The landlord's costs — insurance, maintenance, taxes, financing — rise with inflation while the rent stands still, and after several years the gap is substantial without anyone having made a decision.
This shows what the rent would be had it simply tracked inflation since it was set, and how far behind the current figure is. It is a useful starting point for a review, and a fair one to explain to a tenant.
The calculation
Inflation-adjusted rent = original rent × (1 + inflation)^years. Comparing today rent against that figure gives the gap in money terms, and dividing one by the other gives the change in real terms.
Worked example
A rent set at 1,200 five years ago, with average inflation of 3.4%, would be 1,418 today to have kept pace. A current rent of 1,300 is 118 a month below that — about 1,420 a year — and 8.34% lower in real terms than when it was set.
Use it as a starting point, not a demand
Local market rents matter more than inflation when a tenant decides whether to accept a rise or move. Inflation is a fair way to explain why a review is happening; comparable local listings are what make the specific figure persuasive.

Should rent rise with inflation every year?
Not automatically. Rent is set by local supply and demand, and in a weak market it can fall in real terms for years. Inflation tells you what has happened to the value of the rent, not what the market will bear.
What inflation figure should I use?
General consumer inflation for the country is the usual reference. Some landlords use a rental-specific index where one is published, which tracks the relevant market more closely than a basket including food and fuel.
Is a large catch-up increase a good idea?
Rarely in one step. A tenant facing a sudden double-digit rise frequently leaves, and the void plus re-letting costs usually exceed the increase. Phasing it over two reviews normally nets more.
