EPS pension is generally calculated using the member's pensionable salary and pensionable service. Under the standard formula, pensionable salary is multiplied by eligible pensionable service and divided by 70. The actual pension payable depends on the applicable EPS provisions and the member's eligibility.

For eligible members who qualify for a higher pension based on actual salary, the pension is generally calculated using the applicable pensionable salary based on the member's eligible higher-salary contribution and pensionable service, divided by 70. The exact calculation is subject to EPFO rules, eligibility, contribution requirements, and applicable orders.

Pensionable salary is the salary considered for determining an employee's EPS pension. Under the standard EPS framework, it is generally based on the prescribed salary ceiling and the applicable average salary period under the scheme. Members eligible for higher pension may be subject to different provisions.

Generally, an eligible member needs at least 10 years of eligible pensionable service to qualify for a monthly EPS pension. The applicable EPS rules determine how pensionable service is calculated and whether a member meets the eligibility requirements.
