Understanding Pro-Rata Value Calculations

ALTIVOSponsor Management

How Altivo calculates the suggested value on an allocation - the five formulas, worked examples, and how it relates to what you actually agree with a sponsor.

Allocations > Pro-Rata Value

Pro-rata, agreed, and discount

The pro-rata value is Altivo's calculated fair value for an allocation, based on the asset's price, its duration type, the dates, and the units. The agreed value is what you and the sponsor actually settled on. The discount is the difference between them, floored at R0.

The five formulas

Duration typeFormulaExample (1 unit)
Per weekprice × units × (days / 7)R500/wk × 1 × (122/7) = R8,714.29
Per monthprice × units × (days / 30.44)R2,000/mo × 1 × (303/30.44) = R19,908.02
Per yearprice × units × (days / 365)R24,000/yr × 1 × (184/365) = R12,098.63
Once-offprice × units - dates ignoredR5,000 × 1 = R5,000.00
Per eventprice × units - dates ignoredR1,000/event × 3 events = R3,000.00

30.44 is the average number of days in a calendar month (365 ÷ 12). The calculation always uses exact calendar days between your start and end date, never rounded months or weeks - which is also why a duration-type mismatch on an asset produces a plausible-looking but wrong number rather than an obviously broken one. See "Managing Assets" for what to check if a suggested value looks off.

Unpriced assets

If an asset has no price set, no value is suggested - the field is left blank and fully editable, with no pencil-unlock step needed.

Frequently asked questions

The value is slightly different from my own calculation.

Altivo uses exact calendar days, not rounded months. A six-month allocation is calculated on the real number of days between the two dates, not on 6 × 30.

Can I change the suggested value?

Not directly - it is always calculated and read-only. Click the pencil icon to unlock the agreed value and enter your own figure; the discount updates automatically to show the gap between the two.

I changed the asset's price. Do existing allocations update?

No. An allocation's values are fixed at the point it was created or last edited. Changing the asset's price only affects allocations made after the change.

Why 30.44 instead of 30 for monthly calculations?

It is the true average - 365 days divided by 12 months. Using a flat 30 would undercount by roughly half a day every month, which compounds over longer allocations.

The suggested value looks completely wrong, not just slightly off.

This almost always means the asset's duration type does not match reality - a once-off event wrongly set to per year, or the reverse. Fix the duration type on the asset itself; the suggestion will follow.
