Imagine you're running a factory in Pune. You need to pay your workers — but how you pay them changes everything: their motivation, your costs, and your profits. That's what Methods of Wage Payment is about. The ICAI exam loves this topic because it combines theory and calculation in one.
The two root methods are Time Rate and Piece Rate. Under Time Rate, Ramesh gets ₹200/hour regardless of how many units he makes — stable income, zero production pressure. Under Piece Rate, Suresh gets ₹5/unit — make more, earn more. Simple, but risky for the worker (machine breakdown = zero pay). Most real factories blend both ideas through Incentive / Premium Plans.
The three plans you must master for the exam:
Halsey Premium Plan — Worker gets Time Rate wages for actual hours worked, plus 50% of the wages for time saved. The formula: Earnings = (Actual Hours × Rate) + 50% × (Time Saved × Rate). The employer pockets the other 50% as a cost saving. Sharing is always 50:50 unless stated otherwise.
Rowan Premium Plan — Similar base, but the bonus fraction changes with efficiency. Bonus = (Time Saved ÷ Standard Time) × Actual Hours × Rate. The key quirk: the bonus never exceeds the basic time-rate wages, making it safer for employers when workers are very fast.
Taylor's Differential Piece Rate — No time rate at all. Two rates exist: workers producing below standard get 83⅓% of the piece rate; workers at or above standard get 125% of the piece rate. It's a harsh system — low performers are penalised sharply. Merrick's Multiple Piece Rate softens this into three slabs: up to 83% of standard → 100% rate; 83–100% → 110% rate; above 100% → 120% rate.
Exam tip: Gantt Task & Bonus Plan combines time rate (for below-standard output) with a bonus of 20% above time rate (at standard) and piece rate above standard — it appears occasionally as a 4-mark question, so know the three tiers.
Always check: what is the standard time / standard output in the question — that's your anchor for every calculation.
