What is the WACC with 70% equity at 10% and 30% debt at 8%, taxed at 21%?
8.9%
With 70% equity costing 10% and 30% debt costing 8% before a 21% tax shield, the weighted average cost of capital is 8.9%.
How it is worked out
Weight each source of capital by its share of the total, then blend the costs. Debt is multiplied by (1 − tax rate) because interest is deductible; equity is not.
(70% × 10%) + (30% × 8% × (1 − 21%)) = 8.9%
The tax shield takes debt's effective cost from 8% to 6.32%.
