FAQ
Is free cash flow the same as savings?
Not exactly. Free cash flow is what remains after bills and planned saving. It can become extra saving, debt payoff, or discretionary spending.
What is a good savings rate?
For normal personal finance, 10–20% is a common target. FIRE plans often require much higher rates.
