The Expected DA Hike Calculator on this page shows your expected Dearness Allowance (DA) from January 2027 and, as an early look, from July 2027. It uses the AICPI data released so far and the official formula.
DA is revised twice a year, from 1 January and 1 July. The revision follows the All India Consumer Price Index for Industrial Workers (AICPI-IW), which the Labour Bureau publishes every month. The official formula uses a 12-month average of these figures.
Track every open notification & never miss a deadline
Expected DA from January 2027: eight of the 12 months (January to August 2026) are out. They average 150.80 and point to 66%. That is 3 points above the 63% expected from July 2026, which is still waiting for Cabinet approval. The figure will change as September to December 2026 are released. The government rounds DA down to a whole number, and so does this calculator.

How to Use This Expected DA Hike Calculator
Using the calculator takes about a minute:
- Select the DA revision period. The calculator opens on “January 2027 DA” (AICPI January – December 2026). Click “July 2027 DA” (AICPI July 2026 – June 2027) to switch.
- Choose your pay level. This fills in the minimum basic pay for that level. You can also type your actual basic pay.
- Check the current DA rate. It is 63% for January 2027 and 66% for July 2027. Both are expected rates, not final orders, so change them if the official rate differs.
- Review the AICPI data. Released months are pre-filled. Leave pending months blank and the tool averages the months entered. Add each month as it is released.
- Click “Apply ↗”. The tool works out the expected DA% and fills it into the Expected DA field.
- Click “Calculate DA & Arrears ↗”. Your results appear with every step of the formula shown.
💡 Pro Tip: The arrears figure assumes 6 months. If the Cabinet order comes after 2 months, divide the arrears shown by 3.
Expected DA from January 2027 – Provisional Estimate
The January 2027 revision uses the average of January to December 2026. Eight of those 12 months are out so far: 148.6, 148.5, 149.1, 149.9, 150.8, 151.9, 153.2 and 154.4.
| Particulars | Details |
|---|---|
| DA Before This Revision (expected, from 1 July 2026) | 63% |
| AICPI-IW Period Used | January to December 2026 |
| Months Released | January to August 2026 (8 of 12) |
| Average of Released Months | 150.80 |
| Raw Formula Result | 66.15% |
| Provisional DA from 1 January 2027 | 66% |
| Official Status | [Not yet announced] |
This number will move. If September to December 2026 stay at the August level of 154.4, the full-year average becomes 152.0 and the raw result is about 67.47%, which is a DA of 67%. That is an illustration, not a forecast.
The new rate applies from 1 January 2027. The Cabinet order usually comes a few months later, often around March, with the difference paid as arrears.
⚠️ The 63% base is itself an estimate until the July 2026 order is issued. If the official July 2026 rate is different, update the “Current DA Rate” box in the calculator.
Expected DA Hike July 2027 – Very Early Estimate
The July 2027 revision uses the average of July 2026 to June 2027. Only two of the 12 months are out so far: 153.2 for July 2026 and 154.4 for August 2026.
| Particulars | Details |
|---|---|
| AICPI-IW Period Used | July 2026 to June 2027 |
| Months Released | July and August 2026 (2 of 12) |
| Average of Released Months | 153.80 |
| Raw Formula Result | 69.45% |
| Provisional DA from 1 July 2027 | 69% |
| Official Status | [Not yet announced] |
⚠️ Two months are too few to rely on. The figure will change a lot as the next ten months come in, and it depends on the January 2027 rate being confirmed first. Treat it as a first look only.
What Is the Official DA Calculation Formula? (7th CPC)
The Government of India uses this formula for 7th Pay Commission employees:
DA% = [(Average AICPI-IW × 2.88) − 261.4] ÷ 261.4 × 100
The result is rounded down to a whole number. Here is what each part means:
- Average AICPI-IW: the 12-month average of the index (base year 2016 = 100) published by the Labour Bureau.
- 2.88: the linking factor that converts the 2016 series back to the older 2001 series used in the 7th CPC structure.
- 261.4: the average AICPI for 2015-16 on the 2001 series. Some sources write it as 261.42, which changes the raw result by about 0.01 point and does not change the final DA.
- Rounded down: 63.97% becomes 63%, not 64%.
Worked Example – January 2027 DA (8 Months So Far)
Using January to August 2026, the sum is 1,206.4 and the average is 150.80.
| Step | Calculation | Result |
|---|---|---|
| ① Average AICPI | 1,206.4 ÷ 8 | 150.80 |
| ② × Linking factor 2.88 | 150.80 × 2.88 | 434.30 |
| ③ − Base constant 261.4 | 434.30 − 261.4 | 172.90 |
| ④ ÷ 261.4 × 100 | (172.90 ÷ 261.4) × 100 | 66.15% |
| ⑤ Round down | Floor(66.15%) | 66% |
⚠️ This uses only 8 months. Add September to December 2026 in the calculator as they are released.
AICPI-IW Data Used in the Calculator
The Labour Bureau releases the index on the last working day of the following month. The table shows which months feed each revision.

