What it means...

To cost an extremely large amount of money — more than one can comfortably afford.

When something breaks the bank, it is so expensive that it stretches or exceeds your financial limits.

It is also commonly used in the negative — something that does not break the bank is reasonably priced.

Use it when…

  • When a purchase or expense is far too expensive relative to your budget
  • When reassuring someone that a gift or outing will not cost too much
  • When describing a major financial splurge that significantly depletes your savings

Don’t confuse with...
