Cost basis uses FIFO — sells consume the oldest lots first. Buy fees added to cost; sell fees reduce proceeds. No API calls. Short selling and margin not modelled. Not tax advice — rules vary (HIFO, LIFO, specific-ID).
Calculate monthly payment, total interest, and full amortization schedule for any fixed-rate loan.
Model investment growth with monthly contributions and compounding. See the curve, not just the number.
Plug in fixed costs, variable costs, and price. Know exactly how many units you need to sell to stop losing money.
