Difference between differential costing and marginal costing

Differential Costing and Marginal Costing are related concepts in cost accounting, but they have distinct characteristics.

Differential Costing:

  1. Focus:
  • Differential costing compares the total costs between alternative courses of action.
  • It considers the overall impact on costs when choosing one option over another.
  1. Scope:
  • It encompasses all relevant costs, both variable and fixed, associated with different alternatives.
  • This approach analyzes the total impact on profit or cost when a change occurs.
  1. Decision-Making:
  • Differential costing is particularly useful in decision-making scenarios where management needs to choose between alternatives.
  • It helps in assessing the financial implications of different decisions on the overall cost structure.

Marginal Costing:

  1. Focus:
  • Marginal costing concentrates on the behavior of costs in relation to changes in production volume or output.
  • It specifically deals with variable costs and their contribution to covering fixed costs.
  1. Scope:
  • It mainly considers variable costs, separating them from fixed costs to calculate the contribution margin.
  • Fixed costs are treated as period costs and are not allocated to products based on production volume.
  1. Decision-Making:
  • Marginal costing is often used for short-term decision-making, such as determining the profitability of producing additional units.
  • It provides insights into the contribution of each additional unit to cover fixed costs and make a positive contribution to profit.

Key difference between differential costing and marginal costing

  • Focus on Alternatives:
  • Differential costing focuses on comparing the total costs of different alternatives.
  • Marginal costing emphasizes the behavior of costs concerning changes in production volume.
  • Cost Components:
  • Differential costing considers all relevant costs, both variable and fixed.
  • Marginal costing primarily considers variable costs and treats fixed costs as period costs.
  • Decision Context:
  • Differential costing is often applied when making strategic decisions between different courses of action.
  • Marginal costing is commonly used for short-term operational decisions related to production levels.

In summary, while both concepts play a role in managerial decision-making, differential costing is more comprehensive, considering all costs associated with alternatives, whereas marginal costing specifically focuses on variable costs and their contribution to covering fixed costs.

The time taken to return to the point of projection is: (A) 3 s (B) 4 s (C) 5 s (D) 6 s Show Answer Answer: (D) Total time = 2u/g = 2×30/10 = 6 s. Q2. (Chemistry) Which species has the maximum number of unpaired electrons? (A) Fe²⁺ (B) Fe³⁺ (C) Mn²⁺ (D) Cu²⁺ Show Answer Answer: (C) Mn²⁺ = 3d⁵ configuration → maximum unpaired electrons. Q3. (Mathematics) If sin θ = 3/5 and θ lies in first quadrant, then cos θ is: (A) 4/5 (B) 3/4 (C) 5/4 (D) 2/5 Show Answer Answer: (A) cos²θ = 1 − sin²θ = 1 − 9/25 = 16/25 ⇒ cos θ = 4/5. Q4. (Biology) The functional unit of kidney is: (A) Neuron (B) Alveoli (C) Nephron (D) Glomerulus Show Answer Answer: (C) Nephron is the structural and functional unit of kidney. Q5.

IAT Mock Test 2026 – Part 1 Marking Scheme: +4 Correct | -1 Incorrect | 0 Unattempted Q1. A particle moves in a straight line such that its displacement is given by x = t³ − 6t² + 9t + 4. At what time is its velocity zero? (A) 1 s (B) 2 s (C) 3 s (D) Both A and C Show Answer Correct Answer: (D) v = dx/dt = 3t² − 12t + 9 = 3(t−1)(t−3). Therefore velocity is zero at t = 1 s and 3 s. Q2. The number of stereoisomers possible for a compound with two chiral centers is: (A) 2 (B) 4 (C) 6 (D) 8 Show Answer Correct Answer: (B) Maximum stereoisomers = 2ⁿ, where n = number of chiral centers. Hence 2² = 4. Q3. If z = 1 + i√3, then the principal argument of z is: (A) π/6 (B) π/3 (C) π/2 (D) 2π/3 Show Answer Correct Answer: (B) tan θ = √3/1 = √3, first quadrant ⇒ θ = π/3. Q4.

The magnitudes of power of a biconvex lens (refractive index 1.5) and a plano-concave lens (refractive index 1.7) are equal. If the curvature of the concave surface of the plano-concave lens exactly matches the curvature of the back surface of the biconvex lens, find the ratio of radii of curvature of the front and back surfaces of the biconvex lens
