Official vs estimate
Two kinds of numbers appear on this site. Official numbers come from a Government order or release we have read: the current DR rate (60%), the minimum and maximum pension, family pension rates, additional pension for age, Fixed Medical Allowance and the 7th CPC pre-2016 methods. Estimates are anything about the 8th Pay Commission — the fitment factor, the new minimum and maximum, DR after revision, the date of effect and arrears — and any DR rate not yet announced. Every estimate is labelled "Estimate — not official" on screen.
Rounding
Pension, additional pension and DR are rounded up to the next rupee. DR orders say so explicitly ("The payment of Dearness Relief involving a fraction of a rupee shall be rounded off to the next higher rupee"), and the 7th CPC orders rounded revised pension "off to next higher rupee". The code first trims floating-point noise (so 23,129.999… becomes 23,130), then rounds up.
Current pension (7th CPC)
Additional pension = basic × age % · DR = (basic + additional) × DR % · Total = basic + additional + DR
- Age %: 20% from 80, 30% from 85, 40% from 90, 50% from 95, 100% from 100 years (OM 04.08.2016 para 4.5; CCS (Pension) Rules, 2021).
- DR: 60% from 01.01.2026, paid on basic plus additional pension (DoPPW OM 24.04.2026).
- Limits: minimum ₹9,000; maximum ₹1,25,000 for pension and enhanced family pension, ₹75,000 for normal family pension (50% / 30% of the highest pay of ₹2,50,000).
8th CPC estimate (main calculator)
New basic = basic × fitment factor (rounded up), raised to new minimum = ₹9,000 × factor, limited to new maximum = 7th CPC maximum × factor
New total = new basic + new basic × age % + DR after revision (assumed 0%)
Arrears = max(0, new total − current total) × months from date of effect to the month before first payment
Assumptions, all changeable on screen: the factor you pick (none is official); the 7th CPC method of a single multiplier; DR restarting at 0%; date of effect 1 January 2026 (the Government said effect "would normally be expected" then, based on past practice); today's DR used for the whole arrears period. Commutation, income tax and FMA are excluded.
Pre-2016 pensioners
Method A = pension on 31.12.2015 × 2.57 (rounded up, min ₹9,000)
Method B = notional pay on 01.01.2016 × 50% (pension, enhanced family pension) or 30% (normal family pension), rounded up
7th CPC basic = higher of A and B, within the limits above
Method B's notional pay is entered by the user from their revised PPO; we do not compute notional fixation because it needs each pensioner's scale history and the DoPPW concordance tables. The calculator reproduces all four pension examples in Annexure I of the 12.05.2017 OM (₹11,550, ₹35,900, ₹14,800 and ₹1,02,550). The 8th CPC estimate then applies the chosen factor to the 7th CPC basic.
Basic pension finder
Credit = basic + additional + DR − commutation deduction + FMA (₹1,000 if ticked) − other deductions
The tool inverts this formula by testing every whole-rupee basic pension near the algebraic estimate and keeping the one that reproduces the credit exactly (or the nearest, with the difference shown). DR is applied to the full pension before commutation, as DoPPW's Pensioners' Portal states. When the commutation is entered as a percentage, the deduction is approximated as basic × % rounded to the nearest rupee; the rupee amount from the PPO is more accurate. PPO modes: a post-2016 PPO basic is used as is; a 31.12.2015 pension is × 2.57 (min ₹9,000); last pay gives 50% (pension), 30% or 50% (family pension) within the limits.
DA / DR calculator
DR = (basic + additional) × rate, rounded up · Monthly increase = DR(new) − DR(old) · Arrears = increase × months from date of effect to the month before first payment
Basic pension and age slab are held constant over the arrears period, and arrears are shown before any income-tax deduction. The pre-filled new rate (63%) is an estimate until an order is issued; it is labelled as such.
Where the numbers live
All rates are kept in one settings block in the site's script, and published in machine-readable form at /assets/rates.json (generated from the same settings, so the two cannot disagree). When an order changes a rate, we update it, record the change with its date and source on the changelog, and change the "data last updated" date shown on every page.

Commutation and restoration
Monthly deduction = basic pension × % commuted (or the rupee amount on the PPO) · Lump sum ≈ deduction × commutation factor × 12 · Restoration = 15 years after the deduction started
The commutation factor is taken from the commutation table for the age next birthday (8.194 at 61, the usual case for retirement at 60). DR is paid on the full pension. For the 8th CPC estimate we assume, as in the 7th CPC revision (OM 04.08.2016 para 4.3), that the deduction stays at the same rupee amount until restoration.
