What it does
Specific historical markets instead of a fixed 8–10% annual assumption
A standard forecast asks you to enter an expected return. The historical scenario instead loads monthly prices for the selected asset and applies the same investing rules to that real period.
Multiple asset classes
Test cryptocurrencies, popular stocks, broad-market ETFs, gold and bonds.
DCA, CS and VA
All three strategies run through the same period, making their results easier to compare under identical market conditions.
Additional assumptions
The scenario can include fees, dividend adjustment for stocks and ETFs, and an inflation view.
How to use it
Five steps from asset selection to strategy comparison
Choose an asset
For example Bitcoin, Ethereum, the S&P 500 through VOO or SPY, Nasdaq-100, gold or an individual stock.
Choose a period
Use a preset 1, 3, 5 or 10-year horizon or select custom start and end months.
Set the investment plan
Enter starting capital, operation amount and frequency, fees and other scenario assumptions.
Configure CS and VA
Set units per operation for Constant Share and the target-value rules used by Value Averaging.
Compare results
Review portfolio value, cash flows, profit, IRR, risk and strategy paths across the same period.
Example scenario
One market period, three different investing rules
Select one asset and one historical window, apply a common investment plan and see how DCA, CS and VA behave differently.
A historical test shows what would have happened in a selected past period. It does not tell you which strategy must perform best in the future.

Three strategies
Compare not only the ending value, but also how capital enters the market
Dollar-Cost Averaging
Invests a chosen amount at regular intervals. The number of units purchased changes as the asset price changes.
Constant Share
Buys a fixed number of asset units per operation, so the cash amount spent changes with the market price.
Value Averaging
Follows a target portfolio-value path and adjusts the operation size according to the gap between the portfolio and that target.
Important
Backtests are sensitive to the selected asset, period, fees and strategy rules. Strong past results do not guarantee similar future results.
Questions
Frequently asked questions about historical calculations
Is this a forecast of future returns?
No. The historical scenario applies selected rules to past market data. Use the standard forecast mode for assumption-based future projections.
Which assets are available?
The calculator includes Bitcoin, Ethereum and other cryptocurrencies, S&P 500 and Nasdaq-100 ETFs, broad-market ETFs, gold, bond ETFs and popular stocks.
Can dividends be included?
Yes. Dividend adjustment can be enabled for stocks and ETFs. It does not affect cryptocurrencies.
Why compare DCA, CS and VA over the same period?
Using the same sequence of prices makes differences in the outcome more attributable to the investing rules themselves.
