The Logic Behind It
The calculator solves for the time needed to reach the goal using the compound interest formula with monthly contributions:
t = log((FV * r/n + PMT) / (P * r/n + PMT)) / (n * log(1 + r/n))
Where:
- t = Time in years
- FV = Future Value (Goal Amount)
- P = Initial Principal (Initial Savings)
- PMT = Monthly Contribution
- r = Annual Interest Rate (as a decimal)
- n = Number of times interest is compounded per year (12 for monthly)
This formula calculates the time to reach the goal, accounting for initial savings and monthly contributions, compounded monthly.
