What is compound interest?
Compound interest means that the interest you earn in one period is added to your principal, so in the next period you earn interest on a larger base. This creates exponential growth: the longer your time horizon, the more dramatic the effect.
Which rate should I use?
The Ibovespa, Brazil's main stock index, has historically returned roughly 12%/year in nominal terms over long periods. The CDI, the interbank interest benchmark, sits around 11% and tracks the Selic rate. The poupança (savings) pays about 6%, while inflation (IPCA) has run near 5%. Nominal Brazilian returns look high next to US figures mainly because inflation is higher, so compare real (inflation-adjusted) returns when planning.
Formula used
FV = PV × (1+r)^n + PMT × ((1+r)^n − 1) / rwhere r is the monthly rate, n is the number of months, PV is the initial investment, and PMT is the monthly contribution. Annual rates are converted to monthly viar = (1 + annual%)^(1/12) − 1.
