CAGR Calculator
Enter a starting value, growth rate, and time period to simulate compound growth. You can also reverse-calculate, for example: "What rate do I need to hit 10 million in a year?"
Compound Growth Simulator with Reverse Calculation
Free CAGR and compound interest calculator. Simulate future growth, reverse-calculate required rates, and compare scenarios — monthly or yearly. No Excel or signup needed.
Choose what to calculate
First, select the appropriate mode from the three options: "Find final value", "Find required growth rate", or "Find required period".
Enter the numbers
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.).
View & share the chart
A chart is drawn as soon as you enter data. Add comparison scenarios or copy the URL to share the results with your team.
Revenue Growth Simulation
Calculate what monthly growth rate is needed to double your revenue from 10k to 20k in one year. (Use Required Growth Rate mode)
Follower Growth Projection
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)
Simulate Future Growth
Enter your current metric and expected growth rate to see the projected future value. Works well for revenue projections, follower forecasts, and more.
Reverse-Calculate Required Growth Rate
Answer questions like "What monthly growth rate do I need to reach 10,000 in a year?" and use it to set realistic targets.
Reverse-Calculate Time to Goal
Find out how long it takes to reach a target — for example, "How many months at 5% growth to hit my goal?" Handy for milestone planning.
Visual Comparison & Image Save
Results appear on a line chart where you can overlay and compare multiple growth patterns. Save the chart as an image for presentations.
Easy Sharing via URL
Your current inputs are reflected in the URL. Copy and send the link so your team sees the exact same simulation.
Export Data to CSV
Export the growth trend as a CSV compound-interest table. Open it in Excel or Google Sheets for further analysis or reporting.
Reverse-calculate KPIs
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.
Predict Follower Growth
Forecast how your follower or subscriber count grows at the current pace, or set milestones towards a target like "reach 100K by next year".
Visualize Daily Improvements
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.
