I’ve seen this question a few times recently. It usually goes something like “I can set aside x kr. a month for investments. How many months should I save before I invest it?“. The question makes great sense because if you invest too little and too often the brokerage fees might eat up a relatively large percentage of your investment. What people sometimes forget is that if you save up in a savings account for too long to save on fees you are missing out on potential growth. So here I will try to guide you through the process of answering this question for yourself. It should be noted though that the difference you can make will be realtively minor over a long period of time – the most important thing is to save money and get them invested!
