Fund subscription amount, fee, and units
How many fund units do your subscription payment and offering-period interest purchase after fees?
When to use it and why it works
The payment includes both money invested and a sales fee. Under this fee convention, the rate applies to the net investment. Divide by one plus the fee rate, add interest eligible for conversion, then divide by initial unit value.
Net = amount / (1 + fee rate); fee = amount − net; units = (net + interest) / initial unit value
Work through an example
Subscribe 10,000 at a 1.2% fee, with interest of 5 and initial unit value of 1. Find the net amount, fee, and units.
Read this example’s explanation
Net investment is about 9,881.4229 and the fee 118.5771. Add 5 and divide by 1 for about 9,886.4229 units, using the unrounded net amount.
Your calculated answer
- Net subscription amount
- 9,881.42
- Subscription fee
- 118.58
- Theoretical subscription units
- 9,886.4229
Follow each step
Divide the total payment by one plus the fee rate to obtain the net investment.
10000 / (1 + 1.2 / 100) = 9,881.4229249Subtract the net investment from the total payment to find the fee.
10000 − 9881.4229249 = 118.5770751Add eligible interest to the net investment, then divide by initial unit value.
(9881.4229249 + 5) / 1 = 9,886.4229249
Intermediate calculations retain precision; displayed values are rounded. Follow the precision requested by your question.
What the result means
Net investment plus fee must equal the payment. Units are a quantity, not money. Working precision is retained here; the prospectus and registrar determine actual rounding and confirmed units.
Mistakes to watch for
- Do not multiply the gross payment by the rate: this fee convention uses the net investment as its base.
- Add offering-period interest only once. Use the product’s subscription terms and initial unit value, rather than importing an unrelated purchase NAV.
- Fee tiers, fixed fees, channel discounts, and intermediate rounding are not modeled. Displayed values are not transaction confirmations.

Set up the formula first. Answers rounded to two decimals are accepted; use six decimals for absolute values below 0.01. For percentages, enter the number before the percent sign.
How to use this calculator
