Portfolio Calculator (Simulator) Instructions

This calculator simulates (backtests) a portfolio of ETFs or mutual funds (we also support stock tickers).

Portfolio Holdings: You enter the target (allocation) holdings in the Portfolio Holdings box in the following example format:

SPY   45.5%
VNQ   14.5%
BND   40%

Each line should have a form of

Symbol Percentage%.

Symbol is a ticker symbol of an ETF or a mutual fund. Examples are like VTI (Vanguard Total Stock Index ETF) or VBMFX (Vanguard Total Bond Index Mutual Fund). You can also enter CASH for the purpose of Cash holding.

Percentage% should be a positive number followed by %.

The percentages should sum up to 100%

Start date: You can specify the start date for the simulation (backtesting). By default, the simulator automatically finds the earliest start date when all holding funds have price data.

Rebalance frequency: You can also specify rebalance frequency that can be either monthly, quarterly, annually, or no rebalance. Rebalance means at the interval specified, the portfolio will sell and buy some existing holdings to bring back the allocation (percentage) of the symbols back to the initial allocation (the target allocation).
