Maverick Spending Rate

Percentage of purchases made outside of approved procurement processes. It is most useful as a repeatable operating measure, with the same scope and cut-off applied each time.

Business context

Calculation

Maverick Spending Rate formula

(Maverick Spend ÷ Total Spend) × 100

Formula components

Maverick Spend
The monetary amount assigned to maverick spend for the same scope and reporting period used by Maverick Spending Rate.
Spend
The monetary amount assigned to spend for the same scope and reporting period used by Maverick Spending Rate.
Reporting period
The consistent day, week, month, quarter, or year covered by every input.

How to calculate Maverick Spending Rate

  1. Define the business scope, reporting period, and the event or status that qualifies for Maverick Spending Rate.
  2. Collect each input in the workbook formula from systems that use the same cut-off and unit.
  3. Remove duplicates and exclusions according to the documented rule, while retaining a reconciliation count.
  4. Apply (Maverick Spend ÷ Total Spend) × 100 and label the result with its period, unit, and relevant segment.
Worked example

Maverick Spending Rate example

A fictional supply chain team calculates Maverick Spending Rate for one agreed reporting period.

  1. Maverick Spend = £68.
  2. Spend = 800.
  3. Maverick Spending Rate = £68 ÷ 800 × 100 = 8.5%.

Maverick Spending Rate is 8.5%.

About 8.5 in every 100 eligible units meet the metric’s stated condition.

How to interpret the result

Compare Maverick Spending Rate over a consistent cadence and break it down only by segments large enough to support a decision. Review the formula inputs beside the result so teams can distinguish a real operating shift from a denominator or mix effect.

There is no single target that fits every organisation. Interpretation depends on product type, network design, geography, supplier terms, service promise, seasonality, and measurement period. Document the comparison group before labelling a result strong or weak.

Common mistakes and limitations

Inconsistent scope
Changing the included business units, products, channels, or populations makes the trend look different even when underlying performance is unchanged.
Mismatched periods
Formula inputs from different cut-off dates or time windows do not describe one coherent result.
Mixing accounting treatments
Gross and net amounts, recognition dates, allocations, refunds, taxes, and capitalisation rules must be applied consistently.
Assuming one universal target
A useful comparison depends on product type, network design, geography, supplier terms, service promise, seasonality, and measurement period; use like-for-like internal trends and clearly documented peer groups.
