Round any dollar amount to the nearest whole dollar instantly
• Look at the cents (decimal part)
• If 50¢ or more, round up to next dollar
• If less than 50¢, round down
• Result has no decimal places
• $19.50 → $20 (50¢ ≥ 50¢, round up)
• $5.49 → $5 (49¢ < 50¢, round down)
• $12.99 → $13 (99¢ ≥ 50¢, round up)
• $100.00 → $100 (already whole)

When creating rough budgets or financial plans, rounding to whole dollars makes calculations easier and the budget more readable.
Example: Monthly bills of $125.43, $89.12, and $45.87 → $125 + $89 + $46 = $260
In some countries or situations, cash transactions are rounded to the nearest dollar for convenience.
Example: Total of $19.75 → Round to $20 and pay with a $20 bill
Large financial statements often round amounts to thousands or millions of dollars for clarity.
Example: Revenue of $1,234,567.89 → Report as $1,235,000 (rounded to nearest thousand)
For fast estimates while shopping or calculating, rounding to whole dollars simplifies arithmetic.
Example: Items at $12.99, $7.49, and $5.50 → $13 + $7 + $6 = $26 (approximate total)
Look at the cents (the decimal part of the amount). If the cents are 50 or more, round up to the next dollar. If the cents are less than 50, round down to the current dollar. For example, $19.50 rounds to $20, and $19.49 rounds to $19.
$19.50 rounds to $20. Since the cents amount (50) is exactly 50, we follow the standard rule to round up to the next whole dollar.
Rounding to the nearest dollar simplifies financial calculations, makes budgets easier to read, and is useful for estimates. It's also necessary in some cash-only transactions where exact change isn't available or practical.
Most stores don't round displayed prices or final totals. However, some countries (like Canada) have eliminated pennies and round cash transactions to the nearest 5 cents. Electronic payments use exact amounts.
Calculate taxes first with full precision, then round the final total if needed. For example: $19.99 item + 8% tax = $21.59. If rounding to nearest dollar, this becomes $22.
For accuracy, add all amounts first with full precision, then round the final sum. Rounding each number first, then adding can create small errors that accumulate.
