1. What is the 401k Pension Formula?

The 401k pension formula calculates the future value of regular contributions to a retirement account, such as a Vanguard 401k. It accounts for compound growth over time based on periodic contributions and expected returns.

2. How Does the Calculator Work?

The calculator uses the future value of annuity formula:

\[ FV = PMT \times \frac{(1 + r)^n - 1}{r} \]

Where:

$ FV $ — Future value of the 401k (USD)
$ PMT $ — Periodic contribution amount (USD)
$ r $ — Periodic return rate (decimal)
$ n $ — Number of contribution periods (unitless)

Explanation: This formula calculates the accumulated value of regular contributions growing at a constant rate of return over multiple periods.
