Step-by-step formula under CCS (Leave) Rules, complete worked example with real 7th CPC pay numbers, EL encashment at retirement vs. during service, and tax exemption rules.
Leave encashment is one of those retirement benefits that Central Government employees consistently underestimate — until they are within a year of superannuation and realise it can amount to ₹8–10 lakh in a single tax-free payment. Yet the calculation confuses many people, largely because there are two separate scenarios (retirement vs. during service), two types of leave that behave differently (Earned Leave and Half Pay Leave), and a formula that looks simple but has a few non-obvious inputs.
This guide explains the complete leave encashment calculation from first principles — the formula, the inputs, a fully worked example using actual 7th CPC pay numbers, and the rules that govern how much you can actually encash and when.
Under the CCS (Leave) Rules, 1972, Central Government employees are entitled to several types of leave. However, not all leave types are eligible for encashment. Here is what matters:
| Leave Type | Encashable at Retirement? | Encashable During Service? | Max Days Encashable |
|---|---|---|---|
| Earned Leave (EL) | ✅ Yes | ✅ Yes (LTC-linked only) | 300 days (lifetime cap) |
| Half Pay Leave (HPL) | ❌ No | ❌ No | Not encashable |
| Commuted Leave | ❌ No | ❌ No | Not encashable |
| Extra-ordinary Leave | ❌ No | ❌ No | Not encashable |
| Casual Leave (CL) | ❌ No | ❌ No | Lapses unused |
The key takeaway: only Earned Leave (also called Privilege Leave in some departments) is encashable. Your accumulated HPL balance, however large, has no cash value at retirement. This is a common misconception — many employees assume their entire leave balance is encashable. It is not.
The formula prescribed under Rule 39 of CCS (Leave) Rules, 1972 and subsequent DoPT instructions is:
A few important clarifications about each variable in this formula:
Let's work through a complete, realistic example. Consider a Level 10 employee (Assistant Engineer / Section Officer grade) retiring on superannuation on 31 May 2026, with the following parameters:
| Parameter | Value |
|---|---|
| Pay Level | Level 10 (Pay Matrix) |
| Basic Pay on date of retirement | ₹56,100 |
| DA (as of May 2026) | 55% = ₹30,855 |
| Total Pay Emoluments (Basic + DA) | ₹86,955 |
| Per Day Emolument (÷ 30) | ₹2,898.50 |
| EL balance on date of retirement | 284 days |
| Leave Encashment Amount | ₹8,23,534 |
Step-by-step calculation:
This ₹8.23 lakh is received as a lump sum along with the final settlement — and for a Central Government employee, the entire amount is exempt from income tax. Compare this with the gratuity payment (calculated separately — see our Gratuity Calculator); together, these two terminal benefits can amount to ₹20–25 lakh for a Level 10 employee with 30+ years of service.
Skip the manual math — enter your pay level, DA, and EL balance to get your exact leave encashment amount instantly.
Calculate My Leave Encashment →Leave encashment is not only available at retirement. Central Government employees can also encash Earned Leave during their service, but only in conjunction with Leave Travel Concession (LTC). The rules here are more restrictive:
The 60-day lifetime cap on in-service encashment is independent of the 300-day retirement encashment limit. Using LTC encashment during service does not reduce the 300-day cap available at retirement.
Earned Leave accrues at the rate of 2.5 days per calendar month (30 days per year) for Central Government employees. The maximum EL that can stand to your credit at any point is 300 days — there is a hard cap. This means that if you already have 300 days accumulated, further accrual simply lapses unless you take leave to bring the balance below 300.
