Q: I read your column in Federal Times regularly. I don’t understand how your calculate (in percentages) the return on the Individual funds. Can you share with me how you do the math?
A: Since all dividends and capital gains are retained in the funds, you calculate the percentage return on a TSP fund investment by dividing the fund’s share price at the end of the measurement period by its price at the beginning of the period and multiply the result by 100.
