Your savings rate is the percentage of your monthly income that you actually keep — after every expense, including the ones you forget. Most diaspora underestimate their expenses by 20-30%, which throws off every other part of your return planning.

Understanding the numbers
Savings rate is calculated by dividing your monthly savings (income minus expenses) by your monthly income, then multiplying by 100. A 25% rate means for every $100 earned, you keep $25. This is the single most predictive metric of your ability to fund a return — more than income itself.
Why? Because two people with very different incomes can have the same savings rate — and therefore the same savings velocity. Someone earning $4,000 and saving $800 (20%) is progressing at the same pace as someone earning $8,000 and saving $1,600 (20%). The rate, not the amount, determines your return timeline.
What to aim for
- 10-15% — Beginner. You're building a base. Return is still distant.
- 20-30% — Solid progress. You can plan a return in 5-7 years.
- 30-50% — Accelerating. Return possible in 3-5 years.
- 50%+ — FIRE mode. Return possible in 2-3 years depending on your target cost of living.
For the African diaspora, the savings rate is often dragged down by family obligations — what many call the 'black tax'. That's why we have a dedicated calculator to quantify that burden separately, so you can see its true impact.
