The 'Black Tax': I Finally Put a Number on It
How much does supporting family back home actually cost? I ran the numbers for 3 diaspora personas — and the results were sobering.

Every diaspora knows about the 'black tax' — the money we send home to parents, siblings, and community. It's the most culturally specific financial obligation in our lives, and Western financial advice completely ignores it. Try telling a financial advisor in Dubai that you send 20% of your income to family in Cameroon and watch them struggle to categorize it.
But here's the thing: most of us don't actually know how much we're spending on family support. We know the recurring monthly amounts — the $200 to Mom, the $150 for a sibling's school fees — but we forget the lumpy stuff. The weddings. The funerals. The emergency requests that come 3-4 times a year and average $300-500 each.
So I built a calculator to quantify it. Then I ran it with three diaspora personas to see how the burden scales across income levels.
The Three Personas
I use three hypothetical diaspora profiles in my content instead of sharing my real numbers. This serves the whole audience because everyone can find the persona closest to their situation:
- The $2K/mo diaspora — entry-level, sending $200-400/month to family
- The $4K/mo diaspora — mid-career, sending $400-700/month
- The $8K/mo diaspora — high earner, sending $800-1,500/month
What the Numbers Show
When I ran the Family Obligations calculator with all three personas, the results were sobering. The $2K diaspora — earning $24K/year — was spending 18-25% of their income on family support. That's nearly a quarter of everything they earn, gone. At that rate, saving for return becomes almost impossible without either increasing income or having an honest conversation with family about scaling back.
The $4K diaspora was spending 15-20% — still significant, but leaving more room for savings. The $8K diaspora was at 10-15%, which feels more manageable but still represents $9,600-$14,400 per year that could otherwise go toward return planning.
Across all three personas, the annual events (school fees, weddings, funerals) added 30-50% on top of the monthly recurring amounts. This is what most people underestimate. The monthly figure feels manageable; the annual total doesn't.
The Uncomfortable Truth
The 'black tax' is real, culturally important, and not something I'm suggesting you stop paying. Family obligations are family obligations. But you need to know the number. You need to see it on a screen, calculated honestly, so you can make informed decisions about the trade-off between family support and your return timeline.
For me, quantifying the black tax changed my perspective. I wasn't overspending on family — my amount was reasonable for my income. But seeing the 5-year projection, with 5% annual escalation, made me realize that if I didn't increase my income, the family burden would slowly eat my return savings. That's not a guilt trip. That's just math.
Try It Yourself
The Extended Family Obligations calculator takes about 7 minutes. Enter your monthly recurring support, your annual events, your average emergencies, and a projection period. It'll show you your total family burden over 5 years — and what that money would need to be replaced by post-return.
The number might surprise you. It might also be the conversation starter you need — with yourself, with your spouse, or with your family — about what sustainable support looks like as you plan your return.
