Ask the Tutor ACCA AFM

Tisa Co WACC

JJames85002y ago
When calculating the wacc, after regearing the asset beta to find the cost of equity, why has the wacc formula been flipped upside down? WACC in solution is 12.75% I used the same figures using the wacc formula provided in the exam and got 13.25% MV equity 18 MV debt 3.6 Ke 14.4% Kd 4.5% (18/(18+3.6*0.75)*14.4%) + (3.6/18+3.6)*0.045) 12.5% + 0.00075 = 13.25% Is this acceptable in exam? Also, just to confirm, if we are given the after-tax cost of debt - we do not multiply the debt by (1-T)? Thanks

They haven't flipped the WACC formula - they have used the same as you. However, you have use the formula wrongly. What you should have typed is this: ((18/(18 + 3.6)) * 14.4%) + ((3.6/(18 + 3.6) * 4.5%) = 12.75% I don't know why you had 0.75 in the first term in your equation. Also, I have no idea why you then added 0.75% (Your answer would not be acceptable - the examiners answer is correct). If we are given the after-tax cost of debt (or if we have had to calculate the cost of debt in the normal way (IRR) then we do not multiply by (1-T).
