What is a Manpower Rate Calculation?
Manpower rate calculation is the process of determining the actual cost and billable value of an employee's time. It goes far beyond just the basic salary. For a business to remain profitable and cover all operational costs, it must account for employer-paid taxes, insurance, office overheads, and a sustainable profit margin when quoting services to clients.
Key Components of the Manpower Rate
To accurately calculate a manpower rate, you must consider three primary layers:
- Direct Costs: This includes the basic salary and fixed monthly allowances like transport, housing, or health insurance.
- Statutory Burdens: These are employer-side contributions such as Social Security, Pension funds, and payroll taxes.
- Indirect Costs (Overhead): This covers the cost of "keeping the lights on"—office rent, electricity, administrative staff, and equipment.
- Profit Margin: The additional percentage added to ensure the business grows and generates a return on investment.
How to Calculate Manpower Hourly Rate
The formula used by this calculator follows a professional accounting sequence:
1. Direct Cost = (Basic Salary + Allowances) * (1 + Tax Percentage)
2. Gross Cost = Direct Cost * (1 + Overhead Percentage)
3. Billable Monthly = Gross Cost * (1 + Profit Percentage)
4. Hourly Rate = Billable Monthly / (Working Days × Working Hours)
Calculation Example
Suppose an engineer has a basic salary of 4,000 with 500 in allowances. The employer pays 10% in social taxes, has a 20% overhead cost, and wants a 10% profit. The staff works 22 days a month, 8 hours a day.
- Total Direct Cost: (4,000 + 500) + 10% = 4,950
- With Overhead: 4,950 + 20% = 5,940
- With Profit (Billable): 5,940 + 10% = 6,534
- Daily Rate: 6,534 / 22 = 297.00
- Hourly Rate: 297 / 8 = 37.13
By using this structured approach, project managers can ensure that every hour of labor sold contributes positively to the company's financial health.
function calculateManpower() {
// Get input values

// Calculation Logic
var totalDirectSalary = basic + allowances;
var costWithTaxes = totalDirectSalary * (1 + (taxesPct / 100));
var costWithOverhead = costWithTaxes * (1 + (overheadPct / 100));
var finalBillableMonthly = costWithOverhead * (1 + (profitPct / 100));
var dailyRate = finalBillableMonthly / days;
var hourlyRate = dailyRate / hours;
