How Retirement & 401(k) Savings Are Calculated
Retirement savings are calculated using compound growth, meaning your money grows not only from contributions but also from investment returns earned over time.
Retirement growth depends on:
Starting balance
Regular contributions
Employer match (401(k))
Annual return rate
Time until retirement
Because of compounding, starting earlier — even with smaller contributions — can make a significant difference.
