Free Investing Tools
Three calculators every investor should know — built to learn, not to lock you in. No signup, no tracking pixels, no upsell during the calculation. Embed any of them in your own site.
Sharpe Ratio Calculator
Paste daily/weekly/monthly returns, set a risk-free rate, get the annualised Sharpe ratio plus an interpretation band.
Correlation Matrix
Enter 2–10 US tickers. We pull cached daily returns and render the correlation matrix as a heat-coloured table.
Portfolio Builder
Five tickers and weights. Get the portfolio Sharpe ratio, annualised return/vol, sector concentration, and per-name contribution.
