If you want to withdraw Ksh 5,000 from MPESA, it will cost you Ksh 84. According to Safaricom, Ksh5,000 is in the range of Ksh 5,001 and Ksh 7,500.
You can also avoid paying Ksh 84 and pay Ksh 67 by doing this:
Withdraw Ksh 4,951 first and spend Ksh 67, then withdraw Ksh 49 later. Safaricom does not charge customers who withdraw below Ksh50
Employ the trick above for each withdrawal you make.
