How much money do you need to start investing?

Mexico's most expensive myth is that investing is for the rich. Today you can buy the whole market from a few hundred pesos, and index funds made accessible what once demanded millions. The real barrier is not money, it is not knowing where to start.

The right question is not what amount gets you started, but how much you need for your own goal. Starting at 24 is not the same as starting at 45, nor is wanting twenty thousand pesos a month the same as wanting eighty. Without that calculation, any amount is a shot in the dark.

The 5% philosophy solves the start: set aside five per cent of what you earn — the slice that today goes on things you do not remember — and let compound interest work for decades. The calculator tells you exactly where that pace lands with your data.
