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 a few years. If one of them is missing, investing isn't your next step yet.

Learning objective: After this lesson you can use three questions to decide for yourself whether investing fits you right now.

Almost every site about investing starts with the question of which stock to buy. A different question matters much more: is your everyday life stable enough that you can leave money untouched for a few years?

Sophie's Starting Point

Take Sophie. She has €3,000 in her account and finally wants to start with an ETF. At the same time her overdraft stands at minus €1,200, and her car is twelve years old. If she buys now and the clutch goes in autumn, she'll have to sell, maybe just when prices are low.

Three Questions Before You Start

Three questions help before you get going:

  • Do I have debt that costs more than about five percent interest a year?
  • Do I have an emergency fund in case the washing machine and the car break in the same month?
  • Do I know how much is really left at the end of the month?

If you can honestly answer yes to all three, you can start. If not, you lose nothing. You use the time to lay the groundwork. The stock market has been around for over a hundred years, and it will 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

The order is: pay off expensive debt, build an emergency fund, insure the essentials, invest.

Summary

  • With high interest rates, paying off debt beats investing.
  • Without an emergency fund you may have to sell at the worst moment.
  • How much you save usually 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 certain and tax free, while an investment only promises an uncertain return.

Why do you need an emergency fund before investing?

So an unexpected expense doesn't force you to sell your investments at a bad time.

What usually matters more over many years, your savings rate or your choice of securities?

Almost always the savings rate.

Your task

Answer the three questions with your own numbers: the interest rate on your most expensive debt, the size of your cushion, and the amount that really is left at the end of the month. Then use the emergency fund calculator with your monthly fixed costs to work out how many months your cushion lasts. Write a yes or no behind each of the three questions.
