Set the Loss Limit Before the Test, Not While You're Watching It Bleed

A product isn’t generating profit, but it isn’t clearly dead either, and the testing continues with no clear sense of when it should really stop, spending more with each passing day and no fixed criterion behind the decision. The root of that indecision is simple: nobody defined, before starting, how far it was worth going.

Setting an accumulated loss limit before running a single campaign, some fixed value relative to the initial test investment, turns that open-ended question into a documented line. While the product sits at breakeven, neither profitable nor losing, it usually deserves another round of creative iteration before getting discarded, since plenty of products only take off after several angle attempts. Once the defined limit is hit, the decision to stop has effectively already been made, which strips out the emotional weight of giving up: it isn’t a personal failure, it’s just the agreed-upon criterion doing its job.

The one thing that undoes this entire approach is moving the limit mid-test, pushing it forward to justify one more attempt as the loss grows. That defeats the purpose of having set a limit at all. Keeping a simple record of every ongoing test alongside its defined limit makes it easy to see, at a glance, which products still have room to run and which should already be closed. A clear limit set in advance isn’t pessimism. It’s what makes it possible to test with confidence, knowing exactly how far the operation is willing to go before changing direction.
