If I want to calculate a WACC, for year +1, which figures do I use? I thought I would use Equity 52,000 and debt 468,000 from the beginning period and then for year +2 use 85,194 for Equity (paid-in+retained in year1) and 438,529 for debt?

OR do I use 85,194 and 438,529 in year +1? I wasn't sure if we used a t-1 lag.
