# How to calculate return on investment for an adjustment to a complex options position?

Say I currently hold a set of options positions with the same symbol/expiry that collectively have a net present value based on the estimated value at expiration of +10. I could also liquidate the positions now at a value of +6.

I am considering a set of multiple transactions with the same symbol/expiry. If I executed these transactions, I would net +8 including commissions. The estimated present value at expiration for the resulting positions would decline by -3 to 7. I could also liquidate the entire position after the transactions at a value of +5.

How to I determine the ROI of executing these transactions?
