# Usage-Based Billing

> On paid plans, your first block of game plays each month is included in your subscription price. Beyond that, extra game plays are billed per unit at a rate that gets cheaper the higher your plan.

Starter, Growth, Pro, and Plus all combine a flat monthly subscription price with usage-based billing for extra game plays beyond what's included.

## **How It Works**

Each plan includes a block of game plays per month at no extra cost — see [Plans Overview](/pricing/plans-overview) for how many. Once you go over that number, each additional game play is billed at a per-unit rate — you're not cut off, and your campaigns keep running.

| Plan    | Cost per extra play |
| ------- | ------------------- |
| Starter | \$0.06              |
| Growth  | \$0.04              |
| Pro     | \$0.02              |
| Plus    | \$0.01              |

<Tip>
  The per-play overage rate gets cheaper the higher your plan — Plus's rate is a sixth of Starter's.

You can also use the **Estimate your monthly charges** calculator on Zestify's App Store listing — enter your expected game plays per month to see a rounded estimate of your total monthly cost on any plan.

## **The Free Plan Is Different**

The Free plan doesn't use usage-based billing. Once your 100 included game plays for the month are used up, your game pauses until your usage resets or you upgrade — see [Plans and Pricing](/getting-started/plans-and-pricing).
