Recording loans correctly: principal, interest, and why proceeds aren't income
Loan proceeds are a liability, not revenue, and every payment splits between interest expense and principal reduction per the amortization schedule. The entries, and the two errors that wreck a year of books.
Two rules cover almost everything about loans in the books. First: proceeds are a liability, not income — the money is not yours, so it never touches revenue. Second: every payment splits between interest (an expense) and principal (a reduction of the liability), in proportions that change every month per the amortization schedule. Every common loan-bookkeeping disaster is a violation of one of these two.
Funding day
A business borrows 50,000:
| Account | Debit | Credit |
|---|---|---|
| Cash | 50,000 | |
| Loan payable | 50,000 |
Assets up, liabilities up, profit untouched. Borrowing makes you no richer.
If the lender nets out an origination fee — you receive 48,750 on a 50,000 note — record the full liability and put the fee where it belongs (commonly amortized over the loan's life; for a small short loan, many books expense it, a judgment worth a preparer's nod):
| Account | Debit | Credit |
|---|---|---|
| Cash | 48,750 | |
| Loan fees (asset or expense per policy) | 1,250 | |
| Loan payable | 50,000 |
The monthly payment, per the schedule
Say the payment is 966 monthly on the 50,000 at 6% over five years. Month one, the schedule says 250 of interest and 716 of principal:
| Account | Debit | Credit |
|---|---|---|
| Interest expense | 250 | |
| Loan payable | 716 | |
| Cash | 966 |
Never guess the split — read it off the lender's amortization schedule. By the final year the same 966 is mostly principal.
The liability account absorbs the funding and shrinks with every principal portion:
Loan payable
| Debit | Credit |
|---|---|
| Month 1 principal716 | Loan funded50,000 |
| Month 2 principal719 |
Balance after two payments: 48,565 — which must match the lender's statement.
Why the split matters to profit. Only the interest is an expense; principal repayment is returning someone's money.
Illustrative 50,000, 6%, 5-year amortization; annual payment total 11,592 both years.
The two classic wrecks
- Whole payment to expense. Profit is understated by the year's principal — and the loan balance never falls, so the balance sheet shows debt you no longer owe. Cousin error: proceeds booked as income, overstating profit by the whole loan. Both connect to the broader point that cash movement is not income.
- Whole payment to principal. Profit is overstated by the year's interest, and the loan account goes negative years early.
The repair is one entry at reconciliation: compare your Loan payable to the lender's year-end statement, and rebalance the difference between Interest expense and Loan payable.
What to do next
- Get the amortization schedule for every open loan; file it with the books.
- Set the payment split in your software as a recurring split transaction, updated from the schedule.
- Reconcile each Loan payable account to the lender's statement at year-end — your preparer needs the interest total anyway.
Frequently asked questions
- Are loan proceeds income?
- No. Borrowed money is a liability — you owe it back — so the entry debits Cash and credits Loan payable, touching neither revenue nor profit. Booking proceeds as income overstates revenue and taxable profit by the full loan amount, one of the most expensive routine bookkeeping errors.
- How do I split a loan payment between principal and interest?
- Use the lender's amortization schedule, which lists each payment's interest and principal portions. Debit Interest expense for the interest, debit Loan payable for the principal, credit Cash for the full payment. The split shifts every month — early payments are mostly interest — so a fixed split is always wrong.
- Why doesn't my loan balance in the books match the lender's statement?
- Usually because payments were posted entirely to expense or entirely to principal instead of split per the schedule. Reconcile the ledger's Loan payable to the lender's year-end balance and post a correcting entry for the difference between interest expense and principal reduction.
