ship add-ons with the main reward when possible to save on postage
- Set a deadline for add-on orders so you can place a single production order
