Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What formula does the rent increase calculator use?
It uses monthly increase = current rent x (increase percent / 100), new monthly rent = current rent + monthly increase, and new annual rent = new monthly rent x 12. For example, 1500 rent at 3% gives a 45.00 increase, 1545.00 new monthly rent, and 18540.00 new annual rent.
Which inputs are accepted?
Enter a current monthly rent greater than zero through 1000000000 and an increase percentage from 0% to 100%. Displayed amounts are rounded to two decimal places.
Does this include fees, utilities, or lease terms?
No. It estimates base rent only from the two inputs. Deposits, fees, utilities, concessions, and local rent-control rules are not included, so check your lease and treat the result as a planning starting point.
Do my values stay private, and is this financial advice?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter. This is a general planning estimate, not financial advice.
