Ogden tables

Ogden tables is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ogden tables rather than just read about it. In short: The Ogden tables are a set of statistical tables and other information for use in court cases in the UK. Their purpose is to make it easier to calculate future losses in personal injury and fatal accident cases.

Key takeaways

  • Ogden tables belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ogden tables to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ogden tables from memory before moving on to harder problems.

Reference excerpt

The Ogden tables are a set of statistical tables and other information for use in court cases in the UK. Their purpose is to make it easier to calculate future losses in personal injury and fatal accident cases. The tables take into account life expectancy and provide a range of discount rates from -2.0% to 3.0% in steps of 0.5%. The discount rate is fixed by the Lord Chancellor under section 1 of the Damages Act 1996. Effective 11 January 2025, this rate increased from -0.25% to 0.5% in England and Wales. The discount rate in both Scotland and Northern Ireland had already been set at 0.5% following reviews by the Government Actuary's Department, effective 26 September 2024. The full and official name of the tables is Actuarial Tables with explanatory notes for use in Personal Injury and Fatal Accident Cases, but the unofficial name became common parlance following the Civil Evidence Act 1995, where this shorthand name was used as a subheading – Sir Michael Ogden QC having been the chairman of the Working Party for the first four editions.

History The tables were first published in 1984. Section 10 of the Civil Evidence Act 1995 authorised their use in evidence in the UK "for the purpose of assessing, in an action for personal injury, the sum to be awarded as general damages for future pecuniary loss". They were first used by the House of Lords in Wells v. Wells in July 1999. The 7th edition of the tables made changes to the discount rate range (previously 0.0% to 5.0% revised to -2.0% to 3.0%) to allow for a revision of the rate by the Lord Chancellor (currently under consideration as at 24 October 2011) and to provide for the implications of the case of Helmot v. Simon. The 8th edition was published in 2020 and updated in August 2022.

Using the Ogden tables There are 28 tables of data in the Ogden Tables. Table 1 (Males) and Table 2 (Females) are for life expectancy and loss for life. Tables 3 to 14 are for loss of earnings up to various retirement ages. Tables 15 to 26 are for loss of pension from various retirement ages. Table 27 is for discounting for a time in the future and Table 28 is for a recurring loss over a period of time.

How to calculate life expectancy To calculate life expectancy, you need to use Table 1 (for males) or Table 2 (for females) and use the data in the 0% column. So for a 45 year old female, using Table 2 you would look down the first column to find 45 and then across to the 0% column which gives a figure of 43.93. In cases where the age is not a whole number, i.e. female who is 45.75 years, then you use the figure for 45 years (43.93) and the figure for 46 years (42.87) and interpolate between the two (46-45.75) x 43.93 + (45.75-45) x 42.87 to give 43.14 years.

How to calculate multiplier for lifetime loss If the claimant is to suffer a loss that will last their entire life, you need to use Table 1 (for males) or Table 2 (for females) and use the data in the 2.5% column. So for a 50-year-old male, using Table 1 you would look down to first column to find 50 and then across to the 2.5% column which gives a figure of 22.69.

How to calculate value of a single loss in the future If the claimant needs to pay for something in the future, then the present value can be worked out using Table 27. Look up the period in the future in the first column and then across to the 2.5% column for the multiplier. For example, a purchase required in 10 years time would need to multiplied by 0.7812.

How to calculate multiplier for loss over a period If the claimant has a recurring loss over a period of say 15 years, then use Table 28 looking up 15 in the first column and then across to the 2.5% column which gives a multiplier of 12.54. If the loss does not start until some time in the future, then you can combine Table 27 and Table 28 to give an overall multiplier. For example a loss over a period of 15 years that starts in 10 years time would have a Table 27 multiplier of 0.7812 and a Table 28 multiplier of 12.54 giving an overall multiplier of 9.80.

Worked examples

Example 1 — a first encounter with Ogden tables

Start with the simplest possible case. Write down what Ogden tables claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ogden tables before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ogden tables ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ogden tables

In research
Ogden tables appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ogden tables in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ogden tables is common in secondary-school and first-year university syllabi. It links to neighbouring topics Actuarial science, Forensic statistics, Medical malpractice, so understanding it makes those chapters shorter.
In everyday life
Look for Ogden tables outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
