How do you calculate Instagram follower growth?

Two methods. Fixed pace: current followers + (new followers per month × number of months). Compound pace: current followers × (1 + monthly rate)^number of months. The simulator applies either one depending on the mode you pick, for 3, 6 and 12 months.

How do I find my current growth rate?

Compare your follower count 3 months ago and today, then divide the difference by 3 for a monthly average. For a percentage, divide that average by your starting follower count.

What's the difference between linear and percentage growth?

Linear growth adds the same number of followers each month. Percentage growth applies a rate to a growing base: the gap widens over time, but it's harder to sustain.

Are the simulator's results reliable?

It's a mathematical projection of the pace you enter, not a forecast. Real growth depends on posting consistency, content, niche and the algorithm. Use it to set a realistic goal.

Where does the "with Propulse" estimate come from?

It uses the ranges of new qualified followers per month shown on our pricing page: 250 to 350 (Visibility plan), 350 to 800 (Growth plan), 500 to 1,000 (Acquisition plan). The simulator picks the first plan whose whole range is at least your current pace (in percent mode, your first-month gain). If your pace already exceeds every plan, no Propulse projection is shown. It's an estimate, not a guarantee: results depend on the account and its niche.

Is the simulator really free?

Yes, no signup and no credit card. No data is sent: the calculation runs in your browser.
