For the covered bill-collection population, RBI’s interest measure is two percentage points per annum above the savings-bank balance rate, after allowing the normal transit periods specified in paragraph 155. It is not a flat daily compensation amount or automatically the repo rate plus a margin.
Applicable current directions
This guide applies RBI Commercial Banks — Responsible Business Conduct Directions, 2025, updated 1 October 2026, paragraphs 154–156, checked on 25 October 2026. The official current listing confirms that version. The population is commercial banks as defined in those Directions, not every lender or payment provider. Identify an actual bill for collection rather than assuming all cheque, NEFT, export or credit-card transactions use this calculation.
Direct forwarding and stage evidence
Paragraph 154 addresses bills for collection, including discounted bills, required to be collected through another bank at the realising centre, and requires direct forwarding by the forwarding office to the realising office. Retain lodgement, dispatch, presentation, realisation, remittance and credit records. A customer’s invoice due date is not automatically the starting date for every bank-controlled collection step. The contractual/usance period and actual collection events need separate analysis.
Use the four transit allowances correctly
Paragraph 155 allows two days each for dispatch of bills, presentation to the drawer’s bank, remittance to the lodger’s bank and credit to the lodger. The four listed allowances total eight days. That arithmetic is a control for the identified collection process, not permission to subtract eight from any arbitrary period beginning when the commercial invoice was issued. Determine the actual relevant process and eligible delayed period from the records before multiplying interest.
Rate, basis and interbank recovery
The paragraph links interest to the rate payable on savings-bank balances plus two percentage points per annum. Obtain the applicable rate and the supported amount on which interest is due; do not use a deposit advertisement from an unrelated period. Paragraph 156 allows the lodger’s bank to recover interest from the drawer’s bank to the extent delay is attributable there. Keep that bank-to-bank recovery separate from the interest payable to the lodger. The text should not be rewritten to make the customer’s entitlement depend on successful interbank reimbursement.
Calculation assumptions and closing checks
The examples assume the relevant process, principal base and delayed period are independently established, with no usance, part-period rate change, export-specific or other special complication unless described. All savings rates below are hypothetical, not current RBI or bank rate quotations. Interest uses simple actual-days/365 and paise rounding as a model, not a claimed RBI-prescribed day-count convention. Check the actual bank’s supported computation and avoid counting an already-compensated period twice. Preserve the principal, rate, dates, delay attribution and payment record together.
Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Four listed transit stages
Two days each for dispatch, presentation, remittance and credit total 2 + 2 + 2 + 2 = 8 days. If the independently established collection-process period is 14 days and all four allowances apply, the simple model delay is six days.
Illustrative example 2: Savings rate plus percentage points
Assume principal ₹3,65,000, hypothetical savings rate 3% and six eligible delay days. Annual rate 3% + 2 percentage points = 5%. Interest ₹3,65,000 × 5% × 6/365 = ₹300.00.
Illustrative example 3: A different established savings rate
Principal ₹7,30,000, hypothetical savings rate 2.5% and ten eligible delay days give annual 4.5%. Interest ₹7,30,000 × 4.5% × 10/365 = ₹900.00. The extra two points are not 2% of the 2.5% savings rate.
Illustrative example 4: Do not create negative delay
An established seven-day process with all eight allowance days applicable produces no positive delay in this simplified model: max(0, 7 − 8) = 0. Interest is ₹0; no negative compensation is recorded.
Illustrative example 5: Separate customer interest and bank recourse
Assume six eligible delay days on ₹3,65,000 at the illustrative 5% rate: customer interest ₹300. Of those days, four are established as attributable to the drawer’s bank. Model interbank recovery ₹200, leaving ₹100 associated with the other two days. The customer calculation remains ₹300.
Illustrative example 6: Use independently established tranches
Assume two separately supported bill bases each have applicable rate 5%: ₹3,65,000 delayed two days and ₹1,82,500 delayed four days. Interest is ₹100 + ₹100 = ₹200. Do not apply the longest delay to both without evidence.
Ten-step verification table
| Step | Action | Evidence |
|---|---|---|
| 1 | Identify transaction population | Bill collection rather than a different payment mechanism. |
| 2 | Verify bank scope | Current covered commercial-bank framework. |
| 3 | Retain lodgement and routing | Direct forwarding and realising-office evidence. |
| 4 | Build the stage chronology | Dispatch, presentation, realisation, remittance and credit records. |
| 5 | Separate commercial maturity | Usance and invoice periods outside the modelled bank delay. |
| 6 | Apply the transit allowances | Supported two-day stages and relevant process period. |
| 7 | Establish principal and rates | Amount due and applicable savings-rate evidence. |
| 8 | Calculate interest independently | Eligible delay, annual margin and supported day count. |
| 9 | Analyse interbank responsibility | Drawer-bank attribution and separate recourse working. |
| 10 | Reconcile customer payment | Interest credited, prior compensation and unresolved differences. |
Sixteen practitioner FAQs
1. Which current paragraphs govern this guide?
Paragraphs 154–156 of the cited bank Directions.
2. Does every payment delay use this formula?
No. Identify the applicable bill-collection population.
3. Are discounted bills mentioned?
Yes, in paragraph 154’s stated routing population.
4. How should the bill be routed there?
Directly from forwarding office to realising office on the provision’s terms.
5. What is the annual margin?
Two percentage points above the applicable savings-bank balance rate.
6. Is the measure repo plus two?
Not under this cited paragraph.
7. How many transit stages are listed?
Four, with two days each.
8. Does that always mean eight days from invoice issue?
No. Establish the relevant collection chronology and commercial maturity separately.
9. Can the delay become negative?
The simple interest model does not generate a negative compensation period.
10. Are the example rates actual market rates?
No. They are explicitly hypothetical.
11. Is actual/365 claimed as the prescribed RBI convention?
No. It is the disclosed illustration convention.
12. Should separate bill amounts share the longest delay automatically?
No. Use the independently established tranche dates.
13. Who pays interest to the lodger under paragraph 155?
The lodger’s bank.
14. What does paragraph 156 permit?
Recovery from the drawer’s bank to the extent of attributable delay.
15. Does interbank recourse replace the customer working?
No. Maintain the two reconciliations separately.
16. What evidence is most useful in a complaint?
Stage dates, amount, rate, eligible delay and actual interest-credit records.
Conclusion
RBI paragraph 155 links delayed bill-collection interest to the savings rate plus two percentage points after the stated transit allowances. Preserve stage dates and distinguish the lodger’s payment from interbank recovery.
