Example Data Table

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

Formula Used

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

Frequently Asked Questions

1. What does this calculator estimate?

It estimates blended monthly spending across three cloud environments using compute, storage, transfer, API, managed service, discount, support, tax, contingency, and conversion inputs.

2. Can I compare more than one provider?

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.

3. Why is support calculated after discounts?

Many enterprise agreements base support charges on discounted spend, not list pricing. This setup helps planning reflect negotiated rates more realistically.

4. What are API request units?

They represent the billing block you use internally, such as ten thousand requests, one million requests, or another metered unit.

5. Should I use blended or exact service rates?

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.

6. What is the contingency field for?

Contingency covers growth, burst traffic, under-forecasted demand, or pricing uncertainty. It is added after provider totals to create a safer budget estimate.

7. Does the exchange rate change all values?

The exchange rate is applied to the final blended total. Keep it at one when your output currency already matches source pricing.

8. Can I export the results?

Yes. After calculation, use the CSV button for spreadsheet analysis or the PDF button for reports, reviews, and stakeholder sharing.
