What is Profit First about?
Michalowicz flips the usual accounting formula. Instead of profit being what is left after expenses, you take profit first and run the business on what remains, using a simple system of separate bank accounts.
Profit First summary
Michalowicz starts from a problem most business owners recognise: money comes in, money goes out, and somehow there is never any profit left. The usual formula, sales minus expenses equals profit, leaves profit as an afterthought that never arrives.
His fix is to reverse it: sales minus profit equals expenses. You take a set percentage as profit first, along with allocations for your own pay and tax, and force the business to run on what is left. The mechanism is deliberately simple, several separate bank accounts, so that the money for profit, tax and pay is physically moved out of reach before you can spend it on running costs.
He builds on the idea that most people manage money by what they see in the main account, so by keeping temptation out of sight, the system works with human nature rather than against it. It is behavioural accounting for people who are not accountants, and its simplicity is the point.
Published in 2014 and revised since, it became a popular system among small-business owners and freelancers. It is aimed at people who make money but struggle to hold on to any of it.
Key ideas and takeaways
- Profit first. Reserve profit before expenses, not after.
- Separate accounts. Move profit, tax and pay out of the main account so you cannot spend them.
- Work with human nature. People spend what they see, so hide what should not be spent.
- Small percentages, regularly. Start with modest allocations and increase them over time.
My honest take
This is the money book I recommend to freelancers who earn decent money but never seem to keep any. The clever part is not the accounting, it is the behaviour: by moving profit, tax and your pay into separate accounts the moment money lands, you stop the business quietly eating everything.
So many self-employed people run everything from one account, see a healthy balance and spend it, then panic at tax time. Michalowicz's system is simple enough to actually stick to, which matters far more than being clever. Twenty years in, the people I have seen stay solvent are the ones with a system like this, whatever they call it.
It is repetitive and a little evangelical, and if you already run tight books you may find it basic. But for the many people who avoid looking at their finances at all, its simplicity is exactly why it works where spreadsheets have failed.
Where it falls short
- Repetitive and a touch evangelical about the system.
- Aimed at people with no system, so experienced owners find it simplistic.
How it compares
The Psychology of Money explains why we behave badly with money; Profit First gives you a mechanical system that works around that behaviour. Read Housel for the why and Michalowicz for the how.
Who should read it (and who should skip it)
Freelancers and owners who earn well but never keep a profit. Skip it if your financial systems are already solid.
How to actually use it if you are self-employed
- Open separate accounts for profit, tax and your own pay.
- Move a small percentage into each the moment money comes in.
- Run the business on what is left, and raise the percentages over time.
- Take profit first, run on what is left.
- Use separate accounts to hide money from yourself.
- Keep it simple so you actually stick to it.

Frequently asked questions
What is the Profit First formula?
Sales minus profit equals expenses. You take profit first and run the business on what remains.

Is it for freelancers or bigger businesses?
Both, but it is especially useful for freelancers and small owners with no financial system yet.
Is it complicated to set up?
No. The whole point is simplicity, a handful of accounts and regular transfers.
Will my accountant approve?
Many do, as it enforces tax and profit discipline. Check the specifics for UK tax with yours.
