家庭主权债务分摊计算器
根据官方权威统计数据，测算不同家庭人口规模所对应的国家债务分摊额及年度利息成本。
Why Household Debt Share Matters
Sovereign debt is frequently reported in simplified per-capita averages. However, infants and non-earners do not pay taxes directly. Fiscal burdens, mortgages, and taxes are managed at the household level, meaning that family-level figures represent the true economic liability.
For a typical 4-person family, national debt shares quickly scale into significant sums. When factoring in the concentration among active taxpayers, the burden per contributing household multiplies more than twofold.
Methodological Framework & Mathematical Formulation
The WorldRealDebt simulator computes dual statistical perimeters: (1) Total Population Baseline — uniform division across registered citizens; (2) Active Taxpayer Perimeter — concentrated burden carried by productive earners paying personal and business income tax (approx. 39% of total population).
Formula 1 (Uniform): Household Share = (Total Sovereign Debt / Total Population) × Household Size
Formula 2 (Taxpayer): Active Taxpayer Share = (Total Sovereign Debt / Active Taxpayers) × Earning Members
Formula 3 (Interest Service): Annual Debt Service = (Annual Sovereign Interest Budget / Population) × Household Size
Sovereign interest payments are mandatory budgetary obligations. Rising interest outlays crowd out discretionary funding for infrastructure, healthcare, and education, inevitably leading to higher effective tax rates and economic drag across households.

- Q. 为什么除了人均口径外，还需要按家庭规模计算？
- 居民家庭的经济支出与纳税是以家庭为基本核算单元的。主权债务的本息偿还最终由纳税家庭的税收负担承担，按家庭人口规模测算更能反映普通居民家庭的实际经济承载压力。
- Q. “全体公民人均”与“实际纳税人口径”有何区别？
- 人均口径按全体总人口（含老少）简单均摊；实际纳税人口径则剔除无税收收入人群，以实际缴纳所得税的劳动力人口测算，更能反映主力纳税群体的真实负担。
- Q. 国债利息支出对个人家庭有什么影响？
- 国债利息属于政府刚性法定支出。利息支出占比过高会挤占民生、医疗、教育和科技研发等预算空间，并在中长期带来税负上升的压力。
- Q. 本计算器数据来自何处？
- 基于韩国企划财政部、美国财政部 Fiscal Data、日本财务省及各国家统计局的权威官方一手数据。
