Formula
output gap=100(actual−potential)/potential.
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Potential GDP is a supplied estimate. This arithmetic does not estimate productive capacity.
Example Calculation
Example inputs
- Actual real GDP: 950
- Potential real GDP: 1000
Actual real GDP = 950; Potential real GDP = 1000. The primary result is -5.
Frequently asked questions
How do I use this calculator?
Enter actual real gdp, potential real gdp. The result updates automatically. Use Reset to restore the example values.
What method does it use?
output gap=100(actual−potential)/potential.. Potential GDP is a supplied estimate. This arithmetic does not estimate productive capacity.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
