Step 1: Quantify the Gap
Use the DCA calculator to find the gap between where you are and where you should be. If your plan called for $500/month since age 28 and you’re now 38 having invested only intermittently, the gap is the difference between your actual balance and the benchmark balance (from the table earlier in this series).
DCA gap calculation by years missed and amount — additional monthly investment needed to close gap in 5 years
| Years of Missed DCA | Monthly Amount Missed | Gap at 8% Return | To Close in 5 Years, Add |
|---|---|---|---|
| 1 year | $400/mo | $5,700 | $95/mo extra |
| 2 years | $400/mo | $12,200 | $185/mo extra |
| 3 years | $500/mo | $23,000 | $349/mo extra |
| 5 years | $600/mo | $54,400 | $735/mo extra |
Missing DCA in the past is a fixed loss. But future compounding is intact. A 37-year-old who has invested nothing since 33 can still build a $400,000+ portfolio by 60 with $800/month DCA. The past 4 years are gone; the next 23 are fully available.
Step 2: Increase Contribution to Catch Up
The primary recovery tool is increasing contribution rate. For every year of missed DCA, add approximately 15-20% to your base monthly contribution to close the gap within 5 years. This feels aggressive but is usually achievable through elimination of one significant discretionary expense or use of annual tax refund.
Step 3: Use Catch-Up Lump Sums
Annual tax refunds, bonuses, or other windfalls can accelerate recovery dramatically. A $5,000 lump sum invested immediately at 8% return grows to $23,000 in 20 years — the equivalent of nearly 5 years of $300/month in future DCA. Lump sums are the most efficient catch-up tool.
