The study used secondary data obtained from 11 pension fund Administrators and the National Pension Commission for a period seven years 2010 – 2016. This study made use of panel data and used multiple regression analysis to use analyze the data with the help of the Eviews9 statistical package. The model proved to be statistically significant with a combined probability of F-statistics of 0.0000 which is below the adopted level of significance of 5%. Age of the fund was found to have a positive significant effect on financial performance of the fund with a p-value of 0.0000. Expenditure was proven to have an insignificant effect on financial performance with a p-value of 0.4819. Contribution Density was found to have a negative significant effect on financial performance with a p- value of 0.0002. Idle Contributions where proven to have a significant positive effect on the financial performance of pension funds with a p-value of 0.0131. It was concluded that age, contribution density and idle contributions had significant effects on financial performance measured by unit price while expenditure did not have a significant effect on financial performance of pension funds in Nigeria. The study recommends that older pension funds, pension funds that manages smaller contributions and pension funds with ample idle contributions share are more likely to have better financial performance in Nigeria.
