Income minus expenses, divided by income. The Bureau of Economic Analysis publishes a national version of the same calculation each month, which is where the widely quoted US household figure comes from.
Promi labels the result in three bands, matching what the app shows: below 10% is thin, 10 to 20% is solid, and 20% or more is strong. The commonly cited benchmark is 20% and above. A negative rate means the month was funded from reserves or credit.
The reason this number gets more attention than income is that it sets two things at once. It determines how fast savings accumulate, and it determines how much those savings have to cover later, since a lower spending level is also a smaller number to replace in retirement.