💡 This table and the calculator are updated each time the Labour Bureau releases a new month.
DA Arrears – How Much Will You Get?
A new DA rate applies from 1 January or 1 July, but the order usually comes a few months later. The Cabinet then pays the difference for the months already passed as arrears.
Arrears = (New DA amount − Old DA amount) × number of months from the effective date until the new rate is paid
For an employee at Level 6 (basic pay ₹35,400) with DA rising from 63% to 66% in January 2027:
| Particulars | Amount |
|---|---|
| DA at 63% | ₹22,302 per month |
| DA at 66% | ₹23,364 per month |
| Increase | ₹1,062 per month |
| Arrears if paid for 2 months (January–February 2027) | ₹2,124 |
| Arrears if paid for 6 months (January–June 2027) | ₹6,372 |
The calculator shows the 6-month figure by default. Adjust it to match the month your order actually arrives.
Pensioners – Dearness Relief (DR) Hike
Pensioners receive Dearness Relief (DR) instead of DA, at the same rate. If DA rises from 63% to 66%, DR rises by the same 3 points from the same date.
For a pension of ₹30,000 per month:
- DR at 63%: ₹18,900 per month
- DR at 66%: ₹19,800 per month
- Increase: ₹900 per month
- Arrears for 2 months: ₹1,800
Will HRA Change After the DA Hike?
House Rent Allowance (HRA) under the 7th CPC changes only when DA crosses fixed thresholds.
| When DA Crosses | HRA Rates (X / Y / Z cities) |
|---|---|
| 25% | 27% / 18% / 9% |
| 50% | 30% / 20% / 10% |
DA crossed 50% back in the January 2024 revision, so the 30%, 20% and 10% rates already apply. A rise to 66% or 69% does not trigger a fresh HRA revision.

Frequently Asked Questions
What is the expected DA from January 2027?
Using January to August 2026 data, the expected DA from January 2027 is 66%, about 3 points above the expected 63% from July 2026. The figure will change as September to December 2026 AICPI numbers are released. The calculator updates the estimate each time you add a new month.
What is the expected DA hike from July 2027?
Only July and August 2026 are out for the July 2027 cycle, and they point to about 69%. That is a very early figure and will change a lot as the next ten months are released. Use the calculator to track it as new data comes in.
How do I calculate the expected DA hike?
Use the formula DA% = [(12-month average AICPI-IW × 2.88) − 261.4] ÷ 261.4 × 100, then round down to a whole number. The calculator on this page does all the steps once you enter the monthly AICPI figures. It also shows each step so you can check the working.
What is the current DA rate for central government employees?
The current DA rate is 60% of basic pay, effective from 1 January 2026. It was raised from 58% after the Union Cabinet approved a 2-point hike in April 2026. The July 2026 revision is decided separately.
When will the January 2027 DA be announced?
The new rate applies from 1 January 2027, but the Cabinet order usually comes a few months later, often around March. The full January to December 2026 data is needed first. Employees then receive arrears for the months already passed.
When will the July 2026 DA hike be announced?
The new rate applies from 1 July 2026, but the Cabinet usually clears the July DA between September and October. Employees then receive the difference for the earlier months as arrears. Check the latest news on this site for the official order.
How are DA arrears calculated?
Arrears equal the monthly DA increase multiplied by the number of months from 1 July 2026 until the new rate is paid. For a Level 6 employee with a basic pay of ₹35,400, the increase is ₹1,062 per month. That makes ₹3,186 for 3 months or ₹6,372 for 6 months.
Does this calculator work for July 2027 DA?
Yes. Click the July 2027 DA button at the top of the calculator. It loads the July 2026 to June 2027 AICPI period, pre-fills the two months released so far and sets the current DA to 66%. Add the remaining months as the Labour Bureau publishes them.
Do pensioners get the same hike?
Yes. Pensioners receive Dearness Relief at the same rate as DA for serving employees. If DA goes to 63%, DR also goes to 63% from the same date, and the arrears are paid in the same way.
Why is DA rounded down?
The government drops the decimals when it fixes the DA percentage. A raw result of 63.80% therefore becomes 63%, not 64%. The calculator follows the same rule.
Will the January 2027 DA hike change my HRA?
No. HRA changes only when DA crosses 25% or 50%. DA passed 50% in January 2024, so a move to 66% or 69% does not trigger a new HRA revision.
Final Word on the Expected DA Hike Calculator
January 2027 is on track for a DA near 66% on the eight months released so far, and July 2026 points to 63%. Use the Expected DA Hike Calculator above to see your own figures, and come back as each new AICPI month is published.
