Rent Increase Calculator

New rent, percentage rise, yearly cost and start date after notice.

About this tool

Enter the current monthly rent and the increase as a percentage, an amount or the new rent. Add an inflation figure to compare against, the date notice is given and the notice period. You'll see the new rent, the rise per month and per year, the percentage change and the earliest date it can start.

Understanding a rent increase

Rent rises are easier to discuss with clear numbers. A 5% increase on ยฃ1,200 a month is ยฃ60 more a month, or ยฃ720 a year, taking the rent to ยฃ1,260. Comparing that with inflation shows whether it's keeping pace with rising costs or going further. Tenants can also check local listings to see whether the new rent is in line with similar homes. How and when rent can go up depends on where you live and on your tenancy. In England, private landlords can generally increase rent once a year with at least two months' notice, using a Section 13 notice, and tenants can challenge an increase they think is above market rent at the First-tier Tribunal. Scotland has its own notice rules and rent adjudication. Wales uses a set notice period for occupation contracts. Many US states and cities, and other countries, set notice periods, frequency limits or caps, and fixed-term contracts may contain their own review clause. If you're a tenant, reply in writing, ask how the figure was set and keep records. If you're a landlord, giving a clear explanation and reasonable notice keeps good tenants. Honest limits: this doesn't check the law for your area, and notice rules count from when the notice is received, not sent. This isn't legal advice. The rent affordability calculator, the rent split calculator and the inflation calculator are related.
