The rent, deposit and notice rules in your state, as numbers.
Interest owed on a security deposit, the most a landlord can raise rent, the biggest late fee the law allows, and the date a notice actually takes effect. Each calculator applies the statute for your state or city and links to it.
Security deposit interest calculator
Sixteen states and cities require landlords to pay interest on deposits. Pick the jurisdiction, enter the deposit and dates, and the calculator applies that year’s published rate and the local rules on thresholds and administrative deductions.
Current deposit interest rates
Rent increase limits
Three states and seven cities or counties cap annual rent increases with a published formula. These are the figures in force now; the rent increase calculator turns them into a maximum new rent and the notice period you need.

Why these numbers change every year
Most of the figures on this site are not fixed in statute. Connecticut’s deposit index, Chicago’s deposit rate, Maryland’s Treasury-linked rate, every rent cap tied to inflation and every Rent Guidelines Board order are republished on a schedule, and most competing calculators are still showing last year’s number. Each page here shows the date the figure was last checked and the agency that publishes it. The law change log lists what moved and when.
How to read the results
Each calculator applies the general rule for the jurisdiction and lists the exceptions beneath the result. The statute governs, not the summary: when a result matters, open the citation and read the section. For anything contested, a local tenant union, housing agency or attorney can apply the rule to your facts. The methodology page explains what is and is not modelled.
