Examples
A trailer loan draft splits two ways
You run a landscape crew. On August 12, the bank auto-drafts $684.50 from checking for your dump-trailer loan. The August coupon splits it: $519.00 principal and $165.50 interest. In QuickBooks Online or Xero, split the bank-feed line: reduce the loan $519.00 and code $165.50 to interest expense. That $165.50 is the charge for using the borrowed money this month; the $519.00 is not an expense.
The whole ACH is not the charge
Your auto-body shop's January 7 bank feed shows a $1,246.00 ACH to an equipment lender for the paint-booth loan. You match the whole $1,246.00 to interest expense because the payee looks like a finance company. Only $218.60 of that draft is the charge; $1,027.40 is principal. Recode the split in QuickBooks Online or Xero so January profit is not short $1,027.40 and the loan on the balance sheet actually pays down. Check the lender coupon before you accept the bank-feed category.
Why it matters
Interest is the cash charge for using borrowed money: an expense when you pay it on a loan, line of credit, or card, and income when a bank or customer pays it to you. If you have financing, you will see it on most monthly statements and at every close; if you do not borrow, it stays quiet until you take a loan or earn it on a deposit. Split each payment so only the charge hits the P&L and the rest pays down principal on the balance sheet; dump the whole draft into expense and profit looks worse while the loan never shrinks. Treat an owner draw or a share of the company as interest and you invent an expense that is really equity, and do not confuse this cash charge with imputed interest, which is an assumed return on capital.
