Formulas
Future value of a regular savings plan (annuity-due end-of-period). FV = C × ((1+r)^n − 1) / r where r is the monthly rate. Models a periodic savings habit with compound reinvestment.
future_value = monthly_savings * ((1 + annual_rate/12)^periods - 1) / (annual_rate/12); total_deposited = monthly_savings * periods; interest_earned = future_value - total_deposited; interest_ratio = interest_earned / future_value * 100
