– why is fiscal deficit mentioned as a % of GDP (gross domestic product) ?

Question

I was recently reading news on India’s interim budget and I read something that by 2025 they (the country) expect fiscal deficit to be x% of GDP, and it had me confused.
How is GDP, which a metric for production and exports imports within a country, an appropriate base for fiscal deficit?

Kinda like a debt to income ratio. If your debt is 80% of your income level it’s gonna be hard to fathom you can pay back any new debt.
