Members of workplace pension schemes run by Friends Life increased by 4% between 2010 and 2011, the insurer said.
This kept contribution rates increasing at largely the same rate as inflation, according to the Friends Life Workplace Savings Index.
The average monthly contribution rose from £267 in Q2 2010 to £276 in the same quarter of 2011, the insurer said.
Total returns on members' portfolios increased by 15% over the same period, whilst the level of risk experienced by savers fell from 13.1% 12 month trailing portfolio risk to 8%.
The flight from equities, sparked by the Greek debt restructure in summer 2011, led to many Friends Life customers de-risking their pension fund and diversifying their asset allocations away from equities.
This meant many investors' pension funds had lower average risk levels than the FTSE 100 index, Friends Life said.
