Before you invest a single euro

Before you invest, you need three things: no expensive debt, a cushion for emergencies, and money you won't need for several years. Missing any one of them means investing isn't your next step yet.

Almost every site about investing starts with the question of which stock to buy. That's the wrong first question. The right one is: is my everyday life stable enough that I can leave money untouched for years?

Think of a house. Nobody paints the walls before the roof stops leaking. Investing is the paint. An emergency fund, being debt-free, and a clear view of your own spending are the roof.

Three questions decide whether you should keep reading or sort something else out first. First: do I have debt costing more than roughly five percent interest a year? Second: do I have a cushion in case the washing machine and the car break down in the same month? Third: do I know what's left over at the end of the month?

Answer all three honestly with yes, and you can start. Answer no, and you lose nothing, you gain time. The markets aren't going anywhere. They've been around for over a hundred years, and they'll still be there in two years.

The order that matters. Nobody paints the walls before the roof stops leaking.Pay off expensive debtBuild an emergency fundInsure the essentialsInvestzerotoinvest.com

Summary

  • Paying down debt beats investing when the interest rate is high.
  • Without an emergency fund, you'll be forced to sell at the worst possible moment.
  • How much you save matters more than what you buy.

Did you get it?

Why is paying off an overdraft often better than investing?

Because the interest you save is a guaranteed, tax-free return, while an investment only offers an uncertain one.

What is the emergency fund technically there for?

So that unexpected expenses never force you to sell your investments at a bad time.

Which shapes your result more over many years: the savings rate or which securities you pick?

As a rule, the savings rate.
