Notifying a tenant of a rent increase in writing — with a clear effective date and the exact new amount — is standard practice for landlords, and calculating the increase amount and percentage automatically avoids simple math errors in an important notice.
This generator creates a rent increase letter with the increase amount and percentage calculated for you.
How it works
Enter the landlord and tenant details, the current and new rent, and the effective date. The generator calculates the dollar increase and percentage automatically and produces a formal notice letter, ready to download as a PDF.

Examples
$1,500 to $1,650
Increasing rent from $1,500 to $1,650 per month is a $150 increase, or 10% — both figures are calculated automatically and included in the letter.
Who should use it
- Notifying a tenant of an upcoming rent increase at lease renewal.
- Documenting a rent increase in writing for record-keeping purposes.
Industry applications
- Residential property management
- Landlord and tenant relations
Advantages
- Calculates the dollar increase and percentage automatically.
- Produces a clear, professional notice letter ready to send.
Limitations
- Doesn't know your specific local notice-period or rent-control requirements — you must verify those yourself.
Common mistakes to avoid
- Sending a rent increase notice without checking local notice-period requirements, which can invalidate the increase.
- Attempting to raise rent mid-term on a fixed-term lease without a lease provision allowing it.
Best practices
- Check your local and state landlord-tenant law for required notice periods and any rent-increase caps before sending — these vary widely and some cities have strict rent control rules.
Tips
- Sending rent increase notices well before the required minimum notice period (rather than exactly at the deadline) gives tenants more time to plan and reduces the chance of disputes over timing.
