How to Do Payroll by Hand
Your employees must get paid for the work they do. Simple as that. Handling payroll differs from company to company, but there are many well-recognized calculation methods. For some small businesses, doing manual calculations is the only option.
Manually calculating an employee’s paycheck is based on whether he or she is salaried or hourly. To determine an hourly employees’ pay by hand, you must examine their time-sheets or punches for a week, or two weeks. To calculate a salaried employees’ pay, you can use an annual salary calculation.
Weekly Calculation
Let’s say your full-time hourly employee, Glenn, makes $15 an hour. You pay him bi-weekly. To measure his pay, your calculation should look like this:
40 hours x 2 = 80 hours. 80 x $15/hour = $1,200. This is his gross pay.
Full-time hourly employees who work more than 40 hours a week must earn overtime. Overtime in the U.S. is equal to one and half times an employee’s regular rate of pay. If Glenn works 50 (or ten extra hours both weeks) hours each week, instead of 40, this is what your calculation should look like:
Pay his regular rate from above, then determine overtime. 10 x 2 = 20 hours. 20 x $22.5/hour (15 x 1.5) = $450. This is also gross pay, albeit overtime
Annual Calculation
Your full-time salaried employee Linda makes $56,000 annually. You pay her semi-monthly (24 pay periods in a year). Determining her pay is a simple calculation, based on your company’s pay schedule. It should look like this:
$56,000 / 24 = $2,333.33. This is her gross pay.
Net Pay
The above scenarios only measure an employee’s gross pay. Once you withhold the proper federal, state, and local taxes, you’ll end up with employees’ net pay. For 2019, an employee’s withholding taxes are:
-A 6.2% Social Security tax on the first $128,700 of wages
-A 1.45% Medicare tax on the first $200,000 of wages
-A 2.35% Medicare tax above $200,000+

How to calculate payroll
The calculation of payroll involves the determination of gross pay, followed by the subtraction of deductions and payroll taxes to arrive at net pay. The calculation of payroll is a highly regimented process. This calculation should be followed meticulously, to ensure that there are no mistakes in the amount of net pay issued to employees, or taxes paid to the government. The calculation steps for payroll are as follows:
- Notify employees. Tell employees to complete their timesheets by the close of business on the last day of the payroll period. Otherwise, pursuing employees to complete their timesheets will delay the payroll.
- Collect timesheets. Obtain timesheets from all employees. This information may be located in an on-line timekeeping system.
- Review and approve timesheets. Review all timesheets for completeness, and then forward them to the relevant supervisors for approval. Overtime in particular should be approved, since it is 50% more expensive than regular pay.
- Enter hours worked. Enter this information if the hours worked information is collected manually. Otherwise, it may already be in the system.
- Enter wage rate changes. Enter all authorized changes into the payroll system for wage rate alterations, withholdings, and deductions. In particular, ensure that all deductions have been entered for adjustments to gross wages for tax purposes, since they impact the amount of payroll taxes paid.
- Calculate gross pay. Multiply wage rates by the number of hours worked to arrive at gross pay.
- Calculate net pay. Deduct all authorized withholdings and pay deductions from gross pay to arrive at net pay.
- Review. Print a preliminary payroll register and examine the gross pay, deductions, and net pay for each employee, to ensure that it is correct. If it is not correct, revise the prior entries and run another preliminary payroll register.
- Pay employees. Cut paychecks and remittance advices. Also print a final payroll register and archive it. Have an authorized person sign the checks. Alternatively, issue electronic payments to employees.
- Remit taxes. Forward all applicable payroll taxes to the government by the mandated due date.
- Distribute pay. If checks were cut, retain them in the company safe and distribute them on pay day. An extra control is to require a proof of identification before handing a check to an employee.
Paperless Payroll
As you can see manual payroll calculations are quite labor-intensive. To reduce time and risk for error, you can simplify the process by switching to a paperless payroll. The benefits of going paperless include:
Electronic quarterly payroll tax returns.Quick access to real-time payroll data for proper payroll processing.Employees have self-service option to manage payment preferences and view pay statements.Customizable security levels to protect data.Custom reporting capabilities.Complete integration with benefits administration and other voluntary deductions.
The math involved in manual payroll calculations is extremely time-intensive. It requires constant attention and also increases the risk for errors and late payments to government agencies. Adopting a paperless payroll process will make payroll easier, freeing up time and providing self-service options for employees when they need information.

Calculate Tax Withholding
Step 1
Calculate each employee’s tax withholding individually. Review the employee’s W-4 form to identify the number of allowances claimed. Identify the current deduction amount per allowance as defined by the Internal Revenue Service each year. Multiply the number of allowances by the exemption amount. For example, in 2012, the exemption amount equals $73.08 per allowance for weekly payroll processing. If the employee claims 2, deduct $146.16 from the employee’s gross pay.
Step 2
Refer to the current IRS withholding chart for the current tax year to determine the employee’s withholding amount. Find the appropriate payroll cycle and marital status on the chart, and identify the withholding amount based on the employee’s taxable income. The pay frequency may be weekly, bi-weekly, semi-monthly or monthly. As an example, an employee with $310 in taxable earnings for a week in 2012 would have 10 percent tax withheld on all earnings exceeding $156, or $15.40.
Step 3
Calculate the Social Security and Medicare withholding for the pay period. Check the current tax rates according to the Internal Revenue Service tax publication for the year. In 2012, the Social Security withholding equals 4.2 percent of all earnings up to $110,000. The Medicare percentage for 2012 is 1.45 percent of all earnings. Reduce the employee’s net pay by the tax withholding calculations.
Step 4
Calculate and deduct any other employee contributions such as health insurance premiums, 401(k) contributions or other deductions
