    Increases by 0.10%

    The formula to use is:

    WACC = w_d * r_d * (1 – t) + w_p * r_p + w_e * r_e


    And we have:

    w_d = 0.4

    w_p = 0.2

    w_e = 0.4

    r_d = 0.04

    r_p = 0.05

    r_e = 0.09

    t = 0.4


    So, the WACC before the change in tax rate is:

    WACC = 0.4 * 0.04 * (1 – 0.4) + 0.2 * 0.05 + 0.4 * 0.09 = 5.56%

    At the new rate, we have t = 0.35, so the WACC after the change in tax rate is:

    WACC = 0.4 * 0.04 * (1 – 0.35) + 0.2 * 0.05 + 0.4 * 0.09 = 5.64%

    The WACC increases by 0.08%.


    Note that we don't need to do this entire calculation twice if we didn't want to, since the only variable is the change in the debt component. All we needed to do is calculate:

    Change in WACC = w_d * r_d * (t_old – t_new) = 0.4 * 0.04 * (0.40 – 0.35) = 0.08%.

    We know that this is an increase because taxes decrease the cost of capital, so a tax cut would increase the cost of capital.
