I created a free web-based stock calculator that I thought might be helpful for fellow investors. Key features:
Stock Profit Calculator - Quick trading P&L calculations
Average Position Calculator - Easily compute your average cost
Compound Interest Tools - See how your investments can grow
Bond Calculator - Calculate bond prices and yields
ROI Calculator - Track your investment returns
Simple Interest Calculator - Basic interest calculations
Everything is completely free, no ads, no signup required - just simple, clean tools for investors. Works great on both desktop and mobile.
I built this because I was tired of jumping between different calculators for various investment calculations. Would love to hear your feedback and suggestions for additional features!
