How Do Cost-of-Living Adjustments Affect My Salary Abroad?

 Teaching abroad as an African educator opens doors to exciting experiences, professional growth, and often higher salaries than you might earn at home. However, when evaluating an international teaching contract, it’s essential to understand cost-of-living adjustments (COLAs) and how they impact your salary. While the base salary might look attractive, your actual purchasing power in a new country depends on many factors beyond the pay number.

In this blog, we’ll break down what COLAs are, why they matter, how schools apply them, and strategies for African teachers to maximize their financial well-being while working abroad.

What Is a Cost-of-Living Adjustment?

A cost-of-living adjustment (COLA) is a change made to your salary to reflect differences in expenses between your home country and your host country. It ensures that teachers maintain a comparable standard of living despite variations in housing, food, transportation, healthcare, and taxes.

For example:

• A teacher earning $2,000 per month in Nairobi may find that same salary insufficient in London due to higher housing and transportation costs.

• A COLA would adjust the salary upward to help maintain a similar lifestyle abroad.

Why Cost-of-Living Adjustments Are Important

1. Maintaining Purchasing Power

• The primary purpose of COLAs is to protect teachers from losing purchasing power when moving abroad.

• Without adjustments, a high nominal salary may not cover essential expenses in a more expensive city.

2. Ensuring Financial Stability

• Expat teachers often face unpredictable costs like international school fees for children, higher utility bills, or transportation costs.

• COLAs help stabilize finances so you can focus on teaching rather than struggling to cover basic expenses.

3. Reflecting Economic Differences

• COLAs account for inflation, exchange rates, and local economic conditions.

• This adjustment ensures your earnings remain fair compared to the cost of living in your host country.

How Schools Calculate Cost-of-Living Adjustments

Different schools and countries have varied methods for calculating COLAs:

1. Using International Cost-of-Living Indexes

• Many international schools reference indexes such as the Mercer Cost of Living Index or Numbeo to determine adjustments.

• These indexes compare the cost of housing, food, transportation, utilities, and other essentials between cities.

2. Standard Percentage Increases

• Some schools apply a flat percentage increase to your base salary based on your destination city.

• For example, teachers moving from Nairobi to London might receive a 40% salary increase to account for higher expenses.

3. Customized Adjustments

• Certain international schools personalize COLAs based on your personal situation, including family size, housing preferences, and school-provided benefits.

• Teachers with dependents may receive additional allowances to cover school fees, healthcare, and other family costs.

Common Components Affected by COLAs

When schools provide COLAs, they often adjust specific parts of your compensation package:

1. Housing Allowance

• Housing is typically the largest expense abroad.

• Schools may provide fully furnished housing, a housing stipend, or adjust your salary to cover rental costs.

2. Transportation Costs

• Urban areas may have higher public transport fees or fuel costs.

• COLAs may include allowances for commuting or provide a transportation stipend.

3. Food and Daily Living

• Grocery prices and dining expenses can vary widely.

• COLAs often account for local food costs to maintain comparable purchasing power.

4. Utilities and Healthcare

• Electricity, water, internet, and healthcare services can significantly differ between countries.

• Adjustments ensure teachers aren’t financially strained by essential services.

Real-Life Example: African Teachers Moving Abroad

Let’s say an African teacher earning $1,500 per month in Nairobi accepts a job in Paris, where the cost of living is substantially higher. Without a COLA:

• Housing may consume 50–60% of their salary.

• Groceries, transportation, and healthcare may cost twice as much as back home.

• Their take-home pay might not cover basic living expenses, despite a higher nominal salary.

With a COLA:

• The school increases the salary by 30–40% or provides housing and transport allowances.

• The teacher can maintain a similar standard of living as in Nairobi.

• Financial stress is reduced, allowing the teacher to focus on teaching.

Tips for African Teachers Negotiating COLAs

1. Research the Cost of Living in Your Host City

   • Compare housing, transportation, food, and healthcare costs to your current location.

   • Online cost-of-living calculators like Numbeo or Expatistan can be helpful.

2. Understand the Components of Your Salary Package

   • Separate base salary, housing, transportation, and allowances to understand total compensation.

3. Negotiate Additional Allowances if Needed

   • Don’t hesitate to ask for extra support for school fees, healthcare, or relocation costs.

4. Consider Currency Fluctuations

   • Exchange rates can affect purchasing power if you plan to send money home.

   • Some schools offer salary adjustments for major currency fluctuations.

5. Factor in Taxes

   • Some countries impose higher taxes on expatriate teachers.

   • Ensure the COLA covers the impact of income tax on your net salary.

Limitations of COLAs

While COLAs help maintain living standards, there are limitations:

• Not Always Comprehensive – Some schools provide flat percentage increases without considering family needs or unique lifestyle costs.

• Temporary Adjustments – COLAs may be reviewed annually, so unexpected inflation could erode purchasing power between adjustments.

• Exchange Rate Risks – Teachers sending money home may still face losses if local currency weakens.

African teachers should plan for these risks and budget carefully to avoid financial surprises.

Maximizing the Benefit of COLAs

1. Track Your Expenses

   • Keep a detailed record of monthly expenses abroad to evaluate if the COLA meets your needs.

2. Combine COLAs with Smart Financial Planning

   • Use savings, investments, and efficient banking solutions to maximize income.

3. Seek Advice from Other Expat Teachers

   • Join expatriate networks or online communities to learn about real costs and COLA effectiveness.

4. Review Contracts Carefully

   • Ensure the COLA is clearly stated in your employment contract, including details about housing, transportation, and family allowances.
