(WACC)
Weighted Average Cost of Capital (WACC) H¡${nQ>b H$s doQ>oS> EdaoO H$m°ñQ> (WACC) H$mo
is commonly referred to as the firm's cost of gm‘mݶV… g§ñWm Ho$ H¡${nQ>b H$s H$m°ñQ> H$hm OmVm h¡& Bgo
capital. It is dictated by the external market ~mø ~mOma go nVm bJm¶m OmVm h¡ Z {H$ ‘¡ZoO‘|Q> Ûmam&
and not by management.
WACC is a calculation of a firm's cost of WACC g§ñWm Ho$ H¡${nQ>b H$s H$m°ñQ> h¡ {Og‘|
capital in which each category of capital is H¡${nQ>b H$s à˶oH$ loUr H$mo AmZwnm{VH$ ê$n go aIm OmVm

A firm's WACC increases as the rate of EH$ g§ñWm H$m WACC ~‹T>Vm h¡ O~ Bp³dQ>r na

an increase in risk.
To calculate WACC, multiply the cost of WACC H$s JUZm H$aZo Ho$ {bE à˶oH$ H¡${nQ>b

The WACC formula seems easier to WACC ’$m°‘y©bm H$s JUZm H$aZm dmñVd ‘| gab
