National Health Expenditure Per Capita Calculator
Calculate the national health expenditure per capita by dividing total national health expenditure by the total population. Compare results against global and regional benchmarks.
Total National Health Expenditure (USD)
Enter the total health spending in US dollars (e.g., 4.5 trillion = 4500000000000)
Total Population
Enter the total national population
National GDP (USD, optional)
Optional: Enter GDP to calculate health expenditure as % of GDP
Exchange Rate to USD (optional)
Optional: Conversion rate if expenditure is in local currency (1 = already in USD)
Calculate
function natCalc() { const resultDiv = document.getElementById('nat-result');
// Parse inputs const rawExpenditure = parseFloat(document.getElementById('nat-total-expenditure').value); const population = parseFloat(document.getElementById('nat-population').value); const gdp = parseFloat(document.getElementById('nat-gdp').value); const exchangeRate = parseFloat(document.getElementById('nat-currency-rate').value);
// --- Validation --- const errors = [];
if (isNaN(rawExpenditure) || document.getElementById('nat-total-expenditure').value.trim() === '') { errors.push('Total National Health Expenditure is required.'); } else if (rawExpenditure 0) { resultDiv.style.display = 'block'; resultDiv.innerHTML = 'Please fix the following errors:' + errors.map(e => '').join('') + ''; return; }
// --- Core Formula --- // Step 1: Convert expenditure to USD const expenditureUSD = rawExpenditure * rateVal;
// Step 2: NHE Per Capita = Total Health Expenditure (USD) / Population const nhePerCapita = expenditureUSD / population;

#### Formula
NHE Per Capita (USD) = Total National Health Expenditure (USD) ÷ Total Population
Where:
- Total National Health Expenditure (USD) = Raw expenditure × Exchange rate to USD
- Health Expenditure as % of GDP = (Total Health Expenditure ÷ GDP) × 100
- GDP Per Capita = GDP (USD) ÷ Population
Example (USA 2022): $4.5 trillion ÷ 331 million = ~$13,493 per capita
