What is the WACC with 80% equity at 12% and 20% debt at 5%, taxed at 21%?
10.39%
With 80% equity costing 12% and 20% debt costing 5% before a 21% tax shield, the weighted average cost of capital is 10.39%.
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.
(80% × 12%) + (20% × 5% × (1 − 21%)) = 10.39%
The tax shield takes debt's effective cost from 5% to 3.95%.
