CalcTradeHub is a free multi-category calculator hub: forex position sizing, loan & mortgage EMI, crypto profit & ROI, BMI & BMR, percentages, business days, unit conversion, break-even analysis, and 130+ more calculators — plus in-depth guides that explain the math.
Built this because most calculator sites either cover generic personal finance or niche trading tools, never both well. Would love feedback on which calculator category to expand next — currently strongest in finance, trading/forex, and crypto.
