Savings Calculator Assumptions & Methodology
What This Calculator Shows
This calculator provides a hypothetical illustration of how savings might grow over time. It is not a prediction, projection, or guarantee of future results. Actual investment outcomes will vary and may be significantly higher or lower than the amounts shown.
Return Assumption
The calculator assumes an 8% annual rate of return, based on historical performance of U.S. equity markets. According to data compiled by Professor Aswath Damodaran of NYU Stern School of Business, the S&P 500 has returned approximately 10% annually on average since 1928, and approximately 8% annually since 1957 when the index expanded to 500 stocks.
Our 8% assumption reflects a conservative estimate for long-term equity investing and is applied to UNest's Aggressive (equity-focused) portfolio model.

Your Portfolio Selection Matters
The return assumption above applies to UNest's aggressive portfolio model. If you select a moderate or conservative portfolio, which includes fixed income investments, your expected long-term returns would typically be lower. Your actual results will depend on the portfolio you choose.
What This Calculator Does Not Include
- Fees: Results shown are gross of advisory fees and fund expenses, which will reduce actual returns.
- Taxes: Does not account for capital gains taxes or taxes on dividends.
- Inflation: Returns are shown in nominal terms. Purchasing power of future dollars will be lower than today.
Important Limitations
- Past performance does not guarantee future results. Markets are volatile and returns vary significantly from year to year.
- This is not personalized investment advice. Your actual results will depend on your specific portfolio allocation, contribution timing, and market conditions.
- Year-to-year returns will fluctuate. The calculator assumes a constant annual return for simplicity, but actual markets experience gains and losses that vary widely.
