SaaS Growth Calculator

Project subscription revenue forward at a compound monthly growth rate and see when it doubles.

About SaaS Growth Calculator

Compounding growth is exponential, not linear: the increase in the final period is far larger than in the first. The doubling figure comes from the logarithmic form and is the quickest sanity check on whether a growth rate is plausible. Capacity and budget plans built on linear extrapolation understate compound subscription revenue growth badly over a three-to-five year horizon.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.
