FAQ

Q: What if I can’t save 20%? Start with whatever you can — even 5% is better than nothing. Automate your savings and increase by 1% each month.

Q: Should I include debt payments in the 20%? Yes. Minimum debt payments go under “Needs” (50%), but extra payments toward debt reduction count as part of your 20%.

Q: What if my needs exceed 50%? This is common in high cost-of-living areas. Look for ways to reduce your biggest expense (usually housing) or increase income.
