Void period calculator

Every empty week costs you more than just lost rent. Council tax kicks back to you, utilities keep ticking, and re-let fees stack up. See exactly what your voids are costing — and what cutting them in half would save you.

Enter your property and your typical void pattern. We’ll calculate your annual void cost, what each empty week is really costing you, and how much you’d save by reducing voids. Defaults are sensible UK BTL averages — tweak anything to match your situation.

The property

Property value lets us calculate yield drag — what voids are doing to your return on investment.

Your void pattern

UK average is 3–4 void weeks per turnover, 1 turnover per year. HMO/student lets often run 0.5–1 turnover, family lets every 2–3 years.

Holding costs (during void)

Council tax usually falls on the landlord when the property is vacant for more than 7 days. Some councils charge premiums — check your local rate.
