Net Effective Rent
Definition
Net effective rent is the rent a resident actually pays once incentives are averaged in — a free week, a move-in discount, a waived fee — spread across the stay. It is the honest revenue number for modelling and underwriting; headline rent overstates income whenever incentives are routine.
The formula
Net effective rent = (Headline rent × Term − Total incentives) ÷ Term
- Headline rent
- the advertised monthly rate
- Term
- the length of the let in months
- Total incentives
- rent-free weeks, move-in credits, waived fees, referral payments
Worked example
A room advertised at £800 a month on a twelve-month term, with one month rent-free to close.
- 01Gross over the term = £800 × 12 = £9,600.
- 02Incentive = one month = £800.
- 03Net effective = (£9,600 − £800) ÷ 12 = £733.33.
The room is let at £733, not £800. Reported as an £800 let, the rent card looks intact and the 8.3% discount disappears from every report that matters.
Net effective rent matters more in coliving than in conventional letting because the terms are shorter. A one-month incentive spread over a twelve-month tenancy is an 8.3% discount; the same incentive on a six-month coliving stay is 16.7%, which is a different pricing decision wearing the same clothes.
It is also the number that reconciles physical and financial occupancy. If those two diverge by more than a couple of points, the difference is usually sitting in incentives that were never rolled into the reported rate.
Where you need to move a slow room, our own preference is a shorter term at the full rate rather than a full term at a discount. The discount is permanent for the length of the tenancy; the shorter term gives you the room back in a stronger month.
The common mistake
Reporting headline rent while granting incentives
This is the most common way a coliving rent card rots quietly. Each individual incentive feels like a one-off to close a specific room, and none of them appear in the reported rate, so the gap between what the building appears to earn and what it actually earns widens without anyone deciding it should. Report net effective rent from the first incentive, not from the point where somebody notices.
Frequently asked
Is net effective rent the same as achieved rent?+
Close, but achieved rent is often reported without spreading incentives. Net effective rent explicitly amortises every incentive across the term, which is why it is the version to use in pricing decisions and in anything shown to a lender or investor.
Should incentives be shown to residents?+
Whatever you decide, be consistent — a resident who discovers that the neighbour paying the same headline rent received a month free has a fairness problem that outlasts the incentive. In our experience a shorter term at full rate causes fewer of these conversations than a discount does.
