How to use the percent yield calculator
Compare actual and theoretical yield. Enter actual yield, theoretical yield in the fields above; the percent yield is computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- a — Actual yield (g)
- t — Theoretical yield (g)
Worked example
With actual yield = 8.2 g, theoretical yield = 10 g, the calculator gives percent yield ≈ 82 %.
Frequently asked questions
What is the formula for the percent yield calculation?
Percent yield (%) = 100 × a / t. Here a is actual yield (g), t is theoretical yield (g).
What inputs do I need for the percent yield calculator?
You need actual yield in g, theoretical yield in g. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
