Enter offering size, total demand, investor demand and IPO price to estimate proportional allocation.
Results are estimates. Actual allocation may change based on investor group, official allocation result and rounding rules.
Proportional allocation formula
- Demand multiple
- Total demand / offering size
- Allocation rate
- Offering size / total demand
- Estimated allocated amount
- Investor demand × allocation rate
- Estimated lots
- Estimated allocated amount / IPO price
- Estimated refund
- Investor demand - estimated used amount
Example proportional allocation calculation
If the IPO size is 1 billion TRY and total demand is 5 billion TRY, the demand multiple is 5x. For a 10,000 TRY investor demand, the allocation rate is roughly 20%, so around 2,000 TRY may be allocated. If the IPO price is 25 TRY, the estimated allocation is 80 lots and the estimated refund is 8,000 TRY.
Frequently asked questions
What is proportional allocation?
Proportional allocation is a distribution method where investors receive shares according to an allocation rate when total demand exceeds the offered amount.
How is demand multiple calculated?
Demand multiple is calculated by dividing total demand by offering size. For example, if demand is 5 billion TRY and the IPO size is 1 billion TRY, the demand multiple is 5x.
Does this tool show the exact IPO lot result?
No. It only provides an estimate. The actual number of lots may change based on official allocation results and investor group rules.
