See how a small daily profit can turn into great results over time.

Interest doesn’t just sit there — it earns more interest on top of itself, every single day. Type in your starting amount and rate below, and see exactly how fast your money can grow.

 

If you’re new to trading, daily compounding is one of the most important things to understand — it’s how small, consistent daily gains can turn into serious money over time. The calculator below shows you exactly how that works.

Here’s how to use it:

Starting amount — enter how much money you’re putting in (e.g. $1,000)

Interest rate — enter your expected daily return as a percentage (e.g. 0.5% per day)

Duration — enter how many days, months, or years you plan to trade for

Reinvest rate — keep this at 100% if you’re putting all your profits back in, or lower it if you plan to take some cash out each day

Weekends — if you only trade on weekdays, switch this to ‘business days only’

Hit Calculate and you’ll see your projected final balance, total interest earned, and a month-by-month breakdown of how your money grows. You can also download the full breakdown as a spreadsheet using the Export CSV button.
