How we calculate this
Both lines start with your amount, add your monthly top-up, and earn their yearly rate split into twelve monthly amounts that compound. The fund uses the yield its manager publishes; the fixed deposit uses the typical top rate, the median of banks' published maximums, not the single highest.
Tax on unit trust profits and on bank interest isn't confirmed yet, so both lines are before tax and labelled. When a rule is confirmed we apply it here automatically.
