Simulator with regular contributions
Starting capital plus monthly contribution: how much you would have had with each strategy compared with the S&P 500 and the 60/40, after commissions and fund costs, with the real annualised return (IRR) of your cash flows.
RebalancingMonthly rebalancing calculator
Enter what you hold and the price of your ETFs: it tells you how many shares to buy or sell to reach the month's signal portfolio, with commissions and a reminder of which sales may be taxable.
Educational and informational content. It is not investment advice or a personal recommendation. The results shown are historical simulations (backtests) using US-listed ETFs; past performance does not guarantee future results and you may lose some or all of the capital invested. Real returns will depend on your costs, taxes, currency and execution timing.
