What is a good contractor loading percentage in Qatar?
5% to 12% is a reasonable range for a PAYG/agency contractor, since the agency employs you formally and you keep accruing Article 54 end-of-service gratuity just like a permanent employee. A freelance-permit or QFZA-licensed contractor invoicing directly typically needs a higher 12%-22% loading, mainly to self-fund the gratuity lump sum they don't accrue at all, plus unpaid leave and job security.
