Non-reversible (per port)| Port | Allowed | Used | Balance | Result |
|---|---|---|---|---|
| Load | 5d 0h | 6d 0h | -1d 0h | −$18,000 |
| Discharge | 4d 4h | 3d 12h | 0d 16h | +$6,000 |

Allowed laytime is cargo ÷ agreed rate; despatch is paid at half the demurrage rate on time saved. Non-reversible settles each port separately (demurrage at one port is not reduced by time saved at the other); reversible nets the combined allowed against the combined used. This is a working estimate — the governing charter party and statement of facts control.
