In its 2010 Human Development Report, the UNDP began using a new method of calculating the HDI. The following three indices are used:

1.{{anchor|Life Expectancy Index}} Life Expectancy Index (LEI) <math>= \frac{\textrm{LE} - 20}{85-2065}</math>

::LEI is equal to 1 when [[life expectancy at birth]] is 85 years, and 0 when life expectancy at birth is 20 years.

2. [[Education Index]] (EI) <math>= \frac{{\textrm{MYSI} + \textrm{EYSI}}} {2}</math><ref>{{Cite news|url=http://www.indiastudychannel.com/resources/141517-New-method-of-calculation-of-Human-Development-Index-HDI.aspx|title=New method of calculation of Human Development Index (HDI)|date=1 June 2011|work=India Study Channel|access-date=19 November 2017|language=en|archive-url=https://web.archive.org/web/20171110171412/http://www.indiastudychannel.com/resources/141517-New-method-of-calculation-of-Human-Development-Index-HDI.aspx|archive-date=10 November 2017|url-status=live}}</ref>

:2.2 Expected Years of Schooling Index (EYSI) <math>= \frac{\textrm{EYS}}{18}</math><ref>(ESYI is a calculation of the number of years a child is expected to attend school, or university, including the years spent on repetition. It is the sum of the age-specific enrollment ratios for primary, secondary, post-secondary non-tertiary and tertiary education and is calculated assuming the prevailing patterns of age-specific enrollment rates were to stay the same throughout the child's life. Expected years of schooling is capped at 18 years. (Source: UNESCO Institute for Statistics (2010). Correspondence on education indicators. March. Montreal.)</ref>

:: Eighteen is equivalent to achieving a [[master's degree]] in most countries.

3. Income Index (II) <math>= \frac{\ln(\textrm{GNIpc}) - \ln(100)}{\ln(75,000) - \ln(100750)}</math>

::II is 1 when GNI per capita is $75,000 and 0 when GNI per capita is $100.

Finally, the HDI is the [[geometric mean]] of the previous three normalized indices:
