How this calculation works
WACC = (E/V)×Re + (D/V)×Rd×(1−Tax rate)
Enter the labelled inputs. Percent fields use 5 for 5%. Simplified formula; include other capital classes if needed.
A worked example
Equity market value: 600000 USD; Debt market value: 400000 USD; Cost of equity: 10 %; Cost of debt: 5 %; Tax rate: 25 %. Weighted average cost of capital: 7.5%.
Assumptions and limitations
Simplified formula; include other capital classes if needed. All monetary inputs must use one currency and time period unless conversion is explicit. Manual inputs only; no live prices or official rule tables.
