Quick answer
Long-term debt is a borrowing obligation with contractual amounts due beyond the current-classification horizon. A note payable documents a promise to repay principal, usually with interest. A long-term loan may also have a current portion, and each payment may include both interest expense and repayment of principal.
A cash borrowing provides funds in exchange for contractual payments later. Debt can also arise through a non-cash acquisition or refinancing. The balance sheet reports the unpaid obligation; the income statement reports borrowing cost as time passes; and the cash flow statement separates the cash received and repaid from the interest classification required by the applicable framework.
Principal, interest, and carrying amount
Principal is the amount contractually repayable. Interest is the cost of financing over time. The carrying amount is the amount reported for the liability after applying the required measurement method. Those amounts can differ when fees, discounts, premiums, or other adjustments are present.
Amortized cost starts with the initial measured amount and updates it for financing cost and payments. For a simple note issued at principal with no fees, discount, or premium, it tracks unpaid principal. Period interest = opening principal × interest rate for that period. Principal repaid = payment − interest. Closing principal = opening principal − principal repaid. More complex instruments can make carrying amount differ from principal.
Under ASPE Section 3856, an arm’s-length financial liability normally begins at fair value, with directly attributable fees and costs included when it will not later be measured at fair value. Related-party liabilities use separate cost-based rules. Subsequent measurement then follows the Section’s applicable cost, amortized-cost, or fair-value requirement rather than the debt’s label alone.
Current and non-current presentation
Calling a borrowing “five-year debt” does not make every dollar non-current. The portion due within the applicable current-liability horizon may be shown separately from the remainder. Under ASPE Section 1510, a qualifying long-term obligation presents the next-year portion as current and the remainder as long term. That classification is based on reporting-date facts rather than expected refinancing, and creditor demand rights or covenant breaches can change the conclusion under the Section’s specific provisions. IFRS uses its own reporting-date rights analysis under IAS 1 or IFRS 18 for the applicable period.
Amortize a five-year instalment note
On January 1, 2026, Coastline Services borrows $50,000 under a five-year note bearing 8% annual interest. Equal payments of $12,522.82 are due each December 31. The schedule displays whole dollars but calculates with unrounded amounts, and the note is measured at amortized cost under the stated facts.
Each $12,522.82 payment covers interest and principal. As the outstanding balance falls, less of the fixed payment covers interest and more repays principal.

Each year’s interest is the opening carrying amount multiplied by 8%. The rest of the payment reduces principal.

| 2030 | $11,595 | $928 | $12,523 | $11,595 | $0 |
Because the calculation uses unrounded balances, recomputing a row from the displayed whole-dollar amounts can produce a $1 difference.

After the payment, the note’s carrying amount is $41,477. Only $4,000 is a 2026 expense; the $8,523 principal portion removes part of an existing liability.

At December 31, 2026, the next payment contains $9,205 of principal. The current portion is the principal due within the applicable short-term horizon; the interest in the next payment is not part of the debt balance. Assuming the governing classification requirements are met, the $9,205 is current and the remaining carrying amount is non-current. If Coastline reports before a payment date, it accrues interest for the time elapsed rather than waiting for cash to move.

- Covenants and whether the entity complied with them at the reporting date.
