Calculator Inputs
This form uses a responsive 3-column layout on large screens, 2 columns on medium screens, and 1 column on mobile devices.
Example Data Table
These sample rows are illustrative only and help users understand how different workload patterns affect cost totals.
| Scenario | Instances | Hours / Day | Hourly Rate | Storage GB | Transfer Out GB | Estimated Monthly Total |
|---|---|---|---|---|---|---|
| Development Web Tier | 2 | 10 | 0.065 | 120 | 150 | USD 79.40 |
| Always-On Production App | 4 | 24 | 0.096 | 500 | 900 | USD 486.48 |
| Analytics Batch Cluster | 6 | 8 | 0.155 | 900 | 300 | USD 381.60 |
Formula Used
1) Compute Cost
Billable Hours = Instance Count × Hours Per Day × Days Per Month
Discounted Compute = Billable Hours × Hourly Rate × (1 − Discount %)
Total Compute Cost = Discounted Compute + (Upfront Fee ÷ Amortization Months)
2) Storage and Performance Cost
Total Storage Cost = (Root GB + Additional GB) × EBS Rate Per GB-Month
Extra IOPS Cost = Max(Provisioned IOPS − Included IOPS, 0) × IOPS Rate
Extra Throughput Cost = Max(Provisioned Throughput − Included Throughput, 0) × Throughput Rate
3) Network and Supporting Services
Transfer Cost = Data Transfer Out GB × Transfer Rate
Elastic IP Cost = IP Count × Hours Per Day × Days Per Month × Hourly Rate
Snapshot Cost = Snapshot Storage GB × Snapshot Rate Per GB-Month
4) Final Total
Subtotal = Compute + Storage + IOPS + Throughput + Snapshot + Transfer + Elastic IP + Monitoring + Other
Total Monthly Cost = Subtotal + (Subtotal × Tax %)
How to Use This Calculator
- Enter a currency, instance label, region label, pricing model, and operating system.
- Provide workload values such as instance count, hours per day, days per month, and the hourly compute rate.
- Add discount percentage or upfront commitment cost when modeling reserved pricing or savings commitments.
- Enter storage values for root volume, additional volume, EBS rate, IOPS, and throughput pricing.
- Fill in snapshot storage, transfer out data, Elastic IP charges, monitoring, and any other monthly expenses.
- Click Calculate EC2 Cost to display the result above the form.
- Review the cost breakdown table and Plotly chart for better budget visibility.
- Use the export buttons to download the result as CSV or PDF.
Frequently Asked Questions
1) Does this calculator pull live cloud pricing automatically?
No. It uses the values you enter. That keeps the result flexible for different regions, operating systems, discounts, and private pricing arrangements.
2) Can I use this for reserved pricing estimates?
Yes. Enter your reduced hourly rate, any discount percentage, and optional upfront commitment fee. The page amortizes the upfront fee across the number of months you choose.
3) Why are storage and compute separated?
Compute and storage often scale differently. Separating them helps you see whether the bill is driven by runtime, EBS capacity, performance settings, or data movement.
4) What does the IOPS field represent?
It models provisioned storage performance. If you choose gp3, the calculator subtracts included baseline performance before charging extra IOPS and throughput.
5) Can I estimate bursty or partial-day workloads?
Yes. Lower the hours per day or days per month to reflect environments that run only during business hours, test windows, or scheduled analytics jobs.
6) Is tax included in the total?
Yes. Enter the tax percentage you want applied. The calculator adds it after all monthly infrastructure costs are summed together.
7) What should I place in other monthly costs?
Use that field for support allocations, third-party security tools, backup software, management overhead, or any recurring charge not already captured elsewhere.
8) When should I export the results?
Export after you finalize a scenario. CSV works well for spreadsheets, while PDF is better for stakeholder reviews, handoffs, and budget approval discussions.
