Why Should You Use the DTC Creative Calculator?

This is the exact framework Prospa uses to consistently produce high-performing creative at scale for
e-commerce brands. It shows you what content to create, why it works, and how to turn it into ads that actually convert.

Know exactly how many creatives your spend demands

Most brands underproduce creative for the budget they're running.

Plug in your monthly ad spend and the calculator instantly tells you the minimum creative volume you need to keep CPMs healthy, fight fatigue, and feed the algorithm.

No more guessing whether 20 assets a month is enough, you'll know.

Benchmark your testing velocity against scaling brands

The difference between brands that plateau and brands that scale isn't budget, it's how fast they test.

The calculator compares your current testing cadence to the brands we scale past £1M/month in ad spend, so you can see exactly where you're falling behind on iteration speed.

Build a defensible creative budget for your finance team

Stop pitching creative spend as a gut feel.

The calculator gives you the numbers to walk into a board meeting and justify exactly why you need X creatives per month at Y production cost, tied directly to revenue and ROAS targets.

Move creative from "cost centre" to "growth lever" in one conversation.

Spot the bottleneck in your current creative pipeline

The calculator highlights where your pipeline is leaking, whether it's not enough hooks per concept, too few formats in rotation, or a testing cadence that can't keep up with spend.

Same diagnostic logic we run on every audit. Fix the right thing, not the loudest thing.

Turn every ad into a readable experiment

Most brands learn nothing from their tests because too many variables move at once.

The hook changes, the format changes, the visual changes, so when an ad wins or loses, there's nothing repeatable to take away.

This system enforces one variable per iteration, with the Theme and Audience held constant, so every result becomes a decision you can act on.
