What is the WACC with 80% equity at 10% and 20% debt at 5%, taxed at 25%?
8.75%
With 80% equity costing 10% and 20% debt costing 5% before a 25% tax shield, the weighted average cost of capital is 8.75%.
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% × 10%) + (20% × 5% × (1 − 25%)) = 8.75%
The tax shield takes debt's effective cost from 5% to 3.75%.
