Promo code redemptions are a floor, not the full picture of what a creator drove. Enter code orders, reach and cost per creator to get conversion per creator and an estimate of the halo sales codes miss.
The numbers below are illustrative starting assumptions, not benchmarks. Replace every one. The result is saved in the URL.
Drives the halo estimate: estimated orders = code orders / this share. 50% is a placeholder, not a measured figure. 100% means no halo.

Estimated orders including halo
Make the codes with the bulk discount code generator, and see what each gift cost in the gifting ROI calculator.
Enter reach, link clicks (0 if unknown), code orders from your Shopify discount data, and what the gift cost you.
| Creator | Reach (views) | Link clicks | Code orders | Cost of gift | Remove |
|---|---|---|---|---|---|
| Creator | Code orders | Orders per 1,000 reach | Click to order | Est. orders (halo) | Code revenue | Revenue per 1 spent: code | Revenue per 1 spent: est. |
|---|---|---|---|---|---|---|---|
| Creator A | 12 | 0.30 | 1.3% | 24 | $720.00 | 16.0x | 32.0x |
| Creator B | 6 | 0.40 | 2.0% | 12 | $360.00 | 8.0x | 16.0x |
| Creator C | 1 | 0.13 | n/a | 2 | $60.00 | 1.3x | 2.7x |
| Total | 19 | 0.30 | n/a | 38 | $1,140.00 | 8.4x | 16.9x |
Revenue is orders x average order value, a simplification: it ignores returns, shipping and margin. "Revenue per 1 spent" divides revenue by what the gift cost you.
One branded link per campaign creates the $0 draft order in Shopify, tagged by campaign, so you know exactly what each creator cost. This calculator stays free and ungated.
Install Seed on ShopifyA code only records a sale when a buyer remembers it, has it handy and types it at checkout. Several things break that chain:
Codes can also over-count when a creator's code leaks to a coupon site and strangers use it. Tag the links you hand creators with the influencer UTM builder so you have a second signal next to the code, and ask buyers "How did you hear about us?" after purchase to sanity-check your code-usage share. Generate one code per creator with the bulk discount code generator, and log results in the influencer tracking spreadsheet.
| Signal | Catches | Misses |
|---|---|---|
| Promo code | Buyers who type the code | Buyers who do not, and leaked-code users are wrongly included |
| Tagged link (UTM) | Same-browser clicks within your analytics window | Cross-device and later visits |
| Post-purchase survey | Self-reported influence, including halo | Non-respondents and fuzzy memory |
| Branded search or direct lift | Aggregate effect around a post | Cannot be tied to one order or creator |
Exact for the orders that use the code, but only a floor for a creator's total impact. Buyers who click a link and never type the code, or buy later after searching your brand, do not show up. Codes can also overcount when they leak to coupon sites. Treat the count as a minimum.
Halo sales are orders a creator influenced that no code or link captured, such as someone who saw a post and later searched your brand name and bought. You cannot count them directly, which is why this calculator estimates them from an assumption you set and can change.
It is your estimate of what fraction of a creator's orders come through with the code. There is no standard figure, so the 50% default is only a placeholder. Better inputs come from a post-purchase survey asking how buyers found you, compared with the code orders you recorded.
Report code-attributed revenue as the confirmed number and the halo as a labelled estimate with the assumption stated beside it. Mixing them into one figure without saying so invites distrust, because the halo depends entirely on the code-usage share you chose.
Orders per 1,000 reach = code orders / reach x 1,000. Click to order = code orders / link clicks (blank when clicks is 0). Estimated orders = code orders / (code-usage share). Estimated halo = estimated orders - code orders. Revenue = orders x average order value. The code-usage share is your own assumption and the only source of the halo number: this tool has no measured halo data and cites no industry benchmark.
