Frequently Asked Questions

The interest rate you enter is the rate per compounding period. If you select "Daily", the rate is applied each day (e.g. 5% daily = 5% earned every day). If you select "Monthly", the rate is applied each month. This matches how Forex, CFD, and margin trading platforms quote their rates. Formula: A = P × (1 + r)^t where r is the rate per period and t is the number of periods.
Yes. Use the Years, Months, and Days fields independently. For example, enter 0 years, 0 months, and 100 days to calculate exactly 100 days of growth. The breakdown table adjusts to show daily, monthly, or yearly rows depending on your time period.
Average price (cost basis) is the weighted mean price paid across all your purchases of a stock. It helps you understand your true entry point when you buy shares at different prices over time.
It shows you the price band above and below a base price. For example, a 5% range on a $100 stock gives Min $95 and Max $105 — useful for setting stop-loss orders and take-profit targets.
Most brokers only allow you to buy whole shares (unless they offer fractional share trading). If your capital buys 101.87 shares, you can only actually purchase 101 — the remaining 0.87 of a share cannot be bought, so the calculator floors the result to the nearest whole number. The "Remaining Cash" result shows you exactly how much uninvested capital you have left over.
