When will your team hit its storage limit, and what will it cost to get there?

Proof: Teams adding 500 files per month at 5 MB each consume 29 GB per year at baseline, but with 5% monthly growth that jumps to over 40 GB in the same period.
Storage costs grow faster than most teams expect because file volume compounds over time. Use this forecaster to see exactly when you will hit your limit and what it will cost.
- A team using 250 GB today, adding 500 files at 5 MB each with 5% monthly growth, will reach 1 TB in about 20 months.
- Storage costs scale with usage. A $50/month bill at 250 GB becomes over $200/month as you approach 1 TB.
- Proactive cleanup and deduplication can extend your runway by 30 to 50 percent without upgrading your plan.

Storage limits sneak up on teams. The files you add each month are not constant. As your team grows and projects accumulate, file volume compounds. This tool models that compounding so you can plan upgrades, budgets, and cleanups before you hit a wall.

Why this matters
Running out of storage is not just an IT problem. It affects costs, performance, and compliance across your entire organization.
Budget surprises
Storage costs scale with usage, but budgets are set annually. A 5% monthly growth rate means your storage doubles in 15 months. Teams that do not forecast end up requesting emergency budget increases or scrambling to delete files under pressure.
Performance degradation
As storage fills up, systems slow down. File searches take longer, backups run past their windows, and sync clients struggle with large repositories. By the time users notice, you are already past the point where simple cleanup fixes the problem.
Compliance risk
When teams hit storage limits, the first instinct is to delete old files. But in regulated industries, retention policies require keeping documents for years. Forecasting lets you plan tiered storage instead of choosing between compliance and capacity.
Duplicate files are the biggest source of storage waste. Renamed.to identifies and organizes redundant files so you reclaim space without losing anything.

Frequently asked questions
How is storage growth calculated?
The calculator projects storage month by month. Each month, the number of new files is multiplied by the average file size to get storage added. The file volume grows by your specified monthly growth rate, compounding over time. This accounts for the fact that growing teams tend to add more files each month, not a fixed amount.
What about compression and deduplication?
The calculator uses raw file sizes without accounting for compression or deduplication. If your storage provider applies compression, your actual usage may be lower than projected. However, many file types like images, videos, and already-compressed documents see minimal compression benefit. The projection is intentionally conservative to help you plan ahead.
What if I add more users over time?
The monthly growth rate parameter accounts for increasing file volume over time, whether that comes from more users, more projects, or both. If you expect to double your team in a year, set a higher growth rate. A 5 to 10 percent monthly growth rate is typical for scaling teams.
How can I reduce my storage growth rate?
Three effective strategies: First, deduplicate files regularly since teams often save multiple copies of the same document. Second, enforce consistent naming conventions so people can find existing files instead of creating new copies. Third, tier your storage by moving infrequently accessed files to cheaper cold storage. Tools like renamed.to help with the first two by automatically organizing and deduplicating files.
Is any of my data sent to a server?
No. All calculations run entirely in your browser using JavaScript. No data is sent to any server, no cookies are set, and nothing is stored. You can use this tool on an air-gapped machine and it will work identically.
