Understanding Plan Proration: Credits & Charges When Upgrading or Downgrading
What is Proration?
Proration is a billing adjustment that ensures you pay fairly when you change your subscription plan during a billing cycle. When you upgrade or downgrade, we calculate charges based on the time remaining in your current billing period.
Key Points:
- Prorations happen when you upgrade, downgrade your plan, or change the number of seats
- You pay for what you use and receive credit for unused time
- Prorations are calculated automatically by Stripe and our system
How It Works
When you change your subscription, two separate calculations happen:
1. Financial Proration (Stripe)
Adjustments to your subscription charges on invoices. This determines what you pay or receive as a credit.
2. Credit Proration (On Caimera)
Adjustments to available credits in your account balance. This determines how many credits are added or removed.
Both happen at the same time but serve different purposes.
Scenarios
Upgrading Your Plan
If you upgrade on day 10 of a 30-day cycle:
- You'll be credited for the remaining 20 days at your old plan rate
- You'll be charged for the remaining 20 days at your new plan rate
- The difference is added to your next invoice or deducted if you're due a refund
Downgrading Your Plan
If you downgrade on day 15 of a 30-day cycle:
- You'll be credited for the remaining 15 days at your old plan rate
- You'll be charged for the remaining 15 days at your new plan rate
- If the downgrade results in a lower charge, the difference may appear as a credit
- Note: Credit balances can go negative during downgrades, which is normal
Scenario 1: Upgrade Plan
You upgrade from MINI ($15/month) to STARTER ($45/month) on day 10 of a 30-day cycle.
Calculation: ($5 old) + ($30 new) - $15 = $20 additional charge
You're charged an additional $20 immediately.
Scenario 2: Add Seats
You add 1 seat to STARTER plan ($45/month/seat) on day 15.
Prorated charge for extra seat: 15/30 × $45 = $22.50
You're charged $22.50 for the additional seat.
Scenario 3: Change Seats and Upgrade Plan
You change from STARTER ($45/month) with 2 seats to PRO ($117/month) with 3 seats on day 15.
Calculation: ($45 old) + ($175.50 new) - $45 = $130.50 additional charge
You're charged $130.50 immediately. All 3 seats get PRO access.
