How much do you need to start?

#The mistake hidden behind "I do not have enough money"

This is the most common excuse for postponing investing. But of the three variables that decide the long-term outcome, the starting amount is the weakest.

#The engine of compound growth

In compound growth, gains ride on top of gains. That is why time does not work linearly - it works with acceleration. Making the same contribution five years earlier can be more powerful than a much larger one-time amount.

In the calculator below, play with the three variables separately. In particular, try this: hold the starting amount fixed and extend the time - then hold the time fixed and grow the starting amount. See for yourself which makes the bigger difference:

#A regular contribution beats a one-time amount

A small but regular contribution has two advantages over a large one-time amount:

1. It builds a habit. Investing becomes a routine, not an event.
2. It removes timing pressure. The question "should I get in now or wait?" disappears - because you get in every month.

The second point matters more than it looks: the most expensive mistake new investors make is never starting while waiting for "the right moment".

#So how much do you really need to start?

The right answer is not a number, it is a rule: the amount you can set aside regularly without disrupting your life. Because a plan you cannot sustain is worse than the best plan.

A practical frame:

• The amount should not touch your emergency fund
• It should not disrupt your essential expenses
• It should be reducible in a bad month - it should not have to drop to zero
