Frequently Asked

Common Questions

01Are the calculators accurate for CCS Rules?
Each calculator is built to match the formula and rates in the relevant CCS Rule or Finance Bill, with the rule referenced on the same page. They give a reliable estimate — always confirm the final figure with your DDO or PAO before relying on it for an official claim.
02Are the service guides from official government records?
Guides are written in plain language but reference official sources — CCS Rules, DoPT OMs and circulars — which are linked on each article. CSSMitra is independent and not affiliated with DoPT or the Government of India.
03Do I need an account to use the calculators?
No. All calculators are completely free and require no login. Just open any calculator and start using it.
04Is my salary data safe? Is anything uploaded to your server?
All calculators run entirely in your browser. Your basic pay, DA, tax and pension figures never leave your device. We have no servers receiving this data.
05Which service rules do the guides cover?
CCS (Pension) Rules 2021, CCS (Leave) Rules 1972, CCS (CCA) Rules 1965, FR/SR, DFPR 2024, Vigilance Manual and related DoPT instructions — written for Central Government employees and pensioners.
06How often is content updated?
Guides and calculators are updated whenever DA rates, tax slabs or a service rule changes. If you spot something outdated, use the feedback form and we'll correct it.