| Scenario | EL Accrual Rate | Max Balance | Notes |
|---|---|---|---|
| Regular service | 2.5 days/month (30/year) | 300 days | Standard CCS (Leave) Rules |
| Year with sick leave taken | 2.5 days/month, unaffected | 300 days | Sick/HPL does not affect EL accrual |
| Employee on EOL | No accrual during EOL period | 300 days | EL does not accrue during Extra-ordinary Leave |
| Year with maternity/paternity leave | 2.5 days/month, unaffected | 300 days | Special leaves do not affect EL accrual |
| At superannuation | — | Max 300 days encashable | Full balance up to cap is paid out |
Practically, an employee who takes minimal leave over a long career will reach the 300-day cap well before retirement. Once at 300 days, every month of further service that goes without leave-taking results in 2.5 days lapsing. This is why DoPT and most ministry circulars encourage employees to actually utilise leave rather than accumulate it indefinitely — the benefit is capped regardless.
For Central Government employees, leave encashment received at the time of retirement (superannuation, voluntary retirement, or compulsory retirement) is completely exempt from income tax under Section 10(10AA)(i) of the Income Tax Act, 1961. There is no monetary ceiling on this exemption for government employees — the full amount, even if it is ₹10+ lakh, is tax-free. You do not need to declare it as income, and no TDS is deducted.
This is meaningfully different from the treatment for private sector employees, for whom Section 10(10AA)(ii) caps the exemption at ₹25 lakh (revised from ₹3 lakh effective April 2023). Government employees have no such cap — a useful benefit worth keeping in mind when comparing retirement packages. Use our Income Tax Calculator to see how your total taxable income looks in the year of retirement after this exemption.
In-service leave encashment (LTC-linked) is fully taxable as salary income. There is no exemption under Section 10(10AA) for encashment during service — that provision applies only to terminal encashment. The amount gets added to your gross salary for the year and taxed at the applicable slab rate. Factor this into your planning if you are considering LTC encashment in a high-income year.
If an employee passes away while in service, the leave encashment payable to the family (for EL balance at time of death, up to 300 days) is also fully tax-free under Section 10(10AA). The family gets the same formula-based amount without any tax deduction.
Employees who take Voluntary Retirement under CCS (Pension) Rules are also entitled to full EL encashment (up to 300 days) on the date of VRS, at the same formula. The calculation is identical to superannuation encashment. The Basic Pay and DA used are those applicable on the VRS date, and the full amount is tax-free under Section 10(10AA).
For BSNL employees specifically, the VRS 2.0 package announced in 2026 includes a leave encashment component. Use our BSNL VRS 2026 Calculator to see the complete VRS benefit calculation including leave encashment, gratuity, and ex-gratia in a single view.
A few points worth keeping in mind in the years before retirement:
The formula is: (Basic Pay + DA) ÷ 30 × Number of EL days encashed. Only Basic Pay and Dearness Allowance are included — HRA, TA, and other allowances are excluded. The divisor is always 30 regardless of the month. At retirement, up to 300 days of Earned Leave can be encashed using this formula.
The CCS (Leave) Rules formula is: Leave Encashment = (Basic Pay + DA) ÷ 30 × EL days. For example, with Basic Pay ₹56,100, DA 55% (₹30,855), and 284 days of EL: (₹56,100 + ₹30,855) ÷ 30 × 284 = ₹2,898.50 × 284 ≈ ₹8,23,174. The per-day rate (Basic + DA ÷ 30) is the key figure — multiply it by your EL balance to get your encashment amount.
At superannuation or VRS, you can encash up to 300 days of Earned Leave using the formula (Basic Pay + DA) ÷ 30 × EL days. The DA applied is that prevailing on the date of retirement — so a DA revision just before retirement increases your payout. The entire amount is fully exempt from income tax under Section 10(10AA)(i). Half Pay Leave is not encashable at retirement.
Leave encashment received at retirement is fully tax-free under Section 10(10AA)(i) of the Income Tax Act — no upper limit applies to Central Government employees. Leave encashment during service (LTC-linked, up to 10 days per journey) is fully taxable as salary. In case of death in service, the encashment paid to family is also tax-free. The tax-free treatment at retirement is a significant advantage over private sector employees, who have a ₹25 lakh cap on the exemption.
