Another KiwiSaver fee calculator

It says the tool will help people "with the complicated task of working out which KiwiSaver fund is most suitable for them."

"Our independent estimate of KiwiSaver fees will help New Zealanders make a more informed decision on which KiwiSaver provider and fund to choose," says Retirement Commissioner Diana Crossan.

The fees analysis was completed by actuaries Melville Jessup Weaver and reviewed by several KiwiSaver providers and independent experts.

One of those is Michael Littlewood, a director of KiwiSaver provider SuperLife. Littlewood went public recently bagging a site which competes with the commission's one.

Crossan says estimated fees are only one thing people should look at when selecting KiwiSaver funds. Other factors include the level of risk (and associated return), service level and communication offered by the fund provider.
