EBIT = Sales - Costs - Depreciation
= 123,000 - 57,000 - 12,600
= $53,400
EBIT = EBT as no interest in question.
Tax = EBIT * Tax rate
= 53,400 * 35%
= $18,690
Operating cashflow = 53,400 + 12,600 - 18,690
= $47,310
= Sales - cost - tax
= 123,000 - 57,000 - 18,690
= $47,310
= (Sales - Cost) * (1 - Tax rate) + (Depreciation * Tax rate)
= (123,000 - 57,000) * (1 - 35%) + (12,600 * 35%)
= $47,310
= (Sales – Cost – Depreciation) * (1 - Tax rate) + Depreciation
= (123,000 - 57,000 - 12,600) * ( 1 - 35%) + 12,600
= $47,310
