Frequently asked questions

What does compounding frequency change?: More frequent compounding (e.g. daily vs annually) earns slightly more, because interest is added — and starts earning — sooner.
Does this include monthly contributions?: No — this is for a single lump sum. Use the Investment Growth Calculator to add regular monthly contributions.
