What happens
The app calculates how much of the charge is deductible using a time-weighted split based on your margin debt composition during the billing period.
- The deductible portion is added to capitalized deductible margin interest
- The non-deductible portion is added to non-deductible margin debt
- Both portions increase the margin balance immediately
- No separate Interest Capitalization event is needed for margin interest
Click the event in your ledger to see the full interval breakdown showing how the split was calculated.

Common questions
Is this the same as a credit-line Interest Charge? No. Use Interest Charge for credit-line or HELOC interest. Use Margin Interest Charge for interest charged by your brokerage on margin debt.
Do I need to record a payment or capitalization event? No. Margin interest is added directly to margin debt by this event.
