About Paybill fees
Safaricom Paybill is the M-PESA channel for paying registered businesses, government agencies, banks, schools, churches, and utilities. The customer pays a per-transaction fee that scales with the amount, set by Safaricom and identical regardless of the paybill recipient.
The schedule is bracketed: KES 100 or less is free, then fees climb gradually until they cap at KES 105 for transactions over KES 50,000. The calculator above looks up your exact bracket and shows the fee in one place.
