Your multiple, also known as the total-value-to-paid-in (TVPI), represents how much your portfolio is worth versus how much you invested. You can calculate your multiple by dividing the amount your investments are worth by the amount you invested.
As reported in the Portfolio dashboard, TVPI is the sum of the value of all investments and distributions after subtracting fees and carry ("net of fees and carry") divided by the total contributed amount.
For instance, if you invested $100k and your investments were worth $150k, and you paid $10k in fees and carry, then your multiple would be 1.4 ((150k-10k)/100k).
