Frequently asked questions
Is real GDP growth this simple?
This is the headline arithmetic. Real economics separates real from nominal growth (stripping out inflation) and compounds over many years, but the single-period maths is exactly this.
Can I model a recession?
Yes, enter a negative growth rate to see GDP contract. A couple of negative quarters in a row is the rough definition of a recession.
Why express growth as a percentage at all?
Because it lets you compare economies of wildly different sizes. A 6% growth rate means the same proportional progress whether the economy is tiny or enormous.
What units should I use?
Any consistent unit, usually billions. The calculator does not care about the unit; it just scales the number you give it.
