The Cost of Waiting: Why Starting at 25 vs. 35 Costs You $1 Million

Compounding rewards time, not just money. A 10-year delay can erase hundreds of thousands โ€” even a million โ€” from your future portfolio.

Compare your starting age and watch the compound gap grow.

Starting at 25 vs 35

If you invest $6,000 per year starting at 25 and stop at 35, you can still beat someone who starts at 35 and invests continuously. Time compounds faster than extra contributions.

Why time is the multiplier

Each decade adds another compounding layer. The earlier dollars stack returns on returns for longer.

What to do if you're starting later

The fix is simple: increase your savings rate, automate contributions, and avoid more delays. The sooner you start, the smaller the gap becomes.
