Once Namecheap initiates the upgrade, you have 14 days to pay the invoice before your hosting is suspended.

Formula (Namecheap official prorated method):
Days Remaining × (New Plan Price − Current Plan Price) ÷ Total Days in Cycle

Understanding Namecheap Prorated Upgrades

If you're outgrowing your current Namecheap shared hosting limits—whether running out of disk space, inode limits, or needing more addon domains—upgrading is the next logical step. However, a major point of confusion for website owners is understanding how much they will actually pay during the transition.

What is Prorated Billing?

Instead of charging you the full price of the new plan and wasting the remainder of your old plan, Namecheap uses a "prorated" system. This means you only act pay for the functional difference between the high-tier and low-tier plan for the exact number of days remaining in your billing cycle. Once your renewal date arrives, you will then be billed the normal renewal rate for the new tier.

How to use this Calculator

We built this tool based on Namecheap's official published mathematical formulas for upgrading. Simply grab your billing start and end dates from your Namecheap Dashboard (under the 'Hosting' tab), select your current and target package, and the tool will compute the exact pro-rated refund and the pro-rated charge to give you the net difference.

Frequently Asked Questions

Will my website experience downtime during the upgrade?
For Shared Hosting upgrades (e.g., Stellar to Stellar Plus), your files remain on the same server or are seamlessly synced by the Namecheap team. Usually, no downtime happens, though brief DNS propagation might occur if moving to a completely new server architecture.
Do I need to migrate my files manually?
No. If you execute a direct upgrade ticket or use the cPanel upgrade module, Namecheap will manage the file transfers and database limits automatically. You do not need to FTP files back and forth.
How long do I have to pay the new invoice?
Once you initiate the upgrade process and an invoice is generated, Namecheap normally allocates a strictly enforced 14-day payment window. If left unpaid, the associated hosting service will face suspension.
