Step-Up DCA: Lower Starting DCA, Same $1 Million Goal
A step-up DCA increases your monthly DCA by a fixed percentage each year — matching your salary hikes. The result: you start with a lower DCA but still reach the same goal. Below is a comparison for a 12% return, 10-year target of $1 Million:
Regular DCA (no step-up)
5% annual step-up DCA
10% annual step-up DCA
A 10% annual step-up allows you to start with just $24,000/month instead of $43,000 — a 44% reduction in starting DCA amount, while still reaching $1 Million in 10 years.
The Biggest Factor: Time
The table above shows that extending your DCA from 10 to 20 years at 12% reduces your required DCA from $43,000 to just $8,000/month — a 5x reduction. This is the power of compounding. The longer you invest, the less you need to invest each month.
💡 Key insight
Starting a $8,000/month DCA at age 25 will reach $1 Million by age 45. Waiting until 35 requires $43,000/month for the same goal. 15 years of delay costs $35,000/month extra.
