Keeping Your Impact Timely: How to Update MeasureUp Values for Inflation 

Understanding how to adjust MeasureUp values for inflation is important for making sure your social impact assessments reflect the real world. This guide explains why we update these values and how you can ensure your project evaluations stay accurate. 

The latest MeasureUp values, currently set to 2025 prices, are available to download at the top of our MeasureUp Values page. We update these numbers every year using confirmed, official inflation data from the previous year rather than relying on estimates or future predictions. 

Please note: The monetised social value figures showing on each value’s page will stay at the year of it’s original publication on the MeasureUp website. To adjust to the current year you can use the published 2025 price year set, or adjust to the year you are wanting to use the figures for yourself.

Why Price Adjustment Matters 

The values on MeasureUp are based on extensive research into what different social outcomes are worth. However, because the cost-of-living changes over time due to inflation, using older monetary figures without updating them will give you an inaccurate picture of your project’s value in relation to today’s prices. 

Adjusting values to current prices helps your work in three main ways: 

• Accuracy is maintained because your estimates reflect what money is worth right now. 

• Consistency allows you to fairly compare different projects and ensures your costs and benefits are speaking the same financial language. 

• Credibility is preserved, giving your stakeholders confidence that your results are based on up-to-date information. 

How We Update the Numbers 

To keep things reliable, we use official inflation metrics recommended by HM Treasury. This ensures our adjustments capture broad changes in the economy and align with standard public sector practices. 

For basic economic and environmental values, we simply adjust the numbers to match standard inflation. When looking at “wellbeing” metrics, like the value of improved life satisfaction, the process goes one step further. We also factor in how national wealth changes over time, because as a society gets richer overall, the measurable impact of an extra pound on someone’s wellbeing changes slightly. 

For more information visit the Methodology page with specific information about our inflation approach including guidance sitting under the Wellbeing and Valuation section. 

A Real-World Example 

Imagine you are looking at the value of improved life satisfaction, which the government originally valued at £13,000 per person per year back in 2019. If we just used that old number today, we would be underselling the impact. By applying official government inflation and wealth data, that same outcome is correctly adjusted to £16,865 per person per year in 2025 prices. 

Tips for Your Next Project 

• Always be transparent by showing the original value, the year it was from, and your newly adjusted figure in your reports. 

• Apply your inflation updates consistently across your entire project to keep your data fair and balanced. 

• If you need to estimate future values for 2026, you can use the Time Toggle Inflation Adjustment App from Mission Economics, which uses the latest government forecasts to do the heavy lifting for you.
