World of Warships — Battle Experience Calculation

n World of Warships, the after battle experience calculation relies on a number of bonus multipliers. The bonus multipliers are directly linked with your battle performance.

List of Bonus Multipliers

1. Premium Account: Xprem == 0,5 for 50% bonus
2. Bonus First Win of the Day: Xfirstwin == 0,5 by default. Also, can become 1 for x2 Win Bonus or 2 for x3 Win Bonus.
3. Missions: Xmission == value modified by mission. Example: 200% value or a x3 value mission related to a 1multiplier.
4. Camouflage: Xcamo == 0,5 for Permanent Premium Camouflage or 1 for Special Event Camouflage.
5. Signal Flags: Xsignalflag == value applicable n times. Where n is the number of signal flags hoisted on a given ship.
6. Memorable Flags: Xmemflags.

Experience Formula

The following formula applies to calculate the Experience.

1. XPbase == XPbattle * (1 + Xprem)
   • The Premium Account bonus applies first to XPbase and the result is rounded to get a new XPbase value.
2. XPship == XPbase + XPbase * Xfirstwin + XPbase * Xmission + XPbase * Xcamo + XPbase * Xsignalflag + XPbase * Xmemflags
3. Simplifying…
4. XPship == XPbase * (1 + Xfirstwin + Xmission + Xcamo + Xsignalflag + Xmemflags)

Formula Demonstration

To demonstrate how this formula works, Captain Holzbein_Jack will go on a battle to earn fame and honour, and also earn some experience for his beloved vessel: The HMS Warspite.

Considering

1. There’s an active Premium Account.
2. The HMS Warspite is a Premium ship, which also has a special Premium Camouflage.
3. The following two (2) signal flags are hoisted: Equal Speed Charlie London and Zulu Hotel.
4. There’s also hoisted once (1) memorable flag.
5. This is the first battle with this ship today.
6. The battle occurred during Saint Patrick’s day, so there’s a multiplier bonus of x3. Let’s hope he wins!

Let’s see how this worked out, shall we.

After an heroic battle against formidable odds, the results were the following:

Let’s verify with the formula the results

XPbase == 1.295 * (1 + 0,5 (Premium) ) = 1.295 * 1,5 = 1.942,5 ~ 1.943

XPship == 1.943 * (1 + 2 (because x3 for event) + 0 (no mission that improved the exp gain) + 1 (for the special camo on the ship) + 0,5 (Equal Speed Charlie London) + 0,05 (for the memorable flag)) = 1.943 * 4,55 = 8.840,65 ~ 8.841

XPship == 8.841
