If Your Income Hasn't Grown by This Amount in 2026, You're Poorer Than You Think

Most people assume that if their salary has increased over the past year, they are automatically better off financially.

Unfortunately, that is not always the case.

A salary increase only improves your financial position if it grows faster than the forces that quietly reduce your purchasing power. Rising prices, changes in taxes and statutory deductions, and movements in exchange rates all chip away at the value of your income over time.

This is where the concept of a salary hurdle rate comes in.

Think of it as the minimum percentage your salary needs to increase each year just to maintain the same standard of living. If your income grows below this rate, you may actually be getting poorer, even though you're earning more money.

Here's how it works using the example of someone who earned a net salary of Ksh100,000 in June 2025.

Inflation: The Biggest Erosion of Your Income

According to government data, inflation averaged 6.4% over the past year. Inflation measures how quickly the prices of goods and services increase.

If inflation averages 6.4%, it means the same basket of goods that cost Ksh100,000 a year ago would now cost approximately Ksh106,400.

In other words, your salary would need to increase by at least 6.4% simply to maintain the same purchasing power.

For many households, however, the real cost-of-living increase has felt even higher.

Exchange Rate Movements Also Matter

Although you may not earn your salary in foreign currency, exchange rates still affect your daily expenses.

Kenya imports fuel, machinery, electronics, pharmaceuticals and many other products. When the shilling weakens against major trading currencies, import costs often rise, eventually pushing up local prices.

Over the past year, the Kenya shilling remained largely stable against the US dollar, depreciating by only 0.2% since June 2025.

However, it weakened against some of Kenya's other major trading currencies, including the euro and the Tanzanian shilling, while strengthening against others.

Taking these movements into account, the overall impact on purchasing power can reasonably be estimated at around 0.7%.

Higher NSSF Deductions Reduced Take-Home Pay

The third factor affecting workers' incomes came through statutory deductions.

In February 2026, the implementation of the National Social Security Fund (NSSF) Act entered another phase, increasing mandatory contributions for employees earning above Ksh75,000.

Depending on income levels, the increase ranged from Ksh126 to as much as Ksh2,160 per month.

For an employee earning Ksh100,000, monthly NSSF contributions increased from Ksh4,320 to Ksh6,000.

That represents an additional deduction equivalent to approximately 1.68% of gross salary.

Although NSSF contributions remain tax-deductible, the higher deductions still reduce monthly disposable income available for everyday expenses.

The Salary Hurdle Rate

When these three factors are combined, they produce what can be considered your salary hurdle rate.

• Inflation: 6.4%
• Exchange rate impact: 0.7%
• Higher NSSF deductions: 1.68%

Together, this comes to approximately 8.8%.

This means that someone earning Ksh100,000 in June 2025 would need to earn roughly Ksh108,800 today simply to maintain the same purchasing power.

Any salary increase below that level means your income has grown in nominal terms, but your ability to buy goods and services has actually declined.

How to Protect Your Purchasing Power

While workers have limited control over inflation or statutory deductions, there are practical ways to reduce their impact.

The first is to understand your own hurdle rate. Rather than focusing only on whether your salary has increased, compare the increase with changes in the cost of living and deductions. This gives a clearer picture of whether you are genuinely making financial progress.

Secondly, diversify your income. Depending entirely on annual salary increments can make it difficult to keep pace with rising living costs. Additional income streams from investments, side businesses, dividends or rental income can help bridge the gap.

It is also important to make full use of available tax reliefs. While deductions such as SHIF and the Affordable Housing Levy remained unchanged during the review period, workers can still maximise available pension and tax reliefs to reduce their overall tax burden.

Finally, keep an eye on tax policy changes. The National Treasury has proposed reducing PAYE for some tax bands, a move that could increase take-home pay for many workers if implemented.
