โ FAQ
Should I cut expenses or earn more?
Both. But cutting expenses has an immediate impactโevery dollar saved is a dollar you can invest. Earning more takes time.
Debt payoff vs investing?
If debt interest rate > expected investment return, pay debt first. 20% debt = 20% guaranteed return.
What if I can't invest the savings?
At minimum, put it in high-yield savings. The key is not letting lifestyle creep absorb the freed money.
How accurate is the 8% return assumption?
Historical S&P 500 average ~10% nominal, ~7% real. 8% is a common planning assumption; actual returns vary.
What counts as an expense to cut?
Subscriptions, dining out, coffee, unused memberships, convenience purchases. Start with low-value items.
How do I stick with expense cuts?
Automate the savings immediately. Out of sight, out of mind. Track progress to stay motivated.
