Extract guaranteed promo value with zero downside.

How to use these tools
Start with the calculators to size a hedge, then use the promo planner to map your guaranteed promo value. When you need context or assumptions, jump into the Strategy Guide.
Each tool is built to show a conservative, minimum-value view of what you can extract. The goal is simple: eliminate downside, avoid guesswork, and treat promos like constrained math problems.
If you’re new here, I highly recommend reading through the whole site so you understand the free-money opportunity available and the assumptions behind the numbers.
