your savings ÷ one million. that's the whole calculator.
Great question. Terrible answer. This calculator does one thing: divides one million by how much you save each month. No compound interest, no stock market fantasies, no crypto miracles. Just cold, honest, elementary school math. The kind that doesn't care about your feelings.
The formula: (1,000,000 − your current savings) ÷ monthly savings = months until you're a millionaire. Saving $500/month from zero? That's 2,000 months — 166 years. You'll need to be reincarnated. Twice. At $1,000/month it's 83 years. At $2,000/month it's 41, which is almost reasonable. Almost.
$1 million in 30 years of pure savings: roughly $2,778/month. In 20 years: $4,167/month. In 10 years: $8,333/month. If those numbers made you laugh, cry, or both — welcome. This is Depressing Calculators, not Happy Fun Math Time.
Every other calculator assumes 7-10% annual returns forever. That's also what people assumed before every market crash in history. We show the floor — pure savings, zero magic. If you invest wisely, you'll beat our number. If you keep cash under the bed, this is your timeline. You're welcome.
We compare your millionaire age against average life expectancy (EU: 82, UK: 81, US: 78). If your date is past your death date, we'll let you know. Not to be dramatic. Just accurate. You'd still technically be a millionaire. Just not a breathing one.
The median American saves ~$500/month. At that rate with zero returns: 166 years. So can you? Technically. Will you? The math has bad news. But that's why investing, side income, and skipping $7 oat milk lattes exist. This calculator shows the baseline. Everything above it is a bonus.
