Lesson Content/Board Summary
DOCUMENTS USED IN PREPARING SALARIES AND WAGES
Introduction to Salaries and Wages
Salaries and wages are payments made to employees for their work. Salaries are typically fixed payments for professional or managerial work, usually paid monthly, while wages are often hourly or daily payments for manual or casual labour.
Key Documents for Salaries and Wages
The following are important documents used in preparing and managing salaries and wages:
- Payroll: This is a list of all employees in an organisation, showing their basic salaries, allowances, deductions, gross pay, and net pay for a specific period (e.g., a month). It serves as a record of payments made.
- Pay Slip: A pay slip (or payslip) is a document issued to an employee, detailing their earnings, deductions, and net pay for a specific pay period. It provides a transparent breakdown of how an employee’s salary is calculated.
- Payment Voucher: A payment voucher is an internal document used to authorise and record payments. For salaries and wages, it documents the approval for the total amount to be paid out to employees from the company’s accounts.
Calculation of Gross Pay
Gross pay is the total amount an employee earns before any deductions are made. It includes the basic salary and all allowances.
Formula: Gross Pay = Basic Salary + Total Allowances
Allowances can include: Housing Allowance, Transport Allowance, Meal Allowance, Utility Allowance, etc.
Example 1: Calculation of Gross Pay
Mr. Adamu earns a Basic Salary of N80,000.00. He also receives a Housing Allowance of N15,000.00 and a Transport Allowance of N10,000.00 per month.
Step 1: Identify Basic Salary and Allowances.
Basic Salary = N80,000.00
Housing Allowance = N15,000.00
Transport Allowance = N10,000.00
Step 2: Add all allowances to the basic salary.
Gross Pay = N80,000 + N15,000 + N10,000
Step 3: Calculate the total.
Gross Pay = N105,000.00
Calculation of Net Pay
Net pay (or take-home pay) is the amount an employee receives after all deductions have been made from their gross pay.
Formula: Net Pay = Gross Pay – Total Deductions
Deductions can include: Pay As You Earn (PAYE) Tax, Pension Contributions, National Health Insurance Scheme (NHIS), Union Dues, Loan Repayments, etc.
Example 2: Calculation of Net Pay
Using Mr. Adamu’s Gross Pay from Example 1 (N105,000.00), calculate his Net Pay if his deductions are: PAYE Tax N8,000.00, Pension Contribution N5,000.00, and Union Dues N1,000.00.
Step 1: Identify Gross Pay and Deductions.
Gross Pay = N105,000.00
PAYE Tax = N8,000.00
Pension Contribution = N5,000.00
Union Dues = N1,000.00
Step 2: Calculate Total Deductions.
Total Deductions = N8,000 + N5,000 + N1,000 = N14,000.00
Step 3: Subtract Total Deductions from Gross Pay.
Net Pay = N105,000 – N14,000
Step 4: Calculate the Net Pay.
Net Pay = N91,000.00
Preparation of a Pay Slip
A pay slip typically includes the following information:
- Employee’s Name and ID
- Company Name
- Pay Period (e.g., Month, Year)
- Basic Salary
- List of Allowances (e.g., Housing, Transport)
- Gross Pay
- List of Deductions (e.g., PAYE, Pension, NHIS)
- Net Pay
- Date of Payment

Lesson Keywords
- Payroll – A list of employees showing their earnings and deductions.
- Pay Slip – A document detailing an employee’s earnings and deductions for a pay period.
- Payment Voucher – An internal document authorising a payment.
- Gross Pay – Total earnings before deductions.
- Net Pay – Earnings after all deductions.
- Allowances – Additional payments to employees (e.g., housing, transport).

Differentiation
For pupils who grasp concepts quickly, the teacher can provide more complex scenarios for calculating gross and net pay, involving multiple types of allowances and deductions. For those who need more support, the teacher will provide simplified examples and one-on-one guidance, focusing on understanding the basic definitions and simpler calculations.
Note for teachers using this lesson plan
Ensure you have clear, large specimens of payrolls, pay slips, and payment vouchers. Encourage pupils to bring sample pay slips from their guardians (with sensitive information redacted) to make the lesson more relatable. Emphasize the importance of accuracy in all calculations to avoid errors in salary payments.
