Kinsta Add-On Prices: What a Plan Costs Once You Add Sites, Storage and Extras

The listed monthly price of each Kinsta add-on, and the point where adding sites to a single-site plan costs more than moving to a multi-site plan.

Published November 12, 2026 · Prices and terms checked November 12, 2026

A Kinsta plan price covers a set number of sites, visits and gigabytes. Most other things are add-ons with their own monthly price. This page lists them and works out two common cases.

Adding sites or moving up a plan

A single-site plan can take extra sites at $30 each. A multi-site plan includes them. The comparison below starts from the smallest single-site plan, Single 35k at $35 per month.

The price is only part of it. The multi-site plans carry higher limits.

Monthly price$65$70
Monthly visits35,00070,000
Storage10 GB20 GB

For $5 more per month, WP 2 doubles the visit limit and the storage. Adding a site to the single-site plan is lower in price only if both sites fit inside 35,000 visits and 10 GB.

What a plan costs with common extras

One site on Single 65k, with hourly backups and a premium staging environment:

ItemPer month
Single 65k$50
Extra backups, every hour$100
Premium staging environments$20
Total$170

The add-ons in this example cost more than twice the plan itself. $170 is also the price of Single 315k, a plan with almost five times the visit limit.

Storage: add-on or bigger plan

Disk space costs $20 for each extra 20 GB. A single-site plan includes 10 GB up to Single 315k and 15 GB above that. The multi-site plans include 20 GB to 60 GB. Storage-heavy sites reach the add-on quickly on single-site plans.
