This has not changed. While your rates might change and go up over time, the basic formula for determining your rates should not change.

Figuring out your rate always comes down to valuing your time appropriately. Set a goal of how much you want to make per month or per year and then work backwards to find out how much that means you need to charge per hour and how many hours you need to bill each week to hit that goal.

But remember to account for taxes! You’ll have to pay income tax, so if you want to make $60k and you don't account for taxes, your take home pay will be much lower. I put about 30–40% of everything I make in my business account to save for tax time. I am overestimating because I’d rather have money leftover than not enough!

Does this help?
