Calculator Inputs
Enter your own rates, usage, and discounts. This estimator uses your numbers, not live marketplace pricing.
Example Data Table
Sample values below illustrate a mixed workload estimate for planning and testing.
| Service Area | Usage Example | Rate Example | Estimated Monthly Cost |
|---|---|---|---|
| Compute | 3 instances × 730 hours | $0.19/hour | $416.10 before multipliers |
| Storage | 1,200 GB | $0.022/GB | $26.40 before redundancy |
| Bandwidth | 800 GB outbound | $0.087/GB | $69.60 |
| Database | 2 units × 730 hours | $0.31/hour | $452.60 before region factor |
| Backup | 500 GB | $0.05/GB | $25.00 before region factor |
| Monitoring | 12 resources | $4.50/resource | $54.00 |
| Support | Standard plan | Flat monthly amount | $100.00 |
Formula Used
Compute Cost = Instances × Monthly Hours × Hourly Rate × Region Multiplier × OS Multiplier
Storage Cost = Storage GB × Storage Rate × Region Multiplier × Redundancy Multiplier
Bandwidth Cost = Outbound GB × Bandwidth Rate
Database Cost = Database Units × Monthly Hours × Database Hourly Rate × Region Multiplier
Backup Cost = Backup GB × Backup Rate × Region Multiplier
Monitoring Cost = Monitored Resources × Monitoring Rate
Subtotal = Compute + Storage + Bandwidth + Database + Backup + Monitoring + Support
Discount Amount = Subtotal × (Combined Discount ÷ 100)
Net Before Add-ons = Subtotal − Discount Amount
Tax = Net Before Add-ons × (Tax Rate ÷ 100)
Monthly Total = Net Before Add-ons + Tax + Contingency
This method gives a flexible planning estimate. It works especially well when you already know your expected usage and negotiated pricing inputs.

Frequently Asked Questions
1) Does this calculator use live cloud pricing?
No. It calculates from the rates you enter. That makes it useful for budgeting, internal quoting, scenario planning, and testing negotiated discounts.
2) Why is there a region multiplier?
Regions can vary in effective cost because of infrastructure, compliance, or internal pricing assumptions. The multiplier lets you model those differences quickly.
3) What does the operating system multiplier do?
It adjusts compute cost when an operating system adds licensing overhead. This is commonly used to reflect higher costs for certain VM configurations.
4) Should I include contingency in cloud estimates?
Yes. A contingency buffer helps cover growth, temporary spikes, logging expansion, and unexpected services that appear after deployment.
5) Can I use this for annual budgeting?
Yes. The calculator shows both monthly and annual totals. Annual figures are simply the monthly total multiplied by twelve.
6) What counts as database units?
Use any consistent database sizing unit, such as vCores, nodes, or managed instances. Keep the rate and quantity aligned with that same unit.
7) Why track cost per 1,000 transactions?
It helps compare workloads of different sizes. Teams often use it to benchmark efficiency across environments, releases, or architectural choices.
8) Can I export results for stakeholders?
Yes. The page includes CSV and PDF download actions so you can share estimates, assumptions, and totals more easily with others.
