Public Debt & Debt-to-GDP

The total amount the central government owes, measured against the size of the economy to judge whether that debt load is sustainable.

Explain it like I'm 10

A person earning ₹10 lakh a year with a ₹5 lakh loan is in a very different position from a person earning ₹1 lakh a year with the same ₹5 lakh loan — the debt is identical, but the ability to service it isn't. Debt-to-GDP does exactly this for a country: it takes the government's total outstanding borrowing and expresses it as a share of the whole economy's annual output, because a bigger, faster-growing economy can comfortably carry a debt load that would sink a smaller, stagnant one.

The formula

Debt-to-GDP Ratio (%) =
    Total Outstanding Central Government Debt
    ────────────────────────────────────────── × 100
                Nominal GDP

Trajectory:
  FY21 (pandemic peak)  ≈ 61.4% of GDP
  FY26 (RE)             ≈ 55.6–56.1% of GDP
  FY31 (target)         = 50% ± 1 percentage point

Historical data

Central government debt, % of GDP

The post-pandemic decline reflects both active fiscal consolidation and strong nominal GDP growth doing some of the work — a growing denominator lowers the ratio even without a single rupee of debt being repaid.

Who calculates it

The Ministry of Finance's Budget Division and the Controller General of Accounts (CGA) track central government debt; the RBI separately monitors combined centre-plus-state general government debt as part of its financial stability assessments.

Where this number can mislead you

⚠The commonly quoted figure is centre-only — India's combined (centre + state) general government debt-to-GDP ratio runs meaningfully higher than the headline central number.
⚠The ratio is sensitive to the GDP denominator: a base-year GDP revision, like the 2011-12-to-2022-23 shift, can move the ratio without any change in the actual debt stock.
⚠A falling ratio can result mostly from strong nominal GDP growth (including inflation inflating the denominator) rather than genuine reduction in the debt burden itself.
⚠Off-budget borrowings and contingent liabilities of government-owned entities and guarantees aren't always fully captured in the headline central government debt figure.

Reality check

The government's central debt-to-GDP ratio is projected to ease to roughly 55.6-56.1% by FY26 (Revised Estimate), down from a pandemic-era peak of 61.4% in FY21 — and the government has now formally shifted its primary fiscal anchor from the annual fiscal deficit percentage to this debt-to-GDP ratio itself, targeting a further glide down to 50% (±1 percentage point) by FY2030-31.
