Chama / Group savings optimizer
Simulate merry-go-round rotation payouts and welfare fund, or model what your group achieves by investing together.
Common sizes:
Quick fill:
Monthly pool (12 × Ksh 2,000)
Ksh 24,000
Your rotation payout (when it's your turn)
Ksh 22,800
After the 5% welfare buffer — paid in full, one month per cycle.
Cycle length
12 months
Each member gets one turn
Group welfare fund per cycle
Ksh 14,400
Accumulated from monthly buffer
How the math works
In pure cash, every member ends the cycle identically: each pays Ksh 24,000 across the 12 months and receives Ksh 22,800 once, so the cash result is -Ksh 1,200 for everybody — the welfare buffer the group holds back. Going first is not a bigger payout.
What going first is actually worth is the time. Receiving in month 1 is an interest-free loan from the group; receiving in month 12 is an interest-free loan to it. Measured against the 364-day Treasury bill, 7.71% after tax, slot 1 is worth Ksh 1,492 more than the last slot.
That gap is what the group is really allocating when it picks the order — and why rotating who goes first between cycles, or drawing lots each cycle, is the fairness mechanism rather than a formality. Group savings discipline is still the larger return.
