Round to the Nearest Dollar
Rounding to the nearest dollar drops the cents entirely: $47.50 becomes $48, while $47.49 becomes $47. The IRS requires whole-dollar rounding on many US tax forms (amounts under 50 cents drop, 50 cents and over rise), and budgets, quotes and salary figures are routinely quoted this way because cents rarely change a decision. All values on this page use standard half-up rounding.

How to use the Round to the Nearest Dollar
- Check Number to round: 47.5.
- Check Round to: nearest.
- Check Nearest multiple of: 1.
- Review the Round to the Nearest Dollar result and its exact-value comparison table.
- Verify assumptions before applying the result.
Formula
Round half up at the chosen precision: decimal places count digits after the point, significant figures count digits that carry meaning from the first nonzero digit, and nearest-multiple rounding snaps to a grid such as the nearest 100.

Frequently asked questions
Rounding to the nearest dollar drops the cents entirely: $47.50 becomes $48, while $47.49 becomes $47. The reference table on this page shows 8 worked examples computed with exactly that rule.
Exactly fifty cents is the tie: $47.50 rounds up to $48 under the half-up rule, matching the IRS whole-dollar convention.
Use it for tax-form entries, budgets, estimates and any figure that will be read aloud — nobody says 'forty-seven dollars and fifty cents' in a planning meeting.
1299.4 rounds to 1299. You can verify it in the table on this page, or type any other value into the calculator above.
The Form 1040 instructions allow (and effectively expect) whole-dollar entries: amounts under 50 cents drop to the lower dollar, amounts of 50 cents and over rise to the next dollar — the same half-up rule as this page. If you round one entry you must round consistently across the return, and the IRS's own computers apply the same convention when checking the maths.
No. Banker's rounding (round-half-to-even) is used in some scientific and financial standards to reduce bias over huge datasets, but this page — and the parent rounding calculator — always rounds a halfway value up, which is the convention taught in schools and used for tax forms.
Yes, with one nuance: the engine rounds halves toward positive infinity, so 47.5 rounds up to 48 at the nearest dollar while -47.5 becomes -47. Away from exact halves, negative values round to the nearest candidate just like positive ones.
