Writing & StyleStyle guide

Dollar Formatting

Dollar amounts can be written with a dollar sign, a currency code, or the word “dollar,” depending on context and the need to disambiguate currencies. Microsoft style allows the symbol when the intended currency is clear and otherwise uses the code before the amount.

Quick answer

Use “$” when the intended dollar currency is clear; use an explicit currency code such as USD when ambiguity matters. Follow the governing locale and house style for spacing and decimals.

Important caveats

Ambiguity Boundary

The dollar sign is used by multiple currencies, so an explicit code can be clearer in international or multi-currency material.

Style Boundary

Decimal precision, separators, and spacing can vary by locale and publication; this guide does not impose one universal money format.
