Formula and methodology
Formula: WACC=(E/(E+D))×cost of equity+(D/(E+D))×after-tax cost of debt.
Capital weights are calculated from the entered values; the debt input is already an after-tax cost and no jurisdictional tax rule is inferred.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Equity value — minimum 0; maximum 1000000000000
- Debt value — minimum 0; maximum 1000000000000
- Cost of equity — minimum -100; maximum 100
- Supplied after-tax cost of debt — minimum -100; maximum 100
Worked example
| Input | Value |
|---|---|
| Equity value | 600000 |
| Debt value | 400000 |
| Cost of equity | 10 |
| Supplied after-tax cost of debt | 5 |
WACC =8%.
Assumptions and limits
- Equity and debt values are nonnegative and their total is positive.
- Both cost rates are supplied as percentage points for the same period.
- Taxes, flotation costs, changing capital structure, market data, and valuation advice are not modeled.
