Prepaid expenses: how they are amortized

Prepaid expenses: how they are amortized

Your company paid the full annual insurance premium in October. If that entire payment goes into October's expenses, the month shows a loss that does not exist and the next nine months look more profitable than they are. Total expense is the same: what changed is the month it is recognized in, and with it the income statement, the ratios and the tax base.

This guide explains what a prepaid expense is, why it is treated as an asset, how monthly amortization is calculated, what happens at year-end and how to control the balance instead of rebuilding it every time. It includes a worked example you can replicate in a spreadsheet and a list of mistakes with their symptoms.

What a prepaid expense is and why it is an asset

A prepaid expense is money that has already left the company for a service that has not been received yet, or that will be received in parts over several months. The classic case is an insurance policy: it is paid today and covers twelve months. The day after payment the company holds a right, not a consumed expense.

That is why it is recorded as an asset. At payment, the prepaid expense account is debited and the bank is credited. Each month a share moves to expense: the expense account is debited and the prepaid account is credited. The asset falls, the expense rises, and profit reflects what was actually consumed.

The test for deciding whether something is a prepaid expense is simple: will the service be received in the future? If the answer is yes and the amount is material, it is an asset. If the service has already been received, it is an expense of the period, even if the invoice arrives later. And if what was paid was an obligation the company already owed, it is a payment, not an asset.

Which items qualify: insurance, rent, licenses, advertising

Any payment whose benefit extends beyond the month it is made in qualifies. It does not depend on the name on the invoice but on the period it covers. These are the items that appear most often in a small business:

How monthly amortization is calculated

The calculation is a division. Take the amount paid, exclude the taxes that are not part of the cost of the service, and divide by the number of months the contract covers. The result is the share charged to expense each month.

Monthly share = amount paid ÷ months of coverage

Three details prevent most mistakes. First, the count starts on the coverage start date, not the invoice date and not the payment date; if the policy runs from October 1 and was paid on September 20, the first month of expense is October. Second, if coverage begins mid-month, prorate by days and that first month carries a smaller share. Third, months of coverage means months of effective service; if the contract includes a grace period without coverage, that month is not amortized.

The amortization month by month, with the account open

With the policy in the example —12,000,000 paid on October 1 for twelve months, October through September— the monthly share is 1,000,000. The table shows how the balance behaves if the contract does not change.

Read the table by columns, not by rows. The monthly expense column always carries the same amount; the accumulated expense column climbs by one million; the balance column drops by one million until it reaches zero in September. That zero is the signal that coverage ended and the subledger must be closed.

First month, year-end close and remaining balance

The first month does two things at once: it opens the expense and it opens the balance. At October 31 the expense is 1,000,000 and the prepaid asset is 11,000,000. At November 30 it is 2,000,000 and 10,000,000. At December 31 it is 3,000,000 of expense and 9,000,000 of balance.

That 9,000,000 is not money lost and not an expense awaiting approval: it is the right to nine months of coverage, January through September of the following year. It appears in the balance sheet as a current asset because it is consumed within the next twelve months. If the policy covered 24 months, the part consumed after one year would be a non-current asset.

The year-end close requires no special entry if amortization was done month by month. It requires two checks: that the subledger balance equals the amount paid minus what has been amortized, and that the months consumed match the months elapsed since coverage began. When the close is done all at once in December, three or four months have to be calculated in one sitting, and that is where the differences appear.

Full example: a 12-month policy and a 24-month license

The same criterion applies to any item. Here are three contracts with different periods, all paid in the last quarter of the year, with the result at December 31.

The license starts on November 1 and runs 24 months: 6,000,000 ÷ 24 = 250,000 per month. By the close only November and December were consumed, that is 500,000, and 5,500,000 remain in the prepaid account to be expensed over the following twenty-two months.

Advertising is the item most often mishandled, because the sales team treats it as a campaign expense. If 18,000,000 was paid in December for three months —December, January and February— the December expense is 6,000,000 and 12,000,000 remain as a prepaid asset. Charging all 18,000,000 to December punishes that month and leaves January and February without the expense they own.

The final check is a sum: 3,000,000 + 500,000 + 6,000,000 = 9,500,000 of expense for the year, and 9,000,000 + 5,500,000 + 12,000,000 = 26,500,000 of prepaid balance. The two totals add up to 36,000,000, exactly what was paid for the three contracts. If that sum does not tie, a month was counted twice or a payment never reached the subledger.

What happens if the contract is cancelled or repriced

A cancellation has three possible outcomes and each one needs a different entry. If the insurer refunds the unused portion, the bank is debited and the prepaid account is credited for that amount: the balance goes to zero and no income is recognized, because there was never an expense to reverse. If the refund is partial, the amount refunded is compared with the balance and the difference goes to expense.

