| Type | Initialism |
The initialism SOB stands for Share of Business in the cited supplier terminology. NBC Bearings’ Supplier Quality Manual 2023 explicitly lists this expansion. The initials alone do not specify the measure, denominator or period behind a particular share.
A percentage is useful only when its part and whole are defined. A share of purchased units, a share of spend and a share of supplier count answer different questions. For an original fictional example, 30 units supplied out of 120 eligible units gives 25% of those units. That does not establish 25% of the buyer’s spend, every product, another reporting period or the global market. Keep the buyer or business scope, measure, unit and period with both numbers, and confirm that the numerator is included in the stated denominator. If the part is larger than the whole, review the definitions rather than treating it as an ordinary part-of-whole share. The calculator accepts non-negative decimal values, a positive total and an explicitly declared common basis. It uses exact decimal arithmetic and rounds the percentage to at most three decimal places when needed. The naming source establishes the expansion; it does not prescribe this worksheet, a universal procurement formula or an entitlement to future orders. Use the tool to explain your supplied ratio, not to verify a contract or infer an allocation that the record does not give.

Meaning in context
- Share of Business
- The expansion explicitly listed in the cited supplier-manual abbreviation table.
- Part and whole
- The calculator’s declared ratio compares one supplied part with a total that includes it; the labels determine what the result means.
Practical examples
Keep a unit share labelled as units
- Before
Invented same-scope record: a supplier provides 30 of 120 eligible units. Draft: The supplier necessarily receives 25% of all buyer spending.
- After
The fictional supplier provides 25% of the stated 120 units; its spend share is not supplied.
The computed ratio is 30 ÷ 120 × 100 = 25%. Changing its measure to spend would require different evidence.
Do not mix a count and a volume share
- Before
Invented records: one of four suppliers provides 90 of 100 eligible units. Draft: Its unit share must equal its 25% share of supplier count.
- After
The fictional supplier is 25% of the supplier count and supplies 90% of the stated units.
Supplier count and supplied volume have different denominators and need not produce the same percentage.

Calculate a declared business share
What does this SOB percentage measure, and which total is its denominator?
See all guidance
Define the denominator
State what belongs in the total and which period it covers.
The fictional total is 120 eligible units for the named buyer and period.
Calculate a share
Use the same measure and unit for the supplied part and whole.
Thirty of 120 units gives a 25% unit share.
Read an allocation claim
Distinguish an observed share, an intended allocation and a contract.
The supplied observation gives no entitlement to future orders.
Define the same measure, unit, scope and period for part and total before calculating a part-of-whole share.
