pension calculation is not complicated. it follows a formula. the challenge is knowing which formula applies to the specific scheme.
here is how pension is calculated under different schemes. and how to estimate the retirement corpus.
eps pension formula. the standard calculation
the employees’ pension scheme uses a fixed formula. monthly pension = (pensionable salary × pensionable service) / 70 .
pensionable salary is the average monthly salary drawn in the last 60 months before retirement. the maximum considered is ₹15,000 per month .
pensionable service is the total years of eligible service .
a member with 30 years of service and a pensionable salary of ₹15,000 gets a monthly pension of approximately ₹6,429 . for 35 years of service, the maximum pension is ₹7,500 per month .
the formula remains unchanged under eps-2026, which replaced eps-1995 from april 1, 2026 . the minimum pension guarantee of ₹1,000 per month continues .
pensionable salary for different situations
for most employees, the pensionable salary is capped at ₹15,000. even if the actual salary is higher, the calculation uses the cap . a 2023 supreme court judgment allowed employees to contribute 8.33% of their actual salary above the cap for a higher pension.
commutation. converting pension to a lump sum
commutation means receiving a portion of the pension as a lump sum. the remaining monthly pension reduces accordingly .
the formula for commuted value is: commuted value = portion of pension to commute × 12 × commutation factor .
a basic pension of ₹60,000 with 40% commutation at age 61 gives a lump sum of approximately ₹23.6 lakh. the monthly pension then reduces to ₹36,000 for 15 years, after which the full pension is restored .
government employees can commute up to 40% of their pension. commuted pension is fully tax-exempt for government employees .
retirement corpus for non-government pensions
for non-government employees, pension depends on the accumulated corpus. the corpus formula is: fv = pv × (1 + r)^n . a 42-year-old with current monthly expenses of ₹50,000 planning to retire at 60 needs a corpus of roughly ₹2.67 crore .
nps pension calculation
nps provides a calculator to estimate pension wealth. the output includes corpus accumulated at retirement, lump sum withdrawal, and monthly annuity .
