How compounding builds a 401(k)
Future value = P(1+r)^n + C x (((1+r)^n - 1) / r)A 401(k) grows tax-deferred, so returns reinvest without annual tax drag, and employer matching is effectively free money added to your balance.
Starting earlier matters more than the amount: contributions in your 20s compound for decades, often outweighing larger late-career contributions.
Frequently asked questions
How much should I contribute?
Aim to capture the full employer match first, then raise toward 10 to 15 percent of salary as you are able.
What is the employer match?
Many employers match a percentage of your contributions up to a limit; not contributing leaves that money on the table.
Can I withdraw early?
Early withdrawals usually trigger taxes and a penalty; some plans allow loans or hardship exceptions with restrictions.
