What Is the Digital SAT Formula Sheet?
The digital SAT formula sheet is a built-in reference available directly within the Bluebook testing platform during the Math sections. Unlike the old paper SAT, where a reference sheet was printed at the start of the Math booklet, the digital version is accessible at any point during the exam through a button in the test interface.
It is compact by design. College Board includes only the formulas they consider essential for the geometry and measurement questions on the test. Algebra, which makes up the largest portion of SAT Math, is not covered by the sheet at all.
Why Is the Digital SAT Formula Sheet Important?
- Convenience – The digital format means the formula sheet is always accessible during the test. There’s no need to memorize every single formula.
- Saves Time – Instead of trying to recall complex formulas under pressure, you can use the formula sheet as a reference to quickly solve problems.
- Boosts Confidence – Knowing that the formulas you need are right at your fingertips can help you feel more confident and focus on the problem-solving process rather than stressing over remembering the formulas.
What’s Included in the Digital SAT Formula Sheet?
The digital SAT formula sheet includes the most important formulas you’ll need for the test, including:
- Algebra – Formulas for solving linear equations, quadratic equations, and systems of equations.
- Geometry – Key formulas for areas and volumes of shapes such as circles, triangles, and rectangles. This also includes rectangular prisms, cylinders, spheres, and cones.
It’s important to note that the formula sheet in the digital format is relatively compact, so it includes only the formulas deemed necessary for solving the problems on the SAT.
While the formula sheet includes key formulas, many concepts still require understanding and application rather than direct substitution.
The below formula sheet is the official version from CollegeBoard: 
What Is NOT on the Formula Sheet
This is the section most students miss. The formula sheet covers geometry and measurement only. Everything below must be memorized because it will not be provided.
You must memorise these
- Slope formula: (y₂ – y₁) / (x₂ – x₁)
- Slope-intercept form: y = mx + b
- Quadratic formula: x = (-b ± √(b² – 4ac)) / 2a
- Standard form of a quadratic: ax² + bx + c = 0
- Vertex form of a quadratic: y = a(x – h)² + k
- Standard form of a circle: (x – h)² + (y – k)² = r²
- Distance formula: d = √((x₂ – x₁)² + (y₂ – y₁)²)
- Midpoint formula: ((x₁ + x₂)/2, (y₁ + y₂)/2)
- Exponential growth/decay: y = a(1 + r)ᵗ
- Average: Sum of values / number of values
- Probability: Favorable outcomes / total outcomes
- Trigonometric ratios: SOH-CAH-TOA
How to Use the Digital SAT Formula Sheet Effectively
While it’s easy to think of the digital formula sheet as a crutch, you should still aim to be familiar with the formulas beforehand to save time. Here’s how to use it to your advantage:
1. Familiarize Yourself Before the Test
Although the formula sheet is available during the test, it’s a good idea to review the formulas ahead of time. This will help you become more comfortable with the concepts and better understand when to use each formula.
2. Practice with the Digital Interface
If possible, try out digital SAT practice tests to get used to how the digital formula sheet works within the test interface. The more you practice, the easier it will be to navigate the sheet during the actual exam.
3. Use It as a Quick Reference
During the test, feel free to use the formula sheet whenever you’re unsure of a formula or need a quick refresher. However, don’t spend too much time looking at it. Your goal should be to solve the problems efficiently, using the formula sheet only when necessary.
4. Don’t Rely on It Too Much
The digital SAT formula sheet is a helpful tool, but it’s still important to know the formulas and concepts. Try to solve problems without constantly relying on the formula sheet to improve your speed and problem-solving skills.
Key Tips for Success on the Digital SAT
- Understand the Concepts – Don’t just memorize formulas. Understand how and when to apply them. This deeper understanding will help you solve problems more efficiently.
- Practice, Practice, Practice – Use official practice tests and sample problems to familiarize yourself with the digital SAT format, including the formula sheet.
- Stay Calm and Focused – The digital SAT format may feel a little different, but remember that it’s still just a test. Stay calm, take your time, and use the formula sheet to help you when necessary.
