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

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.
