Formula Used in 401k Calculation
This calculator uses two main financial formulas:
1. Future Value Growth Formula
The future value of your 401k is calculated using compound interest:
FV=P(1+r)t
PV
$
r
%
n
PV is starting amount; r is rate; n is number of periods.
FV=PV(1+r)n=1(1+0.05)20=2653.3dollars
Where:
- FV = Future Value of investment
- P = Current 401k balance
- r = Annual return rate (decimal)
- t = Number of years until retirement
2. Retirement Withdrawal Formula
Once you retire, your savings are divided over the withdrawal period:
Annual Payout=nFV
Monthly Payout=12Annual Payout
Where:
- n = Number of withdrawal years
Example Calculation
Let’s understand with a real-life example:
- Current 401k Balance: $50,000
- Current Age: 30
- Retirement Age: 65
- Annual Return Rate: 6%
- Withdrawal Period: 20 years
Step 1: Growth Period
35 years of investment growth
Step 2: Future Value
Your investment grows significantly due to compounding.
Step 3: Retirement Income
The total amount is divided over 20 years to estimate income.
