Circular 2026/06 verified
Rs

Clause 2.1.1 of Circular 2026/06 allows Rs 50,000 to Rs 500,000. There is no sub-limit by Aswesuma category (clause 2.1.4).

Quick amounts

Clause 2.3.1 allows up to 60 months for this loan, and clause 2.3.3 counts any grace period inside that.

Interest-only months at the start (clause 2.2.3). The manager decides it on your request, up to 12 months (clause 2.3.2).

Clause 3 takes exactly one of these. Land and buildings are never accepted (clause 3.2.4).

Rs 37,500 on deposit

Hold Rs 37,500 in the compulsory savings account, which is one quarter of the loan applied for.

That is 25% of the loan applied for, which clause 3.1 calls the group guarantee.

Other securities open to you
  • Account-holder guarantors (clause 3.2.1): 2 guarantors
  • Large-borrower guarantors (clause 3.2.2): 2 guarantors
  • Government servant (clause 3.2.3): 1 guarantor

The account-holder route closes above Rs 200,000 (clause 3.2.1).

60 months is the longest term clause 2.3.1 allows for a loan of Rs 100,001 to Rs 500,000. A longer period needs a different loan scheme, not a longer Savibala loan.

Clause 4.3 needs prior Management Board approval above Rs 100,000, so expect to wait for the next board meeting rather than being paid on covering approval.

What the loan costs

FigureYou pay (2%)Full rate (6%)
Monthly instalmentRs 2,629.16Rs 2,899.92

Treasury subsidy, clause 2.2.1The difference between the two columnsRs 16,245.36

The full-rate column is what the same loan costs at the contracted 6%, which is what clause 2.2.4 recovers if the loan goes non-performing. The gap is the subsidy the Treasury reimburses the bank while you keep repaying on time. Interest is summed off the ledger below. Taken the short way, as instalment times months, it comes to Rs 7,749.60; the difference is the cent your bank rounds the instalment to, carried by the final month.

Month-by-month repayment schedule (60 months)

Interest on each opening balance at 2% a year, rounded to the cent, exactly as clause 2.2.2 requires. The last month settles the few cents of rounding, which is why the totals above come off this ledger rather than from instalment times months.

Full links are under Sources and references below. This is what the circular allows, not an approval: the bank still has to certify your project and your Aswesuma status.

How it works

The Savibala loan (සවිබල ණය) is the subsidised-interest livelihood loan a Samurdhi Community Based Bank issues to an identified Aswesuma beneficiary. It is set out in Samurdhi Community Based Bank Circular No. 2026/06 of 23 June 2026, which replaced the Praja Savibala loan of Circular 2025/10. It is published in Sinhala, inside a PDF in an archive of 284 circulars, so every figure below carries its clause number.

The rate, and who pays it

Clause 2.2.1 sets the annual interest at 6% and splits it: 2% payable by the borrower, 4% reimbursed to the bank by the Treasury. You are billed on the 2% only, and clause 2.2.2 computes it on the reducing balance rather than the original amount, so the interest share of your instalment falls every month. Clause 2.2.4 withdraws the concession if the loan becomes non-performing, at which point the full 6% is recovered. The calculator shows both columns, because the gap between them is what the state funds for you. For scale, compare either figure with the rates commercial banks are quoting on an ordinary personal loan.

The instalment

A reducing-balance loan repaid in level instalments is a standard annuity. With a monthly rate of i = r / 12 over n months:

A = P × i / (1 − (1 + i)−n)

At 2% the monthly rate is 0.0016667. The calculator then solves the same instalment a second way, by walking a month-by-month ledger and searching for the payment that clears the balance in exactly n months. Nothing from the formula is used in that pass, so when the two agree to the cent, as they do on every example below, the figure is verified rather than asserted. Every total is summed off that ledger.

Limits, term and grace

Clause 2.1.1 allows Rs 50,000 to Rs 500,000, with no sub-limit by Aswesuma category (clause 2.1.4). Clause 2.3.1 caps the repayment period by loan size: 48 months up to Rs 100,000, and 60 months from Rs 100,001 to Rs 500,000. A grace period of up to 12 months is the manager's to grant on request (clause 2.3.2), and during it clause 2.2.3 recovers interest only. The rule applicants miss is clause 2.3.3: grace counts inside the maximum term rather than being added to it, so six months of grace on a 60-month loan leaves 54 months to repay the principal and lifts the instalment.

Security and approval

Clause 3 takes exactly one security. The group guarantee in clause 3.1 needs 25% of the loan applied for sitting in the savings account. The alternatives are two guarantors who are active account holders of the same bank, open only up to Rs 200,000 and with one account holder allowed to guarantee one loan (clause 3.2.1); two guarantors already borrowing Rs 500,000or more and repaying properly (clause 3.2.2); or one government servant's personal guarantee (clause 3.2.3). Clause 3.2.4 is firm that immovable property is never accepted. Clause 4.3 pays a loan of Rs 100,000or less on the Management Board's covering approval, while anything above it waits for prior board approval.

