Cloud Server Cost Estimator
Enter your cloud provider, instance configuration (vCPU/memory/disk/traffic), and payment model to estimate monthly cost for AWS, Alibaba Cloud, and Tencent Cloud using built-in reference pricing, with a cross-provider comparison — figures are estimates, not live quotes.

How to Use
- Choose the "Cloud Provider" (AWS, Alibaba Cloud, Tencent Cloud), "Instance Family" (general-purpose / compute-optimized / memory-optimized), and "Payment Model" (on-demand / annual-monthly / reserved instance).
- Enter vCPU count and memory (GB) under "Compute Resources".
- Under "Storage", enter the system disk size and type (SSD/HDD) and the data disk size in GB (always priced as SSD).
- Enter your expected "Monthly Traffic (TB)".
- The page live-updates the total "Monthly Estimated Cost" plus a breakdown into compute/storage/traffic, a bar chart visualizing each cost's share, and a comparison table at the bottom that automatically estimates the same configuration across AWS, Alibaba Cloud, and Tencent Cloud. Click "Load Sample Data" to fill in a sample config: 4 vCPU / 16GB memory / 50GB system disk / 100GB data disk / 1TB traffic.
Features
- Supports any combination of 3 cloud providers (AWS, Alibaba Cloud, Tencent Cloud), 3 instance families (general-purpose / compute-optimized / memory-optimized), and 3 payment models (on-demand / annual-monthly / reserved instance).
- Calculates monthly cost from vCPU count, memory, system disk (SSD or HDD), data disk size, and monthly traffic, breaking the total down into compute / storage / traffic.
- A cost-share bar chart visualizes the relative proportion of compute, system disk, data disk, and traffic within the total.
- A cross-provider comparison table lists compute/storage/traffic/total cost for AWS, Alibaba Cloud, and Tencent Cloud side by side under the identical configuration, useful for provider selection.
- Costs are estimated from a built-in reference price table, with monthly hours approximated at 730; the tool explicitly states "prices are estimates only — refer to each provider's official calculator" and does not pull live vendor pricing.
Use Cases
Quick budget estimate before a cloud migration
Before deciding whether to move to the cloud or switch providers, a tech lead plugs the same vCPU/memory/disk/traffic config into all three providers for a rough first-pass cost comparison.
Estimating infrastructure cost for a new project
During project kickoff, a product manager or architect estimates monthly cloud spend from the anticipated server spec, feeding it into the project budget without visiting each provider's pricing page individually.
Comparing on-demand vs. annual-monthly pricing
An ops engineer toggles the "Payment Model" option to compare on-demand vs. annual-monthly cost for the same configuration, deciding whether a long-running instance is worth committing to a term plan.
Seeing how storage and traffic choices shift the total bill
By adjusting system/data disk size and monthly traffic and watching the cost-share bar chart shift, a team can tell whether storage or traffic is the larger driver of cost and where to optimize.
FAQ
Is this pricing pulled live from the cloud providers?
No. The tool estimates using a built-in reference price table — it doesn't call AWS/Alibaba Cloud/Tencent Cloud's official pricing APIs. Real prices vary by region, promotions, and account discounts; treat the tool's output as an order-of-magnitude reference and check each provider's official calculator for the actual quote.
How is the monthly cost derived from the hourly rate?
The tool uniformly converts on-demand hourly compute cost to a monthly figure using 730 hours/month (roughly 365 days × 24 hours ÷ 12 months), a common convention for cloud cost estimation.
Why can't I choose HDD for the data disk separately?
In the current calculation logic, the data disk is always priced as SSD — only the system disk supports switching between SSD/HDD. This is noted in the page's disclaimer. If your real data disk is HDD, the estimate will run high, so adjust accordingly.
How are the reserved-instance and annual-monthly discounts calculated?
The tool applies a built-in discount factor for each of the three payment models (on-demand / annual-monthly / reserved) to the compute cost. These are simplified estimation values, not the actual discount depth offered by any provider — check the official contract price before purchasing.
Do the three providers in the comparison table use the same pricing logic?
Yes — all three are calculated under the same simplified reference-unit-price framework (vCPU, memory, SSD/HDD, and traffic priced per each provider's own settings) at the identical configuration, aiming to give a comparable order-of-magnitude baseline rather than exactly replicating each vendor's official pricing rules.
