About InvestCalc

Our Mission

InvestCalc was built to provide investors, students, and anyone interested in personal finance with free, private, and visually engaging tools for financial calculation. No sign-ups, no data collection, no hidden costs — just powerful calculators at your fingertips.

Our Calculators

InvestCalc offers three powerful financial calculators, each designed for a specific investment scenario:

Stock Profit Calculator

Calculate profit/loss, ROI, and net returns for stocks, crypto, and ETFs. Includes buy/sell price inputs, quantity, and transaction fees for accurate calculations.

DCA Calculator

Track dollar-cost averaging across multiple purchases. See your average cost basis, total invested, current value, and unrealized profit/loss at a glance.

Compound Interest

Visualize the power of compound growth with interactive Chart.js charts. Supports monthly contributions, adjustable compounding frequency, and year-by-year breakdown tables.

How It Works

Everything runs entirely in your browser using JavaScript. No financial data is ever sent to any server. The Flask backend only serves the static HTML pages — all calculations are performed client-side.

  • • Stock Profit: Net Profit = (Sell Price × Qty − Sell Fee) − (Buy Price × Qty + Buy Fee)
  • • DCA: Average Cost = Total Amount Invested / Total Shares Purchased
  • • Compound Interest: A = P(1+r/n)^(nt) + PMT×[((1+r/n)^(nt)−1)/(r/n)]

Our Values

Privacy First

Your financial data never leaves your browser. Zero server-side processing, zero data storage.

Always Free

All calculators are free forever. We sustain the service through non-intrusive advertising.

Visual & Interactive

Beautiful charts and tables help you understand your investment growth at a glance.

Accuracy

Precise calculations using standard financial formulas with transparent methodology.
