What's better: an ETF savings plan or a fund savings plan?

As a rule, fund savings plans are very expensive. If you actually take into account all the costs, it's often the case that 2% or more of the returns are lost to fees – every year. ETF savings plans are significantly cheaper. As a rule, they charge less than 1% fees on net returns. You should also consider that fund savings plans mostly contain actively managed investment funds, the vast majority of which fail to outperform their index consistently. By contrast, ETFs replicate a given index, which not only costs less, but is often also more successful.
