Can I Afford to Give My Staff an Increment This Year? Here's How to Know

The annual increment conversation is one of the most stressful moments in any SME owner's calendar. Give too much and you squeeze your margins. Give too little and your best people start looking elsewhere. Get it wrong either way and you pay a price.

Most bosses make this decision based on how the year felt, what competitors are paying, and a general sense of whether they can "afford it." None of these are precise.

The Precise Answer

The Wage Affordability Index (WAI) gives you a precise answer. It measures what percentage of your total business wealth — operating profit plus labor cost — you retain after paying wages.

WAI = Operating Profit ÷ (Operating Profit + Total Labor Cost)

The target is 60%. At this level, you keep 60 cents of every dollar your business creates after wages — enough buffer to absorb cost increases, invest in the business, and weather a bad month.

When WAI is above 63%, you have a genuine buffer. This buffer tells you exactly how much you can increase your total wage bill before your financial cushion disappears.

The Increment Calculation

The available buffer formula is:

Buffer = ((0.40 × Operating Profit) − (0.60 × Labor Cost)) ÷ 0.60

If your buffer is $10,000 per month, you can increase your total wage bill by $10,000 per month before hitting the floor. For a team of 15 earning an average $5,000 each, a $10,000 buffer supports approximately a 13% increment across the team.

Critically, this buffer must cover all your wage increases — increment, new hires, and bonuses combined. If you give a 10% increment and hire one new person in the same cycle, you may be using 150% of your available buffer, permanently weakening your financial position.

The One Rule

Never give a permanent increment when your WAI is below 60%. At that point, you have no buffer — any increase pushes you further into unsustainable territory. Instead, use a one-off bonus, which costs the same this year but doesn't compound permanently.

This single rule, applied consistently, has saved more than a few Singapore SMEs from a payroll crisis.
