☁️ Cloud Cost Calculator
Enter your instances, hourly rates, storage, and egress to estimate the monthly and annual cloud bill, with compute, storage, and data-transfer broken out so you can see where the spend lands.
💵 Compute, Storage & Egress
What is a Cloud Cost Calculator?
It rolls the main drivers of a cloud bill — compute hours, stored gigabytes, and outbound data — into a single monthly figure and an annualised total. Breaking the estimate into those buckets makes it easy to spot the line item worth optimising, whether that's right-sizing instances or trimming egress.
Use it to sketch a budget or compare scenarios. The numbers are estimates for planning — they exclude discounts, free tiers, and taxes, so verify against your provider's pricing and bill.
❓ Frequently Asked Questions
What goes into a cloud bill?
The three biggest line items for most workloads are compute (instances billed by the hour), storage (charged per gigabyte-month), and egress (data leaving the cloud, charged per gigabyte). This calculator breaks the estimate into those three buckets so you can see which one dominates and where to optimise.
What do the default rates represent?
The defaults mirror common public-cloud list pricing: 730 hours in an average month, roughly $0.023 per gigabyte-month for object storage, and about $0.09 per gigabyte for internet egress. Every rate is editable, so plug in the exact figures from your provider's pricing page for a closer estimate.
Why is egress often the surprise cost?
Compute and storage are easy to picture, but data transfer out of the cloud is metered per gigabyte and adds up fast for busy applications, large downloads, or cross-region traffic. Modelling egress separately here helps you catch it before it shows up on the bill.
Is this accurate enough to budget with?
It's a planning estimate. It deliberately ignores reserved-instance and committed-use discounts, spot pricing, free tiers, support plans, and taxes — all of which can move the real figure substantially. Use it for a first-pass budget, then verify against your provider's calculator and your actual bill.
