Why Compounding Matters for Retirement
Compounding gives early contributions more time. Starting 500 a month at 25 versus 35 can produce a much larger difference than the extra contributions; returns are not guaranteed, and starting early gives more time to ride out volatility.
Three variables
Time: longer periods amplify compounding.
Contributions: savings rate is the most controllable.
Return: uncertain, so do not plan on the best case.
Order of operations
Capture the employer match, pay down high-interest debt, then raise savings.
Fees and taxes eat returns; prefer low-cost accounts.
FAQ
Can I catch up if I start late?
You can contribute more or retire later, but the required savings rate is higher.
What return should I use?
Use a conservative long-run assumption and test a range, not one number.
