Marketing Efficiency Calculators
Every other category here judges one channel at a time. This one judges the whole operation — which is the only view that survives when attribution stops working.
Marketing Efficiency Ratio Calculator
Work out your marketing efficiency ratio — blended ROAS by its other name — and measure the return of your entire budget across every channel at once.
Marketing Budget Allocation Calculator
Divide your budget in proportion to channel efficiency (ROAS), for two to eight channels — a fast orientation for the next allocation decision, not a forecast.
Channel Mix Calculator
See how revenue is distributed across your channels — and whether a dangerous dependency on one single platform is forming while you are not looking.
Simulate every efficiency metric at once
The Marketing Cockpit shows immediately how MER, budget split and channel mix interact.
Open the Marketing CockpitSteering marketing as a whole, not channel by channel
The marketing efficiency ratio sets total revenue against total marketing spend across every channel, and its usefulness is inverse to how well your tracking works: precisely when platform ROAS figures are distorted by attribution gaps, the MER stays reliable — because it has nothing to attribute. It is the number to steer by, not to optimise directly. The budget allocation calculator then splits a fixed budget across channels by their efficiency, and the channel mix calculator compares where revenue actually comes from, which is how concentration risk becomes visible before it becomes a problem. Read together: the MER tells you whether the whole is working, the other two tell you where to move the money.
