Simply enter the current value, growth rate, and period to simulate future values with compound interest. It also supports back-calculation, such as "What percentage is needed to reach 10 million in one year?".
Calculate compound interest and simulate future growth simply by entering numbers. It supports not only annual (CAGR) but also monthly compound interest calculations. You can also reverse-calculate required growth rates with a single click. A free tool requiring no registration or Excel, useful for everything from sales to follower counts.
First, select the appropriate mode from the three options: "Find final value", "Find required growth rate", or "Find required period".
Enter the current value (initial value) and other required fields like growth rate or period. You can freely change the unit (people, PV, etc.) and period type (monthly, yearly, etc.).
The chart is drawn instantly upon input, allowing you to visualize the trend. You can also add comparison scenarios or copy the URL to share the simulation results with your team.
Calculate what monthly growth rate is needed to double your revenue from 10k to 20k in one year. (Use Required Growth Rate mode)
Project how many followers you will have in a year if you start with 10,000 and grow by 5% every month. (Use Final Value mode)
Simply enter your current metric and expected growth pace to quickly calculate the future value. Great for sales forecasting and asset simulation.
Supports reverse calculations like "What monthly growth rate is needed to reach 10,000 in a year?". Great for goal-based business planning.
Instantly calculate questions like "How many months (or periods) will it take to reach the target if we grow at 5% a month?". Use it when planning schedules or setting milestones.
Results are visualized on a line chart, allowing you to overlay and compare multiple growth patterns. You can also save the chart as an image for use in presentations.
Your current simulation state is directly reflected in the URL. Simply copy and send the link to instantly share the exact same screen with your team members.
You can export the growth trend and simulation results as a compound interest table in CSV format. Import the downloaded data into Excel or Google Sheets to build reports or dig deeper into the numbers.
Quickly reverse-calculate the required monthly (CMGR) or compound (CAGR) growth rate to achieve sales targets or KPIs, and use it for business planning and goal sharing.
Forecast how your follower or subscriber count grows at the current pace, or set milestones towards a target like "reach 100K by next year".
Run the 1.01 rule through this tool — “1% daily improvement makes you 37x better in a year” — and see the compound effect play out with your own numbers.
