Enter an amount and select currency, then click Make Change.

The change maker calculator breaks down a monetary amount into the minimum number of bills and coins using a greedy algorithm. This is useful for cashiers, cash management, and teaching money concepts. The algorithm iteratively subtracts the largest denomination that fits in the remaining amount, ensuring the fewest pieces possible. The calculator supports multiple currencies: USD (dollars and cents), EUR (euros and cents), GBP (pounds and pence), and RUB (rubles and kopecks). It handles both whole amounts and decimal amounts with cents/pence/kopecks. The result shows each denomination used, the count, and subtotal, plus the total number of items. This tool is ideal for retail, banking, and educational purposes.

1. Enter the Amount in the input field (e.g., 123.45).
2. Select the Currency (USD, EUR, GBP, or RUB).
3. Click Make Change to break down the amount.
4. The result shows bills and coins used, with counts and subtotals.
5. The total number of items and any remaining amount are displayed.
6. Click Reset to restore default example values.
