It's easy to start a budget when the same amount of money rolls in every month. Just minus expenses from this number, stick to it, and there you have it!
But what do freelancers do, given the proverbial "feast or famine" nature of monthly earnings?
One possibility is to base your numbers on percentages instead of hard amounts. If you have an outline of a budget, this is very easy. Instead of committing $100 to gas out of a paycheck of $1000, commit 10%.
Here's what this would look like:
BEFORE:
Income: $1000
Mortgage: -500
Gas: -100
Utilities: -300
Spending: -100
AFTER:
Income: 100%
Mortgage: -50%
Gas: -10%
Utilities: -30%
Spending: -10%
Of course, I fully admit this is very idealistic, and assumes that there is a second income in the family. But it's what I've thought of so far.... So how do you manage your earnings?
