This article explains how Altivo calculates pro-rata values for allocations. It covers the five formula variants (per week, per month, per year, once-off, per event), worked examples for each, and explains the relationship between pro-rata value, agreed value, and discount.
Allocations > Pro-Rata Value
The pro-rata value is the calculated fair-market value of an allocation based on the asset's price, duration type, allocation period, and units allocated. The agreed value is what the school and sponsor actually agree. The discount is the difference (pro-rata minus agreed, minimum R0).
| Duration type | Formula | Example (1 unit) |
|---|---|---|
| Per week | price x units x (days / 7) | R500/wk x 1 x (122/7) = R8,714.29 |
| Per month | price x units x (days / 30.44) | R2,000/mo x 1 x (303/30.44) = R19,908.02 |
| Per year | price x units x (days / 365) | R24,000/yr x 1 x (184/365) = R12,098.63 |
| Once-off | price x units (no time calc) | R5,000 x 1 unit = R5,000.00 |
| Per event | price x units (no time calc) | R1,000/event x 3 events = R3,000.00 |
Note: 30.44 is the average days per calendar month (365 / 12). The calculation uses exact calendar days, not rounded months.
If an asset has no price set (null), no pro-rata value is calculated and the suggested value field is left blank. The agreed value field is fully editable with no suggestion shown.
Altivo uses exact calendar days, not rounded months or weeks. A six-month allocation is calculated on the actual number of days between the start and end date, not on 6 x 30 = 180 days.
No. The pro-rata value is always system-calculated and read-only. You can change the agreed value using the pencil unlock button, and the discount adjusts automatically to reflect the difference.
Existing allocations keep their original pro-rata and agreed values. Price changes on the asset only affect future allocations created after the change.
30.44 is the average number of days per calendar month (365 / 12). Using 30 would undercount by about half a day per month. Using 30.44 gives a more accurate fair-market value over the actual allocation period.