Worked examples

Rs 150,000 over 60 months, no grace

A sewing machine and stock, Ratnapura

  1. Band check: Rs 150,000 sits in the Rs 100,001 to Rs 500,000 band, so 60 months is allowed (2.3.1)
  2. Monthly rate: 2% ÷ 12 = 0.0016667 (2.2.1), on the reducing balance (2.2.2)
  3. (1.0016667)^60 = 1.1050789, so 1 − (1.0016667)^−60 = 0.0950873
  4. A = 150,000 × 0.0016667 ÷ 0.0950873 = Rs 2,629.16 a month
  5. Ledger total over 60 months: Rs 157,749.87, of which Rs 7,749.87 is interest
  6. Same loan at the contracted 6%: Rs 2,899.92 a month, Rs 23,995.23 interest
  7. Treasury subsidy: 23,995.23 − 7,749.87 = Rs 16,245.36
  8. Security via savings: 0.25 × 150,000 = Rs 37,500 on deposit (3.1)
  9. Account-holder guarantors are still open, because Rs 150,000 is under Rs 200,000 (3.2.1)
  10. Approval: above Rs 100,000, so prior Management Board approval (4.3)

Rs 80,000 over 48 months with a 6-month grace

A season to wait before the first repayment

  1. Band check: Rs 80,000 is in the Rs 50,000 to Rs 100,000 band, maximum 48 months (2.3.1)
  2. Grace 6 is inside the 12-month cap (2.3.2) and counts within the term (2.3.3)
  3. So the principal amortises over 48 − 6 = 42 months, not 48
  4. Grace months: 80,000 × 0.0016667 = Rs 133.33 each, Rs 799.98 over the six
  5. (1.0016667)^42 = 1.0724457, so 1 − (1.0016667)^−42 = 0.0675519
  6. A = 133.33 ÷ 0.0675519 = Rs 1,973.79 a month for 42 months
  7. Ledger total: 799.98 + 82,899.26 = Rs 83,699.24, interest Rs 3,699.24
  8. At 6% the same loan costs Rs 11,292.88 in interest, so the subsidy is Rs 7,593.64
  9. Security via savings: 0.25 × 80,000 = Rs 20,000 (3.1)
  10. Approval: Rs 80,000 is at or below Rs 100,000, so covering approval (4.3)

Edge case: Rs 100,000 against Rs 100,001

One rupee moves the term and the approval route

  1. Rs 100,000 is the last rupee of the first band, so the term may run to 48 months only
  2. A = 166.67 ÷ 0.0768222 = Rs 2,169.51 a month over 48 months
  3. Total Rs 104,136.57, interest Rs 4,136.57, subsidy Rs 8,591.58
  4. Approval: at Rs 100,000 exactly, covering approval still applies (4.3)
  5. Add one rupee: Rs 100,001 moves into the second band, so 60 months is allowed
  6. A falls to Rs 1,752.79 a month, and interest rises to Rs 5,166.64 over the longer term
  7. Approval: Rs 100,001 needs prior Management Board approval (4.3)
  8. Rejected input: Rs 450,000 over 72 months returns no instalment, because 72 is longer than the 60-month maximum for that band (2.3.1)

Instalment at common loan sizes

The monthly instalment at the 2% borrower rate, over the longest term clause 2.3.1 allows for each amount, with no grace period. The savings column is the clause 3.1 group guarantee.

What this page does not cover

The Samurdhi bank network is large: 1,097 Community Based Banks at zonal level and 335 bank societies at regional level, with membership bought through a Rs 500 share. Those banks run 21 named loan categories besides Savibala:

Cultivation, Consumer, Swashakthi, Disaster, Livelihood Revolving, Livelihood Development, Samurdhi Sampatha, Emergency Business, Divineguma Arunalu, Ran Pradeepa (gold pawning), Employee Consumer, Sahana Piyawara, Samurdhi Abhimana, Festival Advance, New Samurdhi Entrepreneurship, Samurdhi Mutual, Samurdhi Siyapatha, Youth Entrepreneur, Samurdhi Lakjaya, Samurdhi Lak Wasana, Samurdhi Laksara.

No rate is quoted here for any of them. The most recent consolidated multi-scheme interest revision in the circular archive is Circular 2020/14 1st Addition of 11 November 2020, and publishing a 2020 rate as if it were current would be worse than publishing nothing. The same goes for the Diriya Piyasa housing programme and the Samurdhi Sipdora scholarship, which are governed by Circular 2026/09, and for the Isura and New Samurdhi Entrepreneurship loans of Rs 2 million to Rs 5 million, which bank societies issue on their own terms. If you need one of those, the archive linked below is the place to look, and I will add them here as their operative circulars are read.

The page also does not approve anything. The project manager still certifies your Aswesuma status under clause 4.1, the visiting officer still verifies that the project is viable and that you can repay (clause 2.1.2), which is easier to argue with a figure for what the household earns, such as the national minimum wage. Each bank is also working to its own Rs 12,500,000 disbursement target for 2026 (clause 2.3.4). Treat the figures here as what the circular allows, and take them to your bank as a starting point.
