DoD Travel Compensatory Time Calculator

Support this tool
⚠ Notice — This is not an official DoD website and does not claim to be. It was built by a private DoD civilian developer who got tired of calculating his own travel comp time by hand. This tool is for DoD civilian employees only. Sorry military personnel, contractors, and NAF employees — this won't work for you. Travel comp time does not apply to PCS moves — only TDY travel.
⛔ Accuracy Disclaimer — This tool gives you an estimate only. The results depend on what you enter, so always double-check with your supervisor, timekeeper, and HR office before submitting a comp time claim. Verify your results against all applicable regulations. Use at your own risk. The creator assumes no liability for any errors, omissions, financial consequences, or adverse employment actions resulting from use of this tool. By using it, you accept full responsibility for verifying results before taking any official action.
