Rent Leakage in a 30-Bed PG: How Much Is Normal?

Ask a PG owner where the rent is leaking and you usually get a shrug and a story about one bad tenant. So let's do the opposite and build the number from the bottom up, for the kind of building a single owner runs with one or two helpers — 22 to 48 beds — with every assumption on the table so you can argue with it.

On the assumptions below, the answer for a 30-bed PG at ₹9,500 average rent is roughly ₹45,000–₹50,000 a month. That is not the headline cash-not-collected number — that's smaller and more variable. This is the all-in cost of how rent is collected: the float that gets stuck because money arrives on the 12th instead of the 5th, the four evenings the owner spends chasing defaulters, the ₹6,800 here and ₹9,500 there that quietly become write-offs when a tenant disappears.

Treat it as a model, not a measurement: it moves a lot with how late your tenants actually run. The point isn't our number, it's that most owners have never added these three buckets up at all — so whatever their real figure is, it's invisible.

The three buckets

Rent leakage in a small PG decomposes pretty cleanly into three things. We'll do the math for a hypothetical-but-realistic 30-bed PG at ₹9,500 average rent — total billing ₹2,85,000/mo.

1. Working capital tied up in late payment — ~₹22,000/mo

Assume rent lands on average around the 11th against a 5th due date — a six-day weighted average delay across the building. On ₹2,85,000 monthly billing, with money costing the owner ~12% a year (a realistic cost of working capital for an owner funding the gap on a personal OD line at 14%):

₹2,85,000 × 12% × (6 / 365) = ₹562/mo in pure interest cost — small, and that part is simple arithmetic. The real damage is structural: when 30% of rent arrives after the 10th, the owner ends up using a personal OD to pay the cook's salary, the electricity bill, and the cleaning vendor. The OD sits drawn for half the month, every month. The interest and the once-a-year “processing fee” on that drawdown run to roughly ₹21,000-₹24,000 a year on their own — and the larger cost is what permanently borrowed working capital does to every other decision: the repair you defer, the empty bed you don't repaint, the supplier rate you accept because you need the credit.

2. Time spent on dunning — ~₹17,000/mo

In a small PG the owner does this themselves. Assume 11 hours a month on rent follow-up — about an evening a week: copy-pasting WhatsApp reminders, walking up to rooms, calling parents, accepting partial cash, writing in a notebook, ticking off a Google Sheet later.

If you value the owner's time at even ₹400/hr (well below what they'd earn doing literally anything else productive with that evening), that is ₹4,400/mo just in opportunity cost. Add the emotional tax of being a debt collector to people you just made dinner for — the part of the job owners tell us they like least — and you can see why so many would hand it to a ₹15,000-a-month helper if they could find one they trusted. Most don't. So the cost is real, but unbooked.

3. Slow-burn write-offs — ~₹8,000/mo

This is the one nobody tracks. The tenant who leaves owing 8 days of rent. The deposit that was ₹9,500 but the exit damage was ₹12,000. The friend-of-a-friend who paid ₹500 less “just this month” for fourteen consecutive months.

Annualised, a couple of bad exits plus the quiet standing discounts land somewhere between ₹85,000 and ₹1.1L a year for a 30-bed building — call it ₹8,000/mo. The variance is high because one bad exit can blow up a year's number. Almost nobody carries a line-item for this in their books, which is exactly why it stays invisible.

“You know you lose some money. You don't know you lose a Royal Enfield every year.”

— Why nobody spots it

What actually moves the number

Four things move this number. Here they are, ranked by how much they shift it on the model above — not by how interesting they are.

Intervention 1 — Pre-due WhatsApp nudge (3 days before)

The single highest-impact thing. A non-aggressive, before-the-due-date message: “Hi Rahul, your May rent of ₹9,500 is due on the 5th. Pay link: ... You'll get a receipt instantly.”

Pull the weighted-average payment date from the 11th to the 7th and roughly ₹14,000 comes off the monthly number in the model — almost entirely from the working-capital bucket. The reason it works isn't magic: most late payers aren't deadbeats, they're forgetful. The pre-due nudge gives them a 3-day window where paying is the path of least resistance.

Intervention 2 — Accept partial payments, visibly

Counterintuitive. Most owners refuse partial because “they'll never pay the rest.” The logic runs the other way: a tenant who can put ₹6,000 of ₹9,500 down on the 5th, but is forced into all-or-nothing, pays ₹0 until the 12th. Take the ₹6,000 and you have pulled two-thirds of that bed's rent forward by a week.

The trick is to show the running balance in the WhatsApp receipt: “Received ₹6,000. Balance: ₹3,500. Next reminder: 8th May.” A specific, finite number gets cleared; “some rent” gets deferred. Net impact in the model: about ₹9,000/mo.

Intervention 3 — Right-priced deposit

Most operators charge a flat 1-month deposit. The write-off bucket almost entirely comes from exits where the deposit didn't cover the unpaid rent + damage. For ₹9,500 rent buildings serving working professionals, the math says 1.5 months is the right number; for student-heavy buildings, 2 months. Move to 1.5 months at renewal and it is the write-off bucket that shrinks — halve it and that is worth ~₹4,000/mo. In practice the deposit is rarely what makes a good tenant leave; the quoted rent is.

Intervention 4 — Public defaulter list (controversial)

Some operators run a printed sheet near the entry of the building showing names with outstanding dues > 10 days. It works — public shame usually does. It is also, frankly, ugly, it costs you the goodwill of every tenant who reads it, and we don't recommend it.

A softer version: a private WhatsApp group with the tenant and their listed emergency contact (usually a parent), used only after 15 days overdue. Same dynamic, less collective shame. Worth maybe ₹2,000-₹3,000/mo and you keep your soul.

What we won't pretend

We've left out the impact of evicting persistent defaulters. Most small owners are reluctant to escalate even when the law and the agreement are clearly on their side, so a model that leans on it would be modelling something that doesn't happen. That's a separate post, and a harder one.

We also ruled out anything coercive — tying door access or utilities to dues, that kind of thing. It isn't the relationship we want between an owner and a resident, and it isn't what we'll build. The numbers above suggest you don't need it.

If you want to run these numbers for your own building, we built a calculator on the homepage that does it in 30 seconds. Plug in your bed count, rent, and average days-to-pay; you'll get your own version of this number, which is the only one that matters.
