Use the result with context

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

Subtract the previous period GDP from the current value, then divide by the previous value. GDP moving from 1,000 to 1,050 represents 5% growth.

GDP growth (%) = (current GDP − previous GDP) ÷ previous GDP × 100

Worked example

Enter these known values and leave the other values blank.

GDP in the current period
1050 USD · million
GDP in the previous period
1000 USD · million
GDP growth
5 %

Assumptions and limitations

  • Use values from a consistent period, scope and currency. The stated formula defines this simplified model; the explanation describes quantities it leaves out.

Common questions

Should I use nominal or real GDP?

Use real GDP for growth adjusted for price changes. Whichever series you choose, keep currency, scale, seasonal adjustment and period definitions consistent.
