Adding one full-time employee is among the biggest financial decisions a small company makes. Salary is a fixed cost you pay every month whatever sales do. A new hire needs months to reach full output. And if the hire does not work out, letting someone go has a legal cost. So many companies hire too late and burn out the team, or hire too early and run out of cash before the new person delivers.

This article offers a numbers-based way to decide: what one employee really costs, the signals that it is time to hire, how to work out when a new hire pays back, and the alternatives to consider before adding permanent headcount.

An Employee Costs More Than a Salary

The fully loaded cost to the employer includes several items that often get left out of the budget:

  • Employer social security contributions. The standard rate is 5% of wages. From January 1, 2026, the wage base runs from a minimum of 1,650 baht to a maximum of 17,500 baht a month, so the employer's share is at most 875 baht per person per month. The employer remits it, together with the amount withheld from the employee, by the 15th of the following month.
  • Workmen's Compensation Fund contributions. Paid by the employer alone, at 0.2–1.0% depending on the risk of the business type, on wages of up to 240,000 baht per person per year.
  • Bonuses and benefits, such as group health insurance, travel and meal allowances.
  • Equipment and software: a computer and per-user subscriptions.
  • Recruiting costs: job ads, agency fees and the management time spent interviewing and training.
First-year cost of an employee on a 35,000 baht monthly salary (illustrative example)
Item Baht per year
Salary, 12 months 420,000
Employer social security, 875 × 12 10,500
Workmen's Compensation Fund, 0.2% × 240,000 480
Bonus, one month 35,000
Group health insurance 12,000
Computer 30,000 and software 10,000 40,000
Recruiting agency fee, one month's salary 35,000
First-year total 552,980

In this example the first-year cost is about 1.32 times the annual salary. Every company's figure differs with its benefits and hiring channels, but you should know your own before you post the job.

Signals That It Is Time to Hire

"We're busy" is not enough. Look for measurable evidence that repeats for at least two to three months, not a single peak.

  • You turn down or delay customer work. Count the sales or gross profit lost each month. That number is the minimum benefit of hiring.
  • Turnaround or quality slips: slower replies to customers, more rework, more complaints.
  • The team works overtime as a matter of routine. Monthly overtime pay may already be close to the cost of a new hire, and a team that stays exhausted is at risk of quitting.
  • Founders spend most of their time on work someone else could do, such as paperwork, collections or routine questions, instead of finding customers or planning.

If the signal comes from one-off work, such as a large project that ends in three months, the temporary options below are usually a better fit.

When Will the New Hire Pay Back?

For revenue roles such as sales, compare the gross profit the person will generate with their cost. For support roles such as accounting or admin, count the work you get back: time freed for others to generate revenue, or overtime and outside fees that go away.

What people often forget is the ramp-up period. New hires do not deliver full output in month one.

Illustrative example: hiring one salesperson

  • Upfront cost of 65,000 baht (35,000 agency fee and a 30,000 computer).
  • Monthly cost of 40,665 baht (35,000 salary, 875 social security, 40 workmen's compensation, plus 4,750 set aside for bonus, health insurance and software).
  • At full productivity, 80,000 baht of gross profit a month.
  • No results in months 1–3, then 25% of target in month 4, 50% in month 5, 75% in month 6 and full target from month 7.

Hire payback = the first month in which cumulative gross profit from the hire ≥ cumulative cost of the hire

Cumulative cost and gross profit (baht, illustrative example)
End of month Cumulative cost Cumulative gross profit Difference
3 186,995 0 −186,995
5 268,325 60,000 −208,325
8 390,320 280,000 −110,320
11 512,315 520,000 7,685
12 552,980 600,000 47,020
Line chart of cumulative cost and cumulative gross profit from a new salesperson over 18 months; cumulative gross profit passes cumulative cost in month 11 and reaches 1,080,000 baht by month 18 against 796,970 baht of cost
The hire pays back in month 11, but until then the company needs cash to cover a shortfall that peaks at about 208,000 baht in month 5.

Two numbers from the table drive the decision:

  1. Payback in month 11. If you are not confident you can keep this person for more than a year, or customer demand could fade before then, a permanent hire does not yet pay.
  2. About 208,000 baht of cash to set aside. This is the largest shortfall before the hire delivers, and it must come on top of the company's normal cash reserve.

Test how sensitive the result is. If ramp-up takes two months longer, or the person reaches only 70% of target, how far does payback move? If it moves beyond the time your cash can cover, wait or start with an alternative.

Alternatives to a Permanent Hire

  • Part-time staff or short fixed-term contracts suit work that has grown for a period or may not last.
  • Outsourcing suits work outside the core of the business, such as bookkeeping, payroll or IT. The cost is variable and can stop under the contract terms.
  • Freelancers suit project work. Be careful: if a contractor works under your direction like a regular employee, the relationship may be treated as employment. Have a legal adviser review the contract.
  • Process changes and tools. Repetitive daily work, such as invoicing or answering common questions, can often shrink with software you already pay for.

The Cost If a Hire Does Not Work Out

Under Section 118 of the Labour Protection Act, an employee dismissed without serious misconduct is entitled to severance pay based on length of service.

Severance pay under Section 118 of the Labour Protection Act
Length of service Severance (days of final wage)
120 days to under 1 year 30 days
1 year to under 3 years 90 days
3 years to under 6 years 180 days
6 years to under 10 years 240 days
10 years to under 20 years 300 days
20 years or more 400 days

Severance is separate from pay in lieu of notice. Setting clear goals from day one and reviewing performance seriously at intervals during probation is fair to both the company and the employee. If a dismissal becomes necessary, get advice from a labor lawyer first.

Where to Start

  1. Work out your fully loaded cost per employee with a table like the one above: social security, workmen's compensation, bonus, benefits, equipment and recruiting.
  2. Collect two to three months of evidence: work turned down, overtime, turnaround times and founder hours spent on work others could do.
  3. Write down the expected output of the role in numbers, along with ramp-up assumptions, then calculate payback and the cash you need to set aside.
  4. Put the hire into your cash flow forecast and see how long your cash lasts afterward. If it is not enough, start with a temporary option.
  5. Review at three and six months. Compare actual results with your assumptions. If they beat the plan, it may be time to plan the next hire. If they lag, find out why before hiring more.
