Surekuma Pension Calculator — SSB Self-Employed Pension

The Sri Lanka Social Security Board was constituted under Act No. 17 of 1996 to run social security schemes for people who are not entitled to a government pension. Its self-employed scheme is Surekuma, open from age 18 to 59, paying a monthly pension from age 60. The member chooses the pension amount and the payment plan; the Board publishes the premium.

Everything is quoted per Rs 1,000. This is the fact that makes the scheme calculable. SSB does not publish a rate, a formula or an interest assumption — it publishes a premium per Rs 1,000 of monthly pension, for every single entry age from 18 to 59, for every payment option. So the arithmetic is one table lookup times a unit count:

units   = desired monthly pension / 1,000
premium = table[entry age][plan][frequency] × units
total   = premium × payments published for that plan

There is no compounding and no actuarial model in this page's code, and nothing is interpolated. Because the Board publishes a row for every age it admits, an age with no row is an ineligibility answer, never an estimate — which is why age 60returns “not eligible” rather than a number. All 879rupee figures behind the calculator were transcribed from the Board's own quotation generator on 2026-09-25.

Resolving the entry age.SSB does not use your completed age. Its rule, printed as a footnote on its quotation, is: take the difference in calendar years, and if this year's birthday has already passed, use the nextage. In effect the quoted age is the age at your next birthday. The Board's own printed example — born 1 January 2009, quoted 26 June 2026 — is priced at 18, not 17, and this tool reproduces that. Dates are compared as plain year-month-day integers, so no timezone can shift a premium by a year.

The eight plans, and when each closes. The Board publishes a pay-until-60plan (monthly or quarterly — it prints no annual figure for this one), fixed terms of 2, 3, 4, 5, 10 and 15 years (annual, monthly or quarterly), and a single payment. A fixed term is offered only where it finishes before the pension starts, so a 15-year term stops at entry age 45, a 10-year at 50, a 5-year at 55 and a 2-year at 58 — and at 59 no fixed term is available at all. That is the Board's own table extent, not a rule we invented.

How the figures check themselves. The tables are the whole tool, so a single mistyped rupee would quietly misquote somebody. Six checks run on every page load rather than being trusted once, and all six pass:

• (a) The Board's reverse table equals its pay-until-60 monthly column at every age 18–59.
• (b) A fixed term ending exactly at 60 quotes the same premium as the pay-until-60 plan — all six terms.
• (c) Pay-until-60 payment counts are (60 − age) × 12 monthly and (60 − age) × 4 quarterly at every age.
• (d) Every premium column rises strictly with entry age; no row is zero or missing.
• (e) Arassawa at 17 has one annual payment left, and its annual premium equals its single premium.
• (f) Each fixed-term table stops at entry age 60 − N, and its payment counts are N, N × 12 and N × 4.

Check (b) is the strongest of them, because it uses the Board's tables against each other. A 15-year term entered at 45 is the pay-until-60 plan, and SSB quotes both — so the two figures must match, and they do in all six cases: 2y at 58 = Rs 6,416, 3y at 57 = Rs 4,066, 4y at 56 = Rs 2,896, 5y at 55 = Rs 2,200, 10y at 50 = Rs 863, 15y at 45 = Rs 447. Check (a) does the same across the Board's forward and reverse tables, which is what lets the “premium I can afford” mode be an exact lookup rather than a division of our own.

Reverse mode.Entering what you can pay each month divides it by the Board's reverse-table figure for your age and rounds the resulting pension down to the nearest Rs 100, so the pension quoted is always one your premium actually covers. The premium for that rounded pension is then recomputed — the total and payback figures are what you would really pay, not the number you typed.

What the payback figure is not.Total premium divided by monthly pension, rounded up, is the months of pension needed to get your money back. It is not a return and not a yield. SSB publishes no interest rate for these schemes, so this page offers no projection and no opinion on whether joining beats a fixed deposit or an EPF top-up. It reports the Board's figures, the totals, and that one ratio.

The Board's pay-until-60 and single-payment columns, at ten-year steps plus both boundary ages. Multiply by your pension in thousands: a Rs 30,000 pension is 30 × the figure below. Use the calculator for your exact age and for the fixed-term plans.

Arassawa, for children aged 0 to 17, ispriced — switch to its tab in the calculator above. Death, disability and survivor benefits are not published as a table for Surekuma or Arassawa the way they are for the Farmers' Pension, so they are named and not computed.

All 879premium figures were read from the Board's own pages on 2026-09-25 and are due a re-check by 2027-03-25. The Act is cited for the legal basis of the Board and its schemes, never for a figure. All six transcription checks pass on this render. A quotation issued at an SSB district office is the binding figure.
