What does that rent increase really cost?
Enter current and proposed rent to calculate the percentage change, the difference per payment period and the annual difference. The calculator provides figures only; it does not assess whether an increase is permitted or recommend how to respond.

Common questions
How do I work out a rent increase percentage?
Subtract current rent from proposed rent, divide the difference by current rent, then multiply by 100. The calculator also converts the difference to the selected payment period and an annual figure.
Is my landlord allowed to increase the rent?
The rules depend on your tenancy type and location. Fixed terms, notice periods and formal processes differ by country and region. This calculator shows the cost of the change. Check your agreement and current official guidance to understand what is permitted.
Should I accept the increase or move?
The calculator does not recommend whether to stay, move, accept or negotiate. It supplies the percentage and annual difference for your own comparison; your costs, tenancy terms, alternatives and local rules are outside its calculation.
Can I negotiate a proposed increase?
Whether and how you can respond depends on your tenancy, the applicable rules and the parties involved. The calculator can provide figures to refer to, but it cannot predict an outcome. Check your agreement and current official guidance.
