Re: The 40% Rule

Your annual revenue growth rate + your operating margin should equal 40%

My immediate reaction: So I guess I need to cut Tarsnap's prices and slow its growth rate?

On further thought, I suspect "should equal" should be "should equal or exceed".

I wondered that as well as I'm in the same situation, but then I wondered if it works as a target if it means we should be spending more on staff and reinvestment to grow even more? But that'd mean the %age gets even higher so.. maybe not ;-)

I also don't really understand why having a higher margin is useful in a declining business. It's either a lost cause or one should be reinvesting in reversing the growth problem, no..?

Not necessarily. Might just be a shrinking target audience, but if you can keep a good margin there's no reason not to keep serving a non-growth market.

They key is this applies for mature companies. He quotes $50mm or higher in revenue. It breaks down earlier.

I disagree, in personal finances you aren't afforded the same kind of burn rates because there isn't an investor model for individuals. If my salary has increased 100% YoY for the last 3 years, I would be in a troubling amount of debt. This applies in reverse as well, if you take a salary cut you likely aren't going to be able to save more money as a result. For personal finances I think its better to tease out a bas…

This is exactly what people do when they go to school: they take on huge amounts of debt in order to make their income grow by >100% YoY for a few years. Very few incoming college students know enough about finance or exactly what different choices will payout to make smart trade-offs in this area, but this reasoning is pretty common with MBA and Law School students. Occasionally it even works; I've known a few young…

On writing my response I realized school was probably the one time where this sort of strategy would be appropriate for an individual. At the same time, school is a much higher risk proposition (in many cases) and involves much more time and debt than the 40% guideline accounts for.

You also have to keep in mind that most people who finish law school don't get big law jobs that allow them to pay off loans quickly. The same holds true for MBAs and most PhDs. About the only advanced degree that has some level of income guarantee (for now) is a MD. So while school can fit the 40% rule, it rarely does.

Banks invest in individuals by offering loans.

Loan = Investment?

Typically any type of debt is considered an investment by the creditor.

Bonds and equity are also considered investments, but the latter is corporate ownership, not debt (which you may be confused about).

It means Tarsnap isn't spending enough on growth.

Or I think he means you should be spending more on R&D and marketing.

Not sure why this won't still work in theory. 100% YoY increase: Salary Year 1: $100 - you are allowed to go $60 into debt Salary Year 2: $200 - you are allowed a further $120 Salary Year 3: $400 - you are allowed a further $240 Salary Year 4: $800 - your total debts are still around half a year's salary, which is only modestly troubling - banks would most likely be happy to service your debt at a competitive rate. I…

This is a good analogy if the debt is invested in your personal financial growth somehow, for instance through education or perhaps actual investments, but a terrible analogy for the kind of deficit-spending most people do, like on cars and high living expenses.

It means there is more room for growth that you are missing. So you should spend more, but not much so that you keep at the 40% rule.
