FIRE, or Financial Independence, Retire Early, is a fast-growing movement of people looking for a different way in life.
Saving a high percentage of your earnings allows you to retire significantly earlier than traditionally possible. The percentage of your earnings which you save is known as your savings rate. A popular target is to aim for the 50-70% savings rate bracket, allowing you to retire after roughly 9-17 years of work.
This opens a whole world of opportunities for the rest of your life.
