Common questions

A few things worth knowing before you use the calculator.

What is financial runway?

Runway is how many months your savings can cover your expenses if your income stopped or dropped. It's your savings divided by your monthly burn rate.

What is burn rate?

Burn rate is what you spend each month, net of any income coming in. Spend more than you earn, and that gap is what eats into your savings.
