Understanding PAR (Portfolio at Risk) and Loan Aging

Understanding PAR (Portfolio at Risk) and Loan Aging
In short: Portfolio at Risk (PAR) is the share of your loan book that is overdue — the outstanding balance of loans with a payment past due, divided by your total outstanding portfolio. PAR30 (loans more than 30 days late) is the standard health metric. Loan aging sorts overdue loans into buckets (1-30, 31-60, 61-90, 90+ days) so you see trouble building before it becomes a loss.

Every lending business lives or dies by one question: will the money come back? Revenue looks great until borrowers stop paying, and by the time missed payments show up in your bank balance, it is often too late to act. Portfolio at Risk and loan aging are the early-warning instruments that tell you the truth about your book — today, not next quarter.

What Portfolio at Risk measures

PAR answers a precise question: how much of my outstanding money is attached to borrowers who have fallen behind? It is expressed as a percentage. The numerator is the outstanding principal balance of every loan that has at least one payment overdue past a chosen threshold; the denominator is your total outstanding portfolio. Crucially, PAR counts the whole outstanding balance of a late loan, not just the missed installment — because a borrower who missed one payment is a risk on the entire remaining balance.

PAR captures the full outstanding balance of every late loan as a share of the total book.

How to compute PAR — an example

Suppose your total outstanding portfolio is ₱1,000,000. Three borrowers with a combined outstanding balance of ₱80,000 are more than 30 days late on a payment. Your PAR30 = ₱80,000 ÷ ₱1,000,000 = 8%. That single number tells you, at a glance, that 8% of your money is exposed to borrowers who are already behind — a figure you can track week over week to see whether your book is getting healthier or sicker.

PAR uses the outstanding balance, not the number of loans. Ten tiny late loans matter less than one large one — and PAR, weighted by peso balance, reflects that correctly.

Loan aging: seeing trouble build

PAR gives you one headline number; loan aging gives you the story behind it. Aging sorts your overdue loans into time buckets by how far past due they are. The further right a loan sits, the less likely you are to recover it — which is why watching loans move between buckets is so powerful. A loan drifting from the 1-30 bucket into 31-60 is a signal to act now, while recovery is still realistic.

A typical aging schedule
Aging bucketMeaningRecovery outlook
CurrentNo payment overdueHealthy
1–30 daysJust slipped past dueUsually recoverable — act early
31–60 daysFalling behindAt risk — intensify follow-up
61–90 daysSeriously delinquentDoubtful — escalate
Over 90 daysLong overdueLikely loss — consider provision/restructure
Each step to the right lowers the odds of recovery. Watch loans move between buckets.

Why aging drives action, not just reporting

The point of aging is not a pretty report — it is a to-do list. Loans in the 1-30 bucket need a friendly reminder. Loans in 31-60 need a phone call and a plan. Loans past 90 days may need restructuring or a provision for bad debts. Aging also feeds directly into your financial statements and your SEC compliance, because provisioning for doubtful accounts is grounded in exactly this data.

Using PAR and aging every week
1
Refresh PAR and aging
Recompute where every overdue loan sits, ideally in real time rather than at month-end.
2
Work the youngest buckets first
A quick nudge on a 1-30 loan prevents a 61-90 problem.
3
Escalate the older buckets
Phone calls, field visits, or restructuring for loans drifting toward 90 days.
4
Provision the losses honestly
Recognize doubtful accounts so your statements reflect reality.
PAR tells you how big the problem is; aging tells you exactly which loans to work today.

PAR alongside your other portfolio metrics

PAR is powerful but it is one gauge, not the whole dashboard. Read it alongside a few companions. Your collection rate — the share of amounts due in a period that you actually collected — tells you how well current-month collections are going, while PAR tells you how much risk has accumulated. Your write-off ratio — loans written off as uncollectible against the portfolio — shows what PAR eventually turned into. And portfolio yield — interest and fees earned against the portfolio — tells you whether the returns justify the risk you are carrying.

Watched together, these numbers keep you honest. A lender can post a beautiful yield while PAR quietly climbs, because aggressive lending inflates both income and risk at once. Only by reading PAR and the write-off ratio next to yield do you see whether growth is healthy or whether you are simply booking interest you will later have to write off. The discipline is to review them as a set, on the same cadence, so no single flattering number hides a problem the others would reveal.

Real-time PAR beats a month-end surprise

The danger with manual tracking is lag: if you only compute PAR at month-end, you learn about a delinquency spike weeks after you could have acted. LendKoPH computes PAR and full loan aging from your live collection records, so you always see who is due, who is late, and by how many days — the way examiners expect, and the way that lets you save loans before they turn into losses.

Frequently asked questions

What is Portfolio at Risk (PAR)?

The outstanding balance of loans that have a payment overdue past a threshold, divided by your total outstanding portfolio, expressed as a percentage. PAR30 (loans over 30 days late) is the industry standard.

Does PAR count the missed installment or the whole loan?

The whole outstanding balance of the late loan. A borrower who missed one payment is considered a risk on their entire remaining balance.

What is loan aging?

Sorting overdue loans into buckets by how far past due they are — typically 1-30, 31-60, 61-90, and over 90 days. The further right a loan sits, the less likely you are to recover it.

What is a healthy PAR?

Targets vary by lending model, but many lenders aim to keep PAR30 at or below about 5%. The key is tracking the trend over time, not just the single number.
