One Starter pack and one Growth pack contain 35 credits for a combined $776.40 USD. Divide the total cost by the total credits: $776.40 ÷ 35 = $22.182857… per credit, or about $22.18. This is a weighted acquisition cost, not a new published Pro Max package or a promised customer selling price.
Add quantities and money separately
Starter contributes 10 credits at $228.90. Growth contributes 25 credits at $547.50. The combined quantity is 10 + 25 = 35 credits, and the combined cost is $228.90 + $547.50 = $776.40. Retain both purchase records so the combined figure can be traced back to the actual quantities and totals.
Why a simple average is wrong
Averaging $22.89 and $21.90 gives equal importance to the two packs, even though Growth supplies two and a half times as many credits. A weighted calculation gives each purchased credit the same importance instead. Dividing combined dollars by combined credits keeps the larger purchase represented correctly without needing a separate percentage calculation.
Round for display, retain precision for calculations
The displayed average can be $22.18, but that rounded figure multiplied by 35 gives $776.30 rather than the original $776.40. Keep the full division result in further calculations and round the final USD amount. A few cents of rounding difference should not be mistaken for a missing credit or an unexplained panel charge.
Choose a consistent cost method
This example describes the two packs as one combined pool. It does not tell you whether an accounting system should use weighted average, first-in-first-out or another method. Apply the method used in your own records consistently. Any current panel balance, earlier purchases, nonstandard adjustments and other expenses need separate entries before interpreting a business margin.

An example to work through
If the entire 35-credit pool remains unused, the planning record shows $776.40 of acquisition cost. Displaying about $22.18 per credit is convenient, but the exact purchase total remains the amount to reconcile against those two records.
Questions about this topic
Can I average the two published unit prices?
Not as an equal-weight average when the quantities differ. Divide combined cost by combined credits.
Does the mixed average change the credit deductions?
No. The published 0.1, 0.3, 0.6 and 1-credit term deductions remain the same.
