Will your expected API usage fit within the rate limit? This calculator checks your daily request volume against total capacity.
Max Daily Capacity = Rate Limit Per Minute x 60 x 24
Utilization % = (Requests Needed Per Day / Max Daily Capacity) x 100
Example
50,000 requests needed per day, 100 requests/minute rate limit:
Max Daily Capacity = 144,000 → 34.7% utilization - Within capacity with reasonable headroom
Why This Assumes Perfectly Even Traffic
This assumes requests are spread evenly throughout the day - in practice, traffic is rarely perfectly even, with usage commonly concentrated during business hours or specific peak windows rather than distributed uniformly across all 24 hours.
Why Lower Average Utilization Is Safer
A lower average utilization percentage is generally advisable to leave headroom for traffic spikes without hitting the rate limit and getting throttled during peak periods - relying on an average that looks fine but ignores real traffic bursts is a common way to unexpectedly hit rate limits in production.
