Sri Lanka Festival Advance Calculator

Sri Lankan public officers can draw an interest-free festival advance before every major festival and for the Sri Pada and Hajj pilgrimages. This calculator gives you the monthly salary deduction, the total repayable, the exact settlement month, and a full month-by-month recovery table. Switch tabs to model the separate special annual advance, which carries 8% interest a year on the reducing balance. Enter your net salary to see take-home pay after each deduction.

The festival advance is governed by the Establishments Code, Chapter XXIV, Section 13. It is interest-free and recovered from salary in equal monthly installments starting the month after it is drawn. The calculator uses the recovery method set out in the Code and the Public Administration Circulars:

1. Base installment. The advance is split into whole-rupee equal deductions: base = floor(amount ÷ installments). The first months each deduct the base amount.
2. Final installment. The last month absorbs any rounding remainder — final = amount − base × (installments − 1) — so the schedule sums to the advance exactly.
3. Interest. Zero for the festival advance, so total repayable equals the amount drawn. For the special annual advance, interest is charged monthly on the outstanding balance at interest = opening balance × (8% ÷ 12), a reducing-balance method, and each installment is principal + that month's interest.
4. Settlement. Recovery starts the month after drawing, so the balance clears in drawn month + installments. Default counts are 8 months (festival) and 10 months (special annual, always cleared by 31 December).

The special-advance interest is cross-checked by an independent reducing-balance re-computation, so the total interest shown is the sum of interest on each month's opening balance to the rupee. The tool is a planning aid — your department's pay office applies the official figures.
