Cost Accounting nd (2 session) Prof. Amit De BASIC CONCEPT OF COST ACCOUNTING: Cost Accounting Cost Accounting and Financial Accounting DIFFERENT TYPES OF COST Direct cost Prime cost Indirect cost Fixed cost/Fixed overhead/Period cost Variable cost MATERIAL COSTING STOCK LEVELS ► Maximum stock level. Maximum level = Recording level + Recording quantity – Min. consumption = Recording level + Reordering quantity – { Min. consumption per period x Min. Recording period } ► Minimum stock level. Minimum Level = Reordering level – { Normal usage per period x Average delivery time } ► Re-order level. Re-order Level = maximum consumption during the period x Maximum period required for delivery. ► Danger level. ECONOMIC ORDER QUANTITY. EOQ Determination of EOQ by algebraic formula EOQ = 2 x Annual consumption x Cost of placing an order Cost of carrying one unit inventory for one year LABOUR COSTING Methods of Remuneration Time Rate System Payment by Result A. PIECE-RATE SCHEMES Straight piece work system. Wages = Number of units produced x piece rate per unit Differential Piece Work System. Taylor Differential rate System 80% of piece rate when below standard. 125% of piece rate when at or above standard. MERRICK DIFFERENTIAL OR MULTIPLE PIECE RATE SYSTEM ■ Up to 83-1/3% Normal piece rate applicable ■ Above 83-1/3% 10% above normal rate of efficiency but up to 100% ■ Above 100% 20% above normal rate PREMIUM BONUS PLANS Halsey Plan. Formula for Halsey Premium Plan under 50% Sharing Scheme Actual hrs. worked x Rate per hr. + 50/100 (Standard hrs. – Actual hrs.) x Rate per hour. Rowan Plan. Group Bonus System.
