WACC Calculator
Estimate weighted average cost of capital from manually entered common equity, debt, preferred equity and tax assumptions.
Use market capital amounts in one currency and scale; enter 0 for an absent capital class and its cost. Total capital must be positive. The company-level cost applies to company cash flows with matching risk, currency and rate period. Debt interest receives the assumed corporate tax shield; common and preferred equity do not. Rates are user assumptions, not advice.

Formula
V = E + D + PS; wE = E/V; wD = D/V; wPS = PS/V; WACC (%) = wE × Ke + wD × Kd × (1 − T/100) + wPS × Kp.
