All calculators are downloadable Excel spreadsheets that allow you to save and amend your own personal data.With all the spreadsheets, enter your personal data in the purple coloured cells. Returns aren’t easy to predict so my advice is to be conservative, and always enter returns AFTER fees and inflation.

portfolio rebalancing calculator

Asset classes, such as stocks and bonds, can drift away from our preferred ratios over time, due to performing well or poorly. This means we end up taking on too much risk, or not enough risk, which is subotimal. It’s important to ensure you don’t drift too far from your desired asset allocations. An annual portfolio rebalance where you sell from your better performing assets into your not as good performing assets. This calculator will help you work out how much you need to sell and of which asset, in order to restore your original ratios. Further reading on rebalancing here.


The impact of investment fees calculator

This calculator is more comprehensive than the first investment funds fee calculator on this page. Not only can you see your current total fees with the used assumptions, but you can also immediately see the difference between a wide range of fees.

Investment returns vs contributions grid

Similar to the one earlier on this page, except it is a grid. No inputs required. You can immediately see how much of your investment or savings balance is from you and how much is from interest returns over time. It’s different to the earlier calculator in that you can immediately and easily compare the difference in interest rates.

This grid only works starting from zero (your future savings). Otherwise there are an almost unlimited amount of percentage variations.
