One contribution, two destinations
The employee's 12% contribution goes entirely to EPF. The employer's matching 12% is where the split happens — up to 8.33% of basic (capped at ₹1,250/month) is diverted to EPS, and the rest joins the EPF corpus alongside the employee's contribution.
EPF: a lump-sum corpus
For a ₹30,000 basic salary, working age 25 to 58 with a 5% annual raise, the EPF contribution calculator projects a corpus at retirement of ₹2,29,27,834.84 — this is money that accumulates with interest and is withdrawn as a lump sum (or partially, for eligible reasons, before retirement).
EPS: a monthly pension for life
EPS works completely differently — it isn't a savings balance at all, but an entitlement to a fixed monthly payment calculated from capped average salary and years of service. For an average salary of ₹20,000 (capped at ₹15,000) and 20 years of pensionable service, the EPS pension calculator gives ₹4,285.71 per month, paid out for life after eligibility age rather than withdrawn as a single sum.
Why both figures matter for retirement planning
The EPF corpus and the EPS pension answer different retirement questions: EPF is "how much money will I have saved up," while EPS is "how much guaranteed monthly income will I receive." Because part of the employer's contribution is permanently diverted from EPF to fund EPS, a full retirement picture needs both calculators — looking at EPF projections alone understates the employer's actual total contribution, since the EPS portion doesn't disappear, it just becomes a different kind of benefit.
