Please note: Umbrella company contractors are normally paid at a higher rate because their rate includes holiday pay and employer's NI. The agency/client will usually offer umbrella contractors 20-25% more than those on the agencies or client's own payroll accordingly. The umbrella calculator assumes that the rate entered is inclusive of the appropriate uplift. BBuffalo's contractor calculator is based on 2009/10 tax data.
