Compare your current base rent and mandatory fees with a new renewal offer. See the dollar increase, percentage increase and total impact over the months you expect to stay.

Compare like with like.

Enter base rent separately from mandatory monthly fees. Put one-time renewal charges and credits in their own fields so the monthly increase is not distorted.

No sample rent or fee amounts are preloaded. Use the current lease and written renewal offer.

Enter current and new base rent.

Both rent amounts are required before the calculator can show a meaningful percentage or cost change.

Compare the actual offer

Base rent and all-in rent are different comparisons

A renewal can raise base rent, add a new mandatory service fee, change an existing monthly fee or include a one-time renewal charge. Comparing base rent alone can miss the real change in recurring housing cost.

Use two percentage changes

Base-rent percentage change: compares only the stated rent amount.
All-in monthly percentage change: compares base rent plus the mandatory monthly fees you entered.

Keep one-time items separate

A one-time renewal fee or credit changes the cost over the selected term but does not change the recurring monthly amount. The calculator therefore shows both the monthly difference and the modeled period difference.

Documents worth saving

Current lease and current monthly fee schedule.
Written renewal offer with term, rent and response deadline.
New mandatory fee disclosure or resident-benefit/service package.
Any renewal credit, concession or one-time administration charge.
Month-to-month quote if that is an alternative.
Property-state or local notice/rent rules when applicable.

Cost calculator only. This tool does not decide whether a rent increase, fee increase or renewal term is lawful. Rent-control, notice and other rules can be state- or locality-specific.
