Frequently Asked Questions
The future value is calculated using the formula for the future value of a series with an initial lump sum: FV = P * (1+r)^n + PMT * ((1+r)^n - 1)/r, where P is current savings, PMT is annual contribution, r is annual return rate, and n is number of years until retirement.
The monthly income is estimated by assuming you withdraw from the retirement fund over 30 years after retirement, using the same expected return rate.
Inflation reduces the purchasing power of money over time. The inflation-adjusted future value shows what the lump sum would be worth in today's dollars.
