How M1 Margin Loan interest is calculated and charged

Updated this week

This guide explains how interest is calculated and charged for M1 Margin Loans. Learn how daily interest accrues, how it's billed each month, and what happens if you don’t have enough cash in your account to cover interest.

How is margin loan interest calculated?

  • Interest accrues daily: You only pay interest on the days you have a margin loan balance.

  • Daily interest rate: The annual interest rate is divided by 360 to get the daily rate.

Example: M1 Margin Loan interest calculation

  • If your interest rate is 5.65%, your daily rate is 0.0156944% (5.65% ÷ 360).

  • If you borrow $10,000, the daily interest is $1.57 ($10,000 × 0.0156944%).

  • For a month with 30 days, the interest charged would be $47.10 ($1.57 × 30).

How is margin loan interest charged?

M1 deducts the previous month’s interest automatically on the third trading day of the following month, before the morning trade window, in this order:

  1. Cash balance: Interest is taken from your available cash in the account associated with your Margin Loan.

  2. Increase Margin Loan: If cash is insufficient and you have available margin, your Margin Loan balance will increase to cover the interest charge.

  3. Sell Investments: If steps 1 and 2 aren't possible, M1 will sell investments in your account to cover the interest payment.

Reviewing your margin loan interest charges

Your Margin Loan statement will be available at the end of each month. You can find it under “Bills” on your Margin Loan dashboard.
