The amount of adjustment of the delivery location and grade of deliverables that a futures contract permits. Also known as "allowance. "

Investopedia Says:
Some futures contracts allow the short position to adjust the location of the delivery and/or the grade of commodity being delivered. The permitted differentials are set in relation to a central location or the par basis grade.

1. Banking. Refers to the 1⁄4 of 1% difference between deposit interest rates paid by commercial banks and rates paid by savings and loans. The rate differential on time deposit accounts, created in the 1960s to give thrift institutions a stable funding source for mortgage lending, was phased out in January 1984.

2. Finance. A broker's commission for handling small, odd-lot orders, which normally is higher than with regular orders.

• d. absorption — see differential absorption.
• d. cell count — see differential count.
• d. diagnosis — the differences between diseases in terms of clinical signs and epidemiological parameters; used as a basis for selecting as a diagnosis the one with the best fit to those seen in the subject.
• d. leukocyte count — see differential count.
• d. milk cell counts — count of cells in a milk sample including individual counts of somatic cells and individual leukocyte types.
• d. thromboplastin time — used in differentiating the cause of hemophilia. Reagents containing either factor VIII or factor IX are added in the partial thromboplastin time test to demonstrate which factor corrects the prolonged clotting time.

Tutor's tip: The "differential" (the amount of difference) in their test scores was small, but the loser was "deferential" (marked by courteous yielding or respect) to the winner anyway.

Medicine

• Differential diagnosis refers to the characterization of the underlying cause of pathological states based on specific tests.

• Differential WBC count is the enumeration of each type of white blood cells either manually or using automated analyzers.

Mathematics

• Differential (mathematics) comprises multiple related meanings of the word, both in calculus and differential geometry, such as an infinitesimal change in the value of a function

• In calculus, the differential represents a change in the linearization of a function.
• In traditional approaches to calculus, the differentials (e.g. dx, dy, dt etc...) are interpreted as infinitesimals. Although infinitesimals are difficult to give a precise definition, there are several ways to make sense of them rigorously.
• In multivariable calculus and differential topology, the differential of a smooth map between Euclidean spaces or differentiable manifolds is the approximating linear map between the tangent spaces, called pushforward (differential)
• In differential geometry, exterior differential, or exterior derivative, is a generalization to differential forms of the notion of differential of a function on a differentiable manifold

• Differential (coboundary), in homological algebra and algebraic topology, one of the maps of a cochain complex
• Differential (cryptography), in differential cryptanalysis, a pair consisting of the difference, usually computed by XOR (exclusive or), between two plaintexts, and the difference of the corresponding ciphertexts

See also derivative, differential calculus.

Natural sciences and engineering

• Differential (mechanical device). As part of a powertrain, the device that allows each of the driving wheels to rotate at different speeds.
• Electronic Differential, an electric motor controller which substitutes its mechanical counterpart with significant advantages in electric vehicle application.
• In electronics, differential signaling applies to a method of transmitting electronic signals over a pair of wires to improve noise immunity.

Social sciences

• Semantic and structural differentials in psychology
• A quality spread differential in finance
• Compensating differential in labor economics

Other uses

The word differential is also used in many fields as an adjective to refer to differences, particularly those of a variable or continuous nature. Examples include differential hardening in metallurgy, differential rotation in astronomy, differential centrifugation in cell biology, differential scanning calorimetry in materials science, differential signalling in communications, differential algebra in mathematics, differential execution in computer science, and differential GPS technology.