If the contract is cancelled with no refund, the entire balance goes to expense in the month of cancellation. Leaving it in the asset is the most common mistake: the right no longer exists and the asset stays inflated until someone finds it in a review.

If the price changes —a renewal, an endorsement, an add-on— the past is not recalculated. Take the balance pending at the date of the change, add or subtract the adjustment, and divide by the months remaining. The monthly share changes from that month on and the expense already recognized stays as it is. Recalculating everything from the start forces you to reverse closed months and usually ends in a subledger that does not tie to the books.

How it differs from a supplier advance and from inventory

All three are assets, all three are paid before they are consumed, but each one is closed through a different route. Confusing them throws the balance sheet off and, worse, hides commitments.

• Prepaid expense: a service was paid for and is received over time. It closes as the months pass and generates no pending invoice.
• Supplier advance: money was delivered for goods or a service not yet received or invoiced. It closes when the invoice arrives and the goods come in or the service is delivered; if it never arrives, it is a receivable and someone has to chase it.
• Inventory: the goods are already in the warehouse and belong to the company. They become cost when sold, not when time passes. Control is physical and measured in units.

The question that separates the three is what is still missing to close the account. If time is missing, it is a prepayment. If an invoice or a delivery is missing, it is an advance. If a sale is missing, it is inventory.

What is not amortized even though it was paid early

Not every early payment is deferred. Colombian VAT on the invoice is not part of the prepaid asset when the company is liable for the tax and can claim it as a deductible input: it is analyzed separately, under its own conditions, and is not split across the months of coverage. Nor is the part of the service already received before payment deferred; that part is an expense of the period in which it was consumed.

One judgment call remains: if the amount is small and coverage is short, many companies charge it straight to expense. What makes the exception valid is not the amount but the rule: a written threshold applied the same way every month.

How to control it: a subledger per policy or contract

The prepaid expense account needs a subledger per contract, not a single global balance. Every policy, every license and every campaign should have its own line with eight fields: counterparty, contract or policy number, coverage start date, end date, amount paid, monthly share, months amortized and balance.

With those eight fields, control is arithmetic, not memory. At each month-end the sum of the subledger lines is compared with the balance of the main account; if they differ, the error sits in one line, not in the total. Two signals are also reviewed: contracts past their end date with a balance other than zero, and contracts with a zero share for a month.

Control breaks for three recurring reasons: the person who kept the file left and nobody knew where it was, the invoice was filed in a folder without recording the start date, or the payment was booked as expense and the prepaid asset never came into existence. All three are avoided with one mandatory field in the system and a five-minute monthly review.

Effect on the income statement and on tax

On the income statement, a prepayment changes the month of the expense, not its total value. That shift has real consequences: a month carrying the full expense shows a false margin, and the following months show a better margin than they earned. If the company uses those numbers to set prices, to evaluate the sales team or to apply for credit, the decision rests on a distorted picture.

For tax, a company that keeps its books on the accrual basis deducts the expense when it accrues, not when the cheque is written. Paying in December for a policy that covers the following year does not accelerate the deduction: it reduces it to the portion consumed in December. The underlying requirement is the same as for any cost or deduction —a link of cause, necessity and proportionality to the business— and that analysis is done contract by contract. The details of accrual, withholding and deductible input tax depend on the regime and on what the Colombian tax authority (DIAN) requires that year: confirm them with your accountant before closing. Amortization, by contrast, does not move cash: the full outflow shows in the cash flow of the month it was paid.

Common mistakes

These five mistakes show up in almost every review. Each has a visible symptom and a consequence that is paid later.

The underlying pattern is always the same: the month gets fixed and the balance is left with no owner. A prepayment without an owner is an asset discovered late, almost always once the contract has expired and the expense has to be recognized all at once.

An honest close before you decide

Amortizing a prepayment is not a formality. It is the only way the income statement tells the truth about a month. But it demands monthly discipline: if the company closes once a year, the subledger is rebuilt by hand and the effort multiplies.

Nor does it apply to everything. If your prepayments are few and small, per-contract control can cost more than the error it prevents; in that case, a written materiality policy applied with judgment is enough. And if the company is not required to keep books, the recognition criterion should be confirmed with the accountant, because special rules may apply.

What is worth doing without waiting for anyone: treat every prepayment as a right with an expiry date, the same way inventory is controlled. A policy has a start, an end and a balance; inventory has units and cost. Both are checked against a record, not against memory. In Kardex Tauro the payment, the monthly accrual and the prepaid balance sit in the same subledger as the rest of the operation, so the balance is consulted rather than rebuilt at close.
