Model three vendors with detailed workload assumptions. Review subtotals, savings, support fees, and blended totals. Make clearer sourcing decisions with consistent cross-cloud cost visibility.
| Provider | Compute Hours | Rate/Hour | Storage GB | Rate/GB | Egress GB | Rate/GB | API Units | Managed Fee | Support % | Discount % |
|---|---|---|---|---|---|---|---|---|---|---|
| AWS | 720 | 0.24 | 1500 | 0.023 | 900 | 0.09 | 1500 | 180 | 8 | 10 |
| Azure | 650 | 0.22 | 1200 | 0.021 | 700 | 0.085 | 1200 | 150 | 7 | 8 |
| GCP | 600 | 0.21 | 1000 | 0.020 | 500 | 0.08 | 950 | 140 | 6 | 7 |
Compute Cost = Compute Hours × Compute Rate
Storage Cost = Storage GB-Month × Storage Rate
Egress Cost = Outbound Data GB × Egress Rate
API Cost = API Request Units × API Rate per Unit
Base Cost = Compute + Storage + Egress + API + Managed Service Fee
Discount Amount = Base Cost × Discount Rate
Discounted Cost = Base Cost − Discount Amount
Support Charge = Discounted Cost × Support Rate
Provider Total = Discounted Cost + Support Charge
Blended Subtotal = Sum of All Provider Totals
Tax Amount = Blended Subtotal × Tax Rate
Contingency Amount = Blended Subtotal × Contingency Rate
Converted Grand Total = (Blended Subtotal + Tax + Contingency) × Exchange Rate
It estimates blended monthly spending across three cloud environments using compute, storage, transfer, API, managed service, discount, support, tax, contingency, and conversion inputs.
Yes. The form includes three provider blocks, so you can model common multi-cloud mixes such as AWS, Azure, GCP, private cloud, or another vendor.
Many enterprise agreements base support charges on discounted spend, not list pricing. This setup helps planning reflect negotiated rates more realistically.
They represent the billing block you use internally, such as ten thousand requests, one million requests, or another metered unit.
Use blended rates for quick planning and exact rates for budget approval. The calculator works with either method as long as your units stay consistent.
Contingency covers growth, burst traffic, under-forecasted demand, or pricing uncertainty. It is added after provider totals to create a safer budget estimate.
The exchange rate is applied to the final blended total. Keep it at one when your output currency already matches source pricing.
Yes. After calculation, use the CSV button for spreadsheet analysis or the PDF button for reports, reviews, and stakeholder sharing.
