Best SAT Reference Sheet & Formula Cheat Sheet: 35+ Formulas You MUST Memorize

Looking for a complete SAT formula sheet to ace the math section? You're in the right place.

Here's what most students don't realize: the official SAT math reference sheet only gives you 12 geometry formulas. But to score well, you need 35+ more formulas memorized.

The SAT reference sheet covers basic geometry—circles, triangles, and volumes. But roughly 85% of SAT math questions fall under Algebra, Advanced Math, and Problem-Solving & Data Analysis, where zero formulas are provided.

This SAT math formula sheet and cheat sheet covers every must-memorize formula organized by SAT's four content categories, with free interactive flashcards you can study right now.

What's on the Official SAT Math Reference Sheet?

Before diving into our SAT formula cheat sheet, let's look at what the official SAT reference sheet actually provides:

The 12 formulas given:

• Circle: $A = \pi r^2$, $C = 2\pi r$
• Rectangle: $A = \ell w$
• Triangle: $A = \frac{1}{2}bh$
• Pythagorean theorem: $c^2 = a^2 + b^2$
• Special right triangles (30-60-90 and 45-45-90 ratios)
• Volume: rectangular prism, cylinder, sphere, cone, pyramid

Plus 3 facts:

• Circle = 360° = 2π radians
• Triangle angles sum to 180°

That's it. Everything below is NOT provided on the official SAT formula sheet—you must have it memorized. That's why you need this comprehensive SAT math cheat sheet.

SAT Math Formula Sheet: Content Breakdown

Category	Weight	Formulas Provided
Algebra	~35% (13-15 questions)	None
Advanced Math	~35% (13-15 questions)	None
Problem-Solving & Data Analysis	~15% (5-7 questions)	None
Geometry & Trigonometry	~15% (5-7 questions)	12 formulas

Notice the problem? 70% of SAT math has zero formula support. That's why this SAT math formula cheat sheet is essential. Let's fix that gap.
