Cloud Storage Cost Calculator – Estimate Monthly and Yearly Cost

What does cloud storage really cost?

The sticker price of cloud storage, a few cents per gigabyte per month, hides the bill that arrives at the end of the month. Providers also charge for data you download, called egress, for the number of requests and sometimes for minimum storage periods or retrieval. Your data also tends to grow. This calculator estimates the total for six popular object storage services over the time horizon you choose. Enter the data you store now, monthly growth, monthly downloads, requests and the number of months. It ranks the providers and shows the monthly and total cost of each.

The cost components

• Storage: priced per gigabyte per month, with different prices for hot, cool and archive tiers.
• Egress: the charge for moving data out of the cloud to the internet. For websites, media and backups restored often, egress can exceed the storage cost.
• Requests: many providers charge per thousand or million read and write operations.
• Minimums and early deletion: colder storage tiers can have minimum retention periods and retrieval fees.
• Free tiers and discounts: small allowances, committed use and volume pricing can lower the price.

How to use the comparison

Start with your real numbers. Check your current storage in gigabytes and estimate monthly downloads from your analytics or provider dashboard. Then adjust growth to reflect how quickly you add files. Look at the total over twelve or twenty-four months, not only today's cost, because growth changes the ranking. Providers that offer free or very low egress, such as some newer services, often win when you serve a lot of data. Established clouds may be better when you need tight integration with other services, compliance features or global regions.

Choosing more than price

Price matters, but so do reliability, durability guarantees, performance, regions, security features, support and ease of use. Consider how the files are accessed. A backup archive that is written once and rarely read has very different needs from images served to a global audience. Check what happens if you need to leave: some services make export expensive. Also consider data protection laws that may require storing data in particular regions.

Tips for reducing cloud costs

• Delete files you no longer need and set lifecycle rules to remove temporary data automatically.
• Move rarely used data to cheaper storage classes.
• Compress images and videos before uploading. Smaller files cost less to store and deliver.
• Use a content delivery network and caching to reduce repeated downloads.
• Monitor spending with alerts, so a runaway job does not create a large bill.
• Compare quotes again each year, as prices change.

Common mistakes to avoid

• Forgetting egress, which is the most common surprise.
• Assuming a free tier is permanent or large enough for production use.
• Ignoring growth in the plan.
• Choosing the cheapest option without considering reliability and support.

Privacy and limits

Numbers stay in your browser. The default prices are approximate public list prices that change often, so edit them with the figures from your provider's pricing page or a written quote. The estimate does not include taxes, support plans, bandwidth to other cloud services, free allowances, data transfer between regions or one-time migration costs.
