How the Ogden Tables Work in Loss of Earnings Claims
This guide explains how UK loss of earnings experts use the Ogden Tables — multipliers, multiplicands, discount rates, employment contingencies, and when courts use Smith v Manchester or Blamire awards instead.
History and Purpose of the Ogden Tables
The Ogden Tables are actuarial tables published by the Government Actuary's Department (GAD). They exist to convert a stream of future financial losses — principally future loss of earnings — into a present lump-sum value that courts and parties can use in personal injury and clinical negligence claims in England and Wales. Named after Sir Michael Ogden QC, the tables provide a consistent, publicly available method for calculating multipliers.
How to Read the Tables — Which Table, Which Multiplier
Table selection depends on the claimant's age at the date of assessment, sex, assumed retirement age, and whether the calculation is for earnings to retirement or other periods of loss. The expert identifies the correct row and column, then applies any employment contingency reduction factors required by the evidence. The chosen table, multiplier, and reasoning must be disclosed in a CPR Part 35 report.
The Discount Rate — What It Is and How It Applies
The personal injury discount rate, set by the Lord Chancellor, adjusts multipliers for the time value of money and assumed investment returns on a lump-sum award. A change in the discount rate can materially increase or decrease future loss quantum. Experts must apply the rate in force at the relevant date and state it clearly in the report.
Employment Contingency Reductions — Tables A–D
Employment contingency reduction factors (commonly discussed by reference to Tables A–D in the Ogden methodology) adjust the multiplier for risks such as unemployment, disability, and other contingencies that would have affected earning capacity even without the injury. Application is evidence-led: claimant and defendant arguments often diverge on whether a reduction is justified and at what level.
When Smith v Manchester Is Used Instead
Where a claimant has returned to work but faces a handicap on the open labour market, or where residual capacity is too uncertain for a full Ogden calculation, courts may prefer a Smith v Manchester award — typically expressed as a multiple of annual net earnings — rather than a precise multiplicand × multiplier calculation.
Blamire vs Actuarial Approaches for Pension Loss
Pension loss may be quantified actuarially where scheme data supports precision, or by a Blamire-type lump sum where precision is not possible. Defined benefit and defined contribution schemes require different analysis. Pension loss should be coordinated with past and future earnings heads so the overall schedule remains coherent.
Hypothetical worked examples can be added once the current Ogden Tables edition and discount rate have been verified for publication.
FAQ
Ogden Tables and Loss of Earnings — FAQs
Q.01
What are the Ogden Tables in personal injury claims?
The Ogden Tables (Government Actuary's Department actuarial tables) are the standard tool for calculating the present value of future loss of earnings in UK personal injury and clinical negligence proceedings. They provide multipliers — actuarially calculated figures that, when applied to an annual multiplicand (the net annual loss), produce a lump sum representing the present value of future loss over the claimant's working life.
Q.02
What is the multiplier and multiplicand in a loss of earnings claim?
In a future loss of earnings claim, the multiplicand is the annual net loss of earnings — the claimant's annual earnings but for the injury, less actual post-injury earnings. The multiplier is an actuarially calculated figure from the Ogden Tables that reflects the period of loss and the discount rate. Future loss is calculated by multiplying the multiplicand by the multiplier.
Q.03
What is a Smith v Manchester award?
A Smith v Manchester award is a lump sum award for handicap on the open labour market — used where a claimant has returned to work but their injury places them at a disadvantage in the job market. It is used as an alternative to full Ogden Table future loss calculation where the claimant is working but at a competitive disadvantage. It is typically expressed as a multiplier of annual earnings (commonly between 0.5 and 2 years' net earnings), assessed by the court or agreed in settlement.
Q.04
What is the Blamire approach to pension loss?
The Blamire approach to pension loss (from Blamire v South Cumbria Health Authority) is used where it is not possible to calculate pension loss with precision — typically for defined contribution schemes or where the claimant's pension position is uncertain. The court awards a lump sum representing a broad assessment of pension loss. An expert forensic accountant can model the range of pension loss and advise on an appropriate Blamire award figure.
Q.05
What must a CPR Part 35 loss of earnings expert report contain?
Under CPR Part 35 and Practice Direction 35, a loss of earnings expert report must include: the expert's qualifications, a summary of instructions received, the facts and materials relied upon, the methodology applied (including the Ogden Table edition, multiplier, multiplicand, and discount rate where applicable), the expert's opinion and reasoning, a summary of conclusions, and a statement of truth confirming the expert's duty to the court.
