Credits, with the units kept clear.

Calculate the required credits.

Credit quantity and calendar time are different.

A credit is the panel accounting unit. The annual deduction is ten credits, so multiplying twelve by the one-month deduction would give the wrong annual allocation. Use the explicit term lookup, not a calendar assumption.

The calculator accepts whole nonnegative counts. It deliberately leaves out three- and six-month selections because their direct deductions have not been supplied. It also does not calculate customer prices, revenue or profit.

A practical package check.

Start with the activations you intend to create, calculate the credits and compare the package quantity. Confirm current expiry, panel privileges and the treatment of unused credits before paying for a top-up.
