Low flow toilets use 1.6 gallons per flush.
The new(2014) ones are 1.28
If the toilet works each time on one flush, they use roughly half the water of a standard toilet. You would then use half as much a month on the toilet. They do not always flush completely on the first flush and the toilet is only a part of the water bill.
3 liters
In a modern toilet you use 13 litres per flush.
It takes 1 bucket of water when we flush.
You use anywhere from 1 cup of water to 5 cups of water to flush the toilet. This is per time you flush the toilet.

There is about four to five gallons wasted if you flush a toilet but I don't believe that it makes a difference if the handle is loose or not. Unless, the toilet is leaking from the handle or somewhere else.
5 gallons
The term "GPF" stands for Gallons Per Flush and it indicates how much water a toilet uses with each flush. The lower the GPF, the less water is used, which can help conserve water and reduce water usage in households.
