Frequently Asked Questions

How do I calculate compound interest?

Go to the "Compound Interest" tab, enter your initial investment amount, annual interest rate, time period in years, compounding frequency, and optional monthly contributions. Click or type to see the future value, interest earned, and a visual chart showing your investment growth over time. The formula used is: A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) − 1) / (r/n)].

How do I calculate stock or crypto profit?

Use the "Stock / Crypto Profit" tab. Enter your buy price, sell price, quantity, and trading fee percentage. The calculator instantly shows your total cost, revenue, net profit or loss, ROI percentage, and fee breakdown. Works for stocks, ETFs, crypto, and any other traded asset.

What is dollar-cost averaging (DCA)?

Dollar-cost averaging (DCA) is an investment strategy where you invest a fixed amount at regular intervals. This reduces the impact of market volatility on your average cost. Our DCA Calculator lets you enter multiple buy transactions at different prices and calculates your average cost, total investment, unrealized P/L, and ROI.
