How the Client Profitability Calculator works

Formula
Client profit = Revenue − Cost to serve · Margin % = Profit ÷ Revenue × 100

Your biggest client is not always your most profitable. A high-revenue account that consumes endless hours can earn you less per hour than a smaller, easier one — and you’d never know without measuring the cost to serve each client against the revenue they bring.

Add the hours spent to see profit per hour, the clearest signal of all. Use it to reprice or reset scope on the accounts that drain you, and to do more of the work that actually pays — then bill it cleanly with Aviy.

Frequently asked questions

Why measure client profitability?

Because your biggest client isn’t always your most profitable. A high-revenue client that eats endless hours can earn you less per hour than a smaller, easier one.

What is “cost to serve”?

Everything a client costs you: your time at cost, subcontractors, software, and expenses specific to them. Compare it against the revenue they bring.

What do I do with the result?

Raise prices or reset scope on low-margin clients, and do more work with your most profitable ones. Profit per hour is the clearest signal.
