Split Multipliers

How to use this calculator

Applies the "splitting the multiplier" method at ¶¶42-53 of the Ogden guidance, where losses vary across different future periods. Give the Claimant's personal details, the entire period of the losses, and then the dates and multiplicands for each distinct period.

Ogden Tables 8th Edition guidance notes ¶42–53 — variable future losses across sub-periods of a whole loss window.

Whole period

Lifetime (DOB + sex) — Table 1 (male) or 2 (female) Fixed period (years) — Table 36

Age handling

Ogden practice is to use age last birthday at the assessment date. Linear interpolation between adjacent integer ages is more accurate but non-standard — match the Multiplier Getter's Interpolation tab if you need it.

Tables A–D reduction factor (optional)

Look up an Ogden Tables A–D reduction factor for contingencies other than mortality. Resolved values can be applied to all rows in one click, or used to inform manual per-row entries. Per-row RF entries override anything applied here.

Sex

Disability

Employment status

Education

Age (16–54)

Suggested RF: —

Source: Ogden Tables 8th Ed. — Tables A (men, non-disabled), B (women, non-disabled), C (men, disabled), D (women, disabled). Age range 16–54 only; outside this range, no reduction factor is recognised by the published tables.

Sub-periods

To run the final sub-period to the end of the claimant's life (lifetime mode) — or to the end of the fixed period — leave that last row's “End” cell blank. The calculator fills the remaining multiplier automatically.

Each row's Start and End can be entered as years from the start of the whole period (default) or as calendar dates — toggle with the small button to the right of each row's Start cell. Mix modes within one claim. RF = optional reduction factor (decimal, e.g. 0.85) — populate manually, or use the Tables A–D lookup above. Negative or zero multiplicands are allowed (e.g. saved expense).
