RPS to Monthly Requests Calculator
If you think in RPS, convert to monthly requests to estimate request-based fees and plan capacity. Compare baseline vs peak traffic.
Inputs
Requests per second (RPS)
~75,600,000 requests/day at current utilization.
Utilization (%)
Use this to model peak vs average traffic.
Hours/day
Days/month
Use 30.4 for an average month.
Scenario presets
Results
Monthly requests (est.)
2,298,240,000
Assumptions
2,500 RPS x 35% x 24 h/day x 30.4 days
How to get your inputs
- Inputs: use billing exports, metrics, or logs to get real counts/GB where possible.
- Units: convert throughput (Mbps) or rates (RPS) into monthly units when needed.
- Scenarios: build a baseline and a high-usage scenario to avoid under-budgeting.
Result interpretation
- Utilization is the biggest lever; it represents how long you sustain the given RPS.
- Peak scenarios matter for autoscaling and request-billed services.
Common mistakes
- Using a single average and ignoring peak/incident scenarios.
- Double-counting or missing adjacent line items (transfer, logs, retries).
Scenario planning
| Scenario | RPS | Utilization | Hours/day |
|---|---|---|---|
| Baseline | Average | Typical | Normal |
| Peak | High | Same | Same |
Validate after changes
- Compare your estimate to the first real bill and adjust assumptions.
- Track the primary driver metric (requests/GB/count) over time.

Example scenario
- 2,500 RPS at 35% utilization, 24 hours/day -> estimate monthly requests.
- Peak 230% scenario highlights request surges.
Included
- Monthly request estimate from RPS, utilization, hours/day, and days/month.
- Useful for request-metered services (API gateways, CDNs, serverless).
- Baseline vs peak scenario table for volume spikes.
Not included
- Seasonality, bursty peak shapes, and retries (use scenarios).
- Bandwidth/egress (model separately using transfer tools).
How we calculate
- Requests per month ~ RPS x utilization x seconds in the period.
- Seconds ~ days per month x hours/day x 3600.
- This is a simplified estimate: real traffic varies by seasonality and peaks.
FAQ
Should I use average or peak RPS?
Use average RPS for cost planning, and model peak separately for capacity and scaling.
What does utilization mean here?
It's how much of the time you're near the given RPS (e.g., 30% if you're at peak only part of the day).
