Key questions answered
How accurate is this Savings Goal Calculator?

Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods, so the balance grows exponentially.
How does compounding frequency affect the result?
More frequent compounding, such as monthly versus annually, produces a slightly higher final balance for the same nominal rate.
