Why 63% of Singapore SMEs Are Paying Wages They Cannot Sustain

The Singapore Business Federation's 2024/25 survey is blunt: manpower costs are the number one challenge for Singapore businesses, cited by 63% of firms. Yet most of those same firms cannot tell you in precise numbers whether their wage bill is sustainable.

They feel it. They worry about it every payroll cycle. But they don't have a system for measuring it.

The Wage Sustainability Problem

Wage sustainability is not simply about whether you can make payroll this month. A business can make payroll while slowly destroying its financial health — by generating too little profit relative to what it spends on people.

The Wage Sustainability Index (WSI) measures this precisely:

WSI = Operating Profit ÷ Total Labor Cost

A WSI of 1.5 means for every $1 you spend on wages, you generate $1.50 in operating profit. At this level, your wage bill is genuinely sustainable — you have buffer for increments, for a bad month, for unexpected costs.

A WSI below 1.0 means wages are consuming more than your profit can support. You are running to stand still.

What Sustainable Headcount Looks Like

The WSI also tells you how many staff your profit can sustainably support. If your operating profit is $105,000 per month and your average salary is $5,000, your sustainable headcount range is approximately 13–16 staff. Below that range, you have capacity to grow. Above it, you are carrying more people than your earnings can support.

Most SME bosses discover — when they run this calculation for the first time — that they are over their sustainable range. Not by much, but enough to create permanent financial pressure that compounds every year.

The Government's Response

Singapore's government has recognised this problem. The Progressive Wage Model, SkillsFuture credits, and various productivity grants are all attempts to help SMEs either increase the output per employee (raising the WSI numerator) or reduce the cost of certain roles (lowering the denominator).

But grants come and go. The fundamental equation remains: are your people generating enough profit to justify what they cost?

The One Number to Track

If you track nothing else about your manpower costs, track your WSI monthly. Trending upward means your business is becoming more efficient at converting people investment into profit. Trending downward is an early warning that should trigger a review before the situation becomes critical.
