Frequently Asked Questions
What is compounding frequency?▾
It is how often interest is added to the balance and starts earning its own interest. More frequent compounding (monthly over annual) produces a slightly higher future value at the same nominal rate.
Does the contribution compound too?▾
Yes. Each contribution earns returns on itself, but because it is added later it compounds for a shorter time than the initial principal. This is why regular contributions dramatically increase the final corpus.
