📘 Dave Ramsey Millionaire Calculator Approach
Ramsey’s “Everyday Millionaire” study shows most millionaires use consistent investing (15% of income) and avoid debt. Use our calculator to simulate 12% mutual fund assumptions, but we recommend conservative 8-9% for 2026 projections. The automatic millionaire calculator relies on dollar-cost averaging.
