Calculator

Estimated 1RM calculator

Enter a set you finished. The Epley formula turns that into a rough single-rep equivalent. Do not load that number because the calculator produced it.
Units

Use the reps you finished with control.

The estimate uses the Epley formula: weight × (1 + reps ÷ 30). It is not a load to test. Read progressive overload without ego lifting before you add weight.
