# What GEO really earns your agency > Estimate what GEO earns your agency: the right Layers plan, monthly cost, margin, return on investment and the production hours you get back each month. Canonical URL : https://trylayers.ai/en/roi-calculator/ Language : en Enter three numbers. The calculator gives you the plan you need, its cost, and what your GEO audits bring in once your billable time is taken out. ## Your settings - **Clients tracked in GEO** : The clients you produce a GEO audit for every month. - **Audit selling price** : What you bill your client for the audit, per month. - **Your day rate** : The daily rate of the consultant who produces the audit. ## Example, with the calculator's default values - Clients tracked in GEO : 12 - Audit selling price : €1,200 - Your day rate : €650 - Your return on investment : ×20.0. Every €1 invested brings back €20.0. - Net profit : €13,680 out of €14,400 billed - Total cost : €720 (€349 subscription + €371 of time) - Margin : 95.0% of GEO revenue - The plan you need : Growth, €349 excl. VAT / month. Clients covered : 16. Credits included : 8,000. Cost per client : €29.08 - The time you get back : 44 h saved every month, worth €4,086 of billable time ## How it is calculated - The plan is picked on the basis of 500 credits per client per month: Essential: 3,000 credits (6 clients), Growth: 8,000 credits (16 clients), Scale: 20,000 credits (40 clients). Beyond that, volume falls under a Custom plan, whose displayed price is an estimate at the Scale plan credit rate. - Time is valued at your day rate brought down to an hour, over a 7-hour day. An audit takes 4 h by hand, against 20 min with Layers. - Total cost = Layers subscription + time spent. Profit = audit revenue − total cost. Return on investment is revenue divided by total cost. - Monthly amounts, excluding VAT. Prospecting and presenting to the client are not counted: they are the same with or without Layers.
