Calculate rent increase by percent or amount — see new rent, increase and yearly impact.
Enter values above and click Calculate — results will appear here with the formula explained.
New rent is either current rent times (1 plus percent increase) or current rent plus a fixed dollar amount, depending on which field you fill; the yearly impact simply multiplies the monthly increase by twelve. At $1,800 with a 5% adjustment, rent becomes $1,890, an extra $90 per month and $1,080 per year — the number that matters for lease-renewal negotiation.
Every jurisdiction writes its own cap. Many rent-controlled markets limit annual increases to 3–10% or to CPI, sometimes with additional tenant protections that allow only one increase per twelve months. This tool computes the arithmetic only; verify the legal ceiling with primary sources before signing or issuing notice.
