SAT Math Formula Chart
The SAT gives you some formulas, but not every formula worth knowing. This chart separates what appears on the reference sheet from what you should memorize.

High-value formulas
Prioritize formulas that save time or appear inside multi-step problems.
| Topic | Formula | Use |
|---|---|---|
| Slope | (y2 - y1) / (x2 - x1) | Lines and rates |
| Quadratic formula | x = (-b +/- sqrt(b^2 - 4ac)) / 2a | Non-factorable quadratics |
| Circle area | A = pi r^2 | Geometry |
| Triangle area | A = 1/2 bh | Geometry |
| Exponential growth | y = a(1 + r)^x | Growth models |
What to memorize
Memorize formulas that let you move faster than opening the reference sheet.
- Slope-intercept form
- Point-slope form
- Vertex form
- Distance formula
- Percent change
How to use this on 1600.now
Read the chart once, then switch into practice. The site is built around filtered bank questions, timed modules, score tools, and saved practice sets, so the next step should be an action inside one of those tools.
- Use the question bank when the page names a skill or domain.
- Use timed modules when the page is about pacing or test format.
- Use score tools when the page is about score targets or admissions decisions.
How to turn this into SAT Math points
For Math resources, the useful question is always: which setup gets me to the answer fastest? Decide between mental math, paper algebra, Desmos, or answer-choice testing before you start calculating.
- Use Desmos for intersections, roots, vertices, tables, and regression.
- Use paper algebra when the equation is short or already factored.
- Use answer choices when they are ordered and easy to substitute.
- After every miss, label it as setup, algebra, calculator, or reading error.

FAQs
Does the Digital SAT provide a formula sheet?
Yes. The Math section includes a reference sheet, but you should still memorize common algebra and function forms.
What formula matters most for SAT Math?
Slope is the highest-frequency formula because it appears in lines, functions, tables, graphs, and word problems.
