| Section | Calculator Allowed? | Number of Questions | Time Allotted |
|---|---|---|---|
| Math No Calculator | ❌ No | 20 | 25 minutes |
| Math with Calculator | ✅ Yes | 38 | 55 minutes |
How to Choose the Best Calculator for the SAT
Not all approved calculators are equally effective for the SAT. Here’s how to pick the best one for your needs:
1. Graphing vs. Scientific Calculators
While both are allowed, graphing calculators (like the TI-84 Plus) offer significant advantages:
- Graphing functions: Essential for visualizing quadratic, exponential, and trigonometric functions.
- Programmability: Store formulas (e.g., quadratic formula, distance formula) to save time.
- Statistics features: Calculate mean, median, and standard deviation quickly.
- Matrix operations: Useful for systems of equations.
However, scientific calculators (like the TI-30XS) are lighter, cheaper, and sufficient if you’re comfortable with manual graphing.

3. Features to Prioritize
When selecting a calculator, prioritize these features for the SAT:
- Fraction calculations: The SAT loves fractions—your calculator should handle them seamlessly.
- Exponent and root functions: Essential for algebraic manipulation.
- Logarithmic functions: Needed for exponential growth/decay problems.
- Statistics mode: For mean, median, and standard deviation questions.
- Equation solver: Saves time on algebraic equations.
Common Mistakes to Avoid with SAT Calculators
Even with an approved calculator, students make critical errors. Avoid these pitfalls:
- Using a calculator on the No Calculator section: This is an automatic violation. Double-check the section before pulling out your calculator.
- Relying too much on the calculator: About 40% of the Math with Calculator section can be solved faster without one. Practice mental math and estimation.
- Forgetting to bring spare batteries: If your calculator dies during the test, you’re out of luck. Bring extras!
- Using prohibited features: Even if your calculator is approved, using banned functions (e.g., CAS mode on a TI-89) can invalidate your score.
- Not clearing memory: Some calculators store formulas or notes—proctors may reset your calculator if they suspect cheating.
- Bringing a loud calculator: Calculators that beep or make noise are prohibited and may disturb others.
Expert Strategies for Using Your Calculator on the SAT
A calculator is only as good as the person using it. Here’s how to maximize its effectiveness:
1. Know When Not to Use It
Use your calculator selectively. Skip it for:
- Simple arithmetic (e.g., 15% of 80)
- Basic algebraic manipulations
- Problems where estimation is faster
Example: For the problem “What is 30% of 50?”, calculating mentally (15) is faster than typing it into your calculator.
2. Pre-Program Common Formulas
Save time by programming these into your calculator before test day:
- Quadratic formula:
(-B ± √(B² - 4AC)) / (2A) - Distance formula:
√((x₂ - x₁)² + (y₂ - y₁)²) - Slope formula:
(y₂ - y₁) / (x₂ - x₁) - Compound interest:
A = P(1 + r/n)^(nt)
3. Master the Graphing Functions
Graphing calculators shine on these question types:
- Intersection points: Graph two equations and find where they intersect.
- Roots/zeros: Quickly find x-intercepts for quadratic or polynomial equations.
- Maxima/minima: Use the graph to identify vertex points on parabolas.
Pro Tip: Set your window appropriately. For most SAT problems, Xmin=-10, Xmax=10, Ymin=-10, Ymax=10 works well.
4. Use the Answer Choices
For multiple-choice questions, plug in the answer choices to verify:
- Write down the equation from the problem.
- Substitute each answer choice (A, B, C, D) into the equation.
- Use your calculator to check which one satisfies the equation.
Example: If the question asks for the solution to 2x + 5 = 11, plug in each choice to see which gives a true statement.
5. Practice with Your Calculator Before Test Day
Familiarity is key. Before the SAT:
- Complete at least 3 full Math with Calculator sections using your calculator.
- Memorize where key functions are (e.g., exponent, square root, fraction buttons).
- Practice switching between modes (e.g., degree vs. radian for trig problems).
What If You Don’t Have a Calculator?
While a calculator is helpful, it’s not required. Here’s how to succeed without one:
- Strengthen mental math: Practice arithmetic, percentages, and fractions daily.
- Learn estimation techniques: Round numbers to simplify calculations (e.g., 3.14 → 3 for π in some problems).
- Memorize key formulas: Quadratic formula, slope-intercept form, area/volume formulas.
- Use the answer choices: Plug in options to avoid complex calculations.
- Focus on the No Calculator section: Since you can’t use a calculator there, mastering these skills will help across both sections.
Note: If you can’t afford a calculator, some schools and libraries lend them out. The College Board also partners with organizations to provide calculators to low-income students.
