Choosing the right calculator isn’t always easy, so it helps to know what you need from the device. Here are some things to consider:

  • Purpose: One of the easiest ways to find a suitable calculator is to consider why you need it. For instance, if you have an exam or coursework to study, then you will likely need a scientific or graphing calculator. Those that need one for doing arithmetic should be fine with a more basic handheld calculator, while anyone that needs a calculator for their business may benefit from financial calculators that print off documents.
  • Budget: Advanced calculators that offer a range of functions tend to cost a lot more than a basic pocket calculator, so it may help to set yourself a budget. Graphing calculators in particular are rather expensive but may be necessary, so it’s often a good idea to shop around for the best deal possible. Consider buying second hand if you are on a tight budget.
  • Power Source: Many great calculators don’t come with batteries, rather using solar power to operate. While this is environmentally friendly and much cheaper, it can be unreliable in some cases. This isn’t much of a problem for most users, but anyone buying a calculator for an exam should consider a device with a backup battery to ensure it doesn’t die when they need it most!
