Questions people ask
Should I save or invest for my goal?
For goals under about five years away, savings accounts are safer because investments can fall just when you need the money. For longer goals, investing usually grows more.
What rate should I use?
The rate your savings account pays (APY or AER). Use 0% if you will keep the money in a current account.
Can I save weekly instead?
Yes. The table shows the weekly amount as well. It works out the same over a year.
