Formula: A = P × (1 + r/n)^(n × t), where P is the starting amount, r the annual rate, n the number of times interest is added per year and t the number of years. Monthly deposits are added at the end of each month and earn the same rate. The rate is assumed to stay fixed and results are before tax, fees and inflation. Real savings and investment returns vary and investments can lose value, so treat this as an illustration, not a forecast or financial advice.
