Cost of Waiting to Invest Calculator

More than most people expect, because the years you delay are the ones that would have compounded the longest. Waiting ten years to start investing $500 a month at 7% can cost hundreds of thousands by retirement — often more than half the potential balance — since those early dollars never get their decades of growth.

Compounding is back-loaded: each dollar's growth builds on all its prior growth, so a contribution made 40 years before retirement multiplies far more than one made 20 years before. Skipping the earliest years removes the contributions with the longest runway — the most valuable ones you'll ever make.

No. While starting earlier is dramatically better, starting today always beats starting later still — every year you wait raises the cost. If you're behind, increasing your contribution rate and capturing any employer match can recover meaningful ground even in the last 15–20 years before retirement.

Start anyway. A small amount invested early, then increased over time as your income grows, usually beats waiting until you can invest 'enough.' The habit and the early compounding matter more than the initial size — you can raise contributions with every raise.
