Who this is for

Amount and timing have different owners

The percentage calculator subtracts current rent from proposed rent, divides by current rent and multiplies by 100. Annual impact multiplies the difference by 52 weekly or 12 monthly payments. It does not determine notice validity.

Worked example

Illustrative scenario

An increase from 500 to 550 for the same period is 10%. A notice-period comparison asks a separate question and cannot convert that percentage into a legal verdict.

A timing comparison

This resource and the amount calculator do not assess notice procedure. Notice timing, forms and challenge routes depend on your local jurisdiction; consult its current official guidance.

Frequently asked questions

Does the result decide my application or legal position?

No. It reports scoped arithmetic or source guidance. Your agreement, the recipient's assessment and applicable exceptions remain separate.

Are my entered figures sent with analytics?

The calculation runs in your browser. If you allow analytics, pseudonymous usage events contain the tool, market and an ephemeral attempt ID, not your amounts, documents or individual result.
