Inflation adjustment letter (United States)

To request or announce an adjustment to rent, an installment, a fee or a salary using the official index.

A letter ready to hand over, filled in with your updated amount, plus the backing for the math: the official index for each date, the agency that publishes it and the link to the source.

With the backing in plain sight, the other side can check the number in a minute and the conversation becomes about the index, not the math.
