At a glance
- Lay statements, agreements, and usage side by side.
- Compute the effective rate as your comparable number.
- Read contracts for renewals, escalators, and surcharges.
You do not need permission to start auditing your own costs. The Profit Alchemist lays out a structured approach: gather recent statements, calculate effective rates, and read contracts for the clauses where overpayment hides. The work is methodical, not mysterious.

Gather the raw material
A useful audit starts with recent statements, the underlying agreements, and basic usage figures.
These three inputs let you see what you are actually paying, what you agreed to pay, and how much you use. Most overpayment becomes visible the moment those three are laid side by side.
Calculate the effective rate
The core of the audit is computing the effective rate: the true cost after every surcharge and fee.
That single number turns a confusing invoice into something comparable. It is what you benchmark against the market, and it is where errors and drift first show themselves.
Read the contract for traps
The last step is reading the agreements for auto-renewal windows, escalators, and surcharge language.
These clauses are where future overpayment is written in advance. Marking the notice dates and flagging the escalators gives you the leverage to act before the next renewal rather than after it.
