Another common saying is "tightarse"


All these terms have similar, but slightly different meanings.

For example, a scrooge often does not live in poverty, but a miser would. A cheapskate might buy something cheap, a tightarse might not buy it at all. A penny pincher might take money, but not be liberal with spending it.


Some similar English sayings include:
"If you look after your cents the dollars will take care of themselves"
"If you look after the pennies, the dollars will look after themselves."

These sayings are not exactly the same as the "miser" way of life. A miser looks after his pennies, but may not necessarily have financial smarts. A person who takes care of their pennies may not necessarily be a miser. The penny/pound or dollar/cents sayings imply financial smarts. Miser implies a more miserable person who won't let go of their money.

Wikipedia compares a miser with a capatilist. "The difference is that, unlike the miser, the capitalist does spend his money and is typically portrayed leading a decadent life."
