General calculator policy

Acceptable calculators are allowed for mathematics questions only. You will not be allowed to share calculators. You will be dismissed and your scores canceled if you use your calculator to share information during the test, or to remove test questions or answers from the test room.

Use of calculators during the SAT

Every question in the mathematics portion of the SAT can be solved without a calculator. However, we suggest that you bring and use a calculator, especially one with which you are familiar. We recommend the use of a scientific or graphing calculator. You may not use a calculator while working on the critical reading or writing portions, and must put the calculator away during these portions of the test.

Use of calculators during SAT Subject Tests

Some questions on the Mathematics Level 1 and Level 2 Subject Tests cannot be solved without a scientific or graphing calculator. We recommend the use of a graphing calculator rather than a scientific calculator. Calculators may only be used on the Mathematics Subject Tests. You may not use a calculator for other SAT Subject Tests and must put it away when not taking a mathematics test.

Calculator tips

  • Bring a calculator with you, even if you're not sure if you will use it. Calculators will not be available at the test center.
  • If you don't use a calculator regularly, practice using it on sample SAT mathematics questions before the test. Use a calculator with which you are familiar.
  • All questions on the SAT can be answered without a calculator. The questions do not require complicated or tedious calculations.
  • Don't buy an expensive, sophisticated calculator just to take the test. Although you can use them for the test, more sophisticated calculators are not required for any problem on the test.
  • Don't try to use a calculator on every question. First, decide how to solve the problem, and then decide whether to use the calculator. The calculator is meant to aid you in problem solving select questions, not to get in the way.
  • It may help to do scratch work in the test book. Get your thoughts down before using your calculator.
  • Make sure your calculator is in good working order and that batteries are fresh. If your calculator fails during testing and you have no backup, you'll have to complete the test without it.

Acceptable calculators

If you have a calculator with characters that are one inch or higher, or if your calculator has a raised display that might be visible to other test-takers, you will be seated at the discretion of the test supervisor. 

Only battery-operated, handheld equipment can be used for testing. No power cords are allowed. Calculators permitted during testing include:

  • Most graphing calculators (see chart)
  • All scientific calculators
  • All four-function calculators (not recommended)
