Both are the honorable jobs for you to perform. However the IAS is much powerful than IPS because after completing 8 years in Indian administrative Service you can become the district magistrate of your  city in which you are posted and which makes you the top authority of the city. However I am mentioning below the points of comparison between Indian administrative Service and Indian police service for making a clear understanding for you:

Indian administrative Service:

• UPSC conducts Indian administrative Services examinations it is conducted once in every year. The maximum age 32 years upto which you can give examination for UPSC.
• After becoming an IAS you can expect a salary of 56100 per month if you become sub divisional magistrate. And after completing 8 years you will become district magistrate and you can expect a salary of 78800 per month.
• You will also get facilities of government accommodation, security, household assistant including cook etc when you become an IAS officer.

Indian police service:

• UPSC conducts Indian police Service examination and you have to qualify the examination for being an Indian police Service authority.
• Every year aspirants between 5 to 8 lakh appear for union Public Service Commission examination for becoming an IPS officer.
• You have to qualify three examinations for becoming a IPS officer. These examinations are civil services preliminary, civil services mains and UPSC personality test.
• According to the 7th pay commission the director General of police get a salary of 225000 and additional director General of police get a salary of 2,05,000.

It can be said that both of the positions are good but district magistrate IAS avails  more facilities than IPS.

Hello Aspirant,

Hope you are doing well. As per your query let me tell you that Both IAS and IPS are very powerful positions in their respective fields but IAS is much more powerful than the IPS. An IPS has only the responsibility of its department, but an IAS has the responsibility of all the departments of the district. An IAS officer is the head of the police department too. The IAS officers get the fastest promotion in India. A typical IAS officer gets 2-4 years of advantage in terms of promotion as compared to IPS.

Hope it will help you

Thank you.
