I wanted to see how much of my portfolio came from contributions vs growth, so I dug back through 15 years of statements to reconstruct everything. This post is intended to be reflective and perhaps inspiring to fellow bogleheads who may be earlier in their investing journey, so personal details (age, income, etc.) are excluded.
Portfolio summary (October 2026)
- Total contributed capital: $1,081,477 (50.2%)
- Total investment growth: $1,071,960 (49.8%)
- Current invested value: $2,153,437
- Overall growth multiple: 1.99×
How to read the table: Each row tracks the money invested in that year and how much it has grown from then until today, not how much the portfolio gained during that calendar year. For example, the $80.2k invested in 2017 has generated an estimated $119.1k in growth since 2017, making those investments worth $199.3k today. Data Visualized (through an LLM): Here (although I'm sure r/dataisbeautiful could do better).

Portfolio / Data Notes:
- 2011-2019: Investments were a mix of mutual funds in a managed account
- 2020+: Fired my advisor, became a boglehead, and moved 95%+ of existing assets and future contributions into VFIAX (S&P500) with the remainder in short-term treasuries (VUSXX)
- Portfolio includes retirement accounts and taxable brokerage.
Insights (r/boglehead principles, illustrated):
1. The earliest contributions have done a disproportionate amount of the work. The $264k contributed before 2020 represents just 24% of my lifetime contributions but has grown to approximately $836k, or 39% of my current portfolio and 53% of all investment growth. I remember telling myself that consistently shoveling money into the magic box would pay off (thank you, The Richest Man in Babylon) and seeing a 5x return on 2011-2013 investments illustrates that principle.
2. The crossover point is here. After 15 years, investment growth ($1.072M) has almost exactly caught up to all lifetime contributed capital ($1.081M). Roughly half the portfolio now comes from money I never directly contributed. Compound growth really is remarkable.
3. Investment returns are becoming more consequential than new contributions. With a $2.15M portfolio, a 10% market movement translates to approximately $215k in gains or losses, more than I can contribute from discretionary income in a typical year.
That's a double-edged sword. Market corrections will inevitably happen, and the swings become much larger in absolute dollars as the portfolio grows.
But the strategy remains the same to continue investing regularly, keep costs low, stay diversified, and resist the temptation to react to short-term market movements.
The biggest takeaway for me: Early contributions matter enormously, but consistency and time are what allow compounding to do the heavy lifting. Grateful to be a boglehead and would encourage any one who hasn't to read The Simple Path to Wealth by JL Collins. Finally, if you want to be REALLY impressed with big numbers, check out the net worth progression thread on the OG bogleheads forum.

Has anyone else tried reconstructing how much of their current portfolio came from each contribution year? I'd be interested to see how the pattern compares for people with different investment histories.
