How to use this calculator
What this calculator does
Forecast monthly API spending and total usage expenditure under a stated compound request-growth scenario.
How to use it
Enter current monthly request volume, a monthly compound growth assumption, projection length and tokens/prices per request. Compare the final-month and cumulative totals.
What the result means
Even falling unit prices may not offset rapid usage growth. The model holds per-request tokens and tariffs constant so growth effects are visible.

Actual AI costs depend on provider pricing, model choice, token usage, discounts, caching, retries, batching, tool calls, workflow design, and usage volume.
Scenario guidance
When to use this
Use when budgeting a growing AI feature with usage-sensitive billing.
Example scenario
A startup estimates API expenditure if monthly adoption increases 10% repeatedly.
Inputs that usually matter most
- Starting volume and compounded monthly growth
- Actual token mix and rates
Common mistake to avoid
Do not assume today's low token spend remains unchanged as volume compounds.
How to interpret the result
Compare a conservative growth curve with a high-demand scenario.
Rates and assumptions are illustrative and may differ from real provider billing, business outcomes and service availability.
Formula
Applies a constant monthly compound growth rate and fixed price/token mix; vendor price cuts, routing changes, usage caps, churn and context growth are excluded. This is a forecast scenario rather than a prediction.
Worked planning example
At 100,000 current requests, 10% monthly growth, 1,200 input and 300 output tokens with $0.50/$2 per million rates, current direct spend is $120/month. Month 12 reaches about 313,843 requests costing $376.61.
Frequently Asked Questions
Does the model include future token price changes?
No. It keeps input/output rates constant over the projection to isolate usage growth.
Why is cumulative cost greater than final-month cost?
The cumulative figure sums every projected month from month one through the selected end month.
