Currently the HIVE inflation is around 9.5%. 15% of that is going to the HP holders or around 1.43% interest. This number is dynamic and compounding so its bigger than 1.43% and some estimated it around 2% on a yearly basis.
I recently did a “deep dive” into this:

As of a few weeks ago, I came up with a “snapshot” of 2.73%
Just read it :) You have done a great job!
Far more accurate that what I have stated above :)
Calculating the exact inflation in % value is tricky because it basically depends on the virtual supply, that depends on the HIVE price. Then we have to see how much of the overall token is powered up.
Anyway the main point ....2.73% is acctualy a great ROI, and its beeing hiden away from users. Imagen you have a daily transaction that says .... here is XX HIVE as a reward for staking
