Why this isn't trivial
The part people underestimate: compounding monthly growth makes spend curve upward, so linear guesses undershoot within a couple of quarters. In practice the biggest savings come from tracking growth rate and revisiting the projection monthly, so it is worth modelling before you commit.
How it's calculated
We estimate this by applying a monthly growth rate to current spend and compounding it forward. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Why compound instead of add?+
Growth stacks on the new, larger base each month, so spend accelerates.
How often should I revisit?+
Monthly — update the growth rate as real usage data comes in.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
