Overview
A detailed breakdown of base xp, credits, and mechanics involved for earning both.
Prelude
Greetings. There is much confusion about the disparity for earning base xp and credits. I would like to go over some of this to help newer players understand, as well as helping veterans that may have not known some of this. This information is credited to Wargaming and was pulled from multiple sources they provide.
Service Costs

Service Costs
“I was earning credits fine before, but now I am not earning nearly as much.”
* or *
“Why am I losing credits after each battle?”
The service cost of your ship is more than just the ship itself, or it’s type. The size of your ship is not a factor – only it’s tier. After that, you have deductions to your credits for premium consumables if you are using any. Keep in mind, upgraded consumables will no longer be considered “premium” when patch 0.9.4 is released.
View the image below for a table to calculate service costs. Note, the highlighted tier (7) is the last tier before things become much more expensive.

Credit Earnings – Explained
——————————————————————————————————————————-
After a battle, each player receives base credits according to his/her contribution to the battle.
The keyword here, is “contribution” – to the team.
The greatest base earnings come from damage done to enemy ships. The rewards for damage is determined by the percentage of the target ship’s hit points removed, NOT the amount of raw damage done.
Meaning: Removing 90% of a destroyer’s HP will generate the same base earnings as removing 90% of a battleship’s HP at the same tier.
The rewards from damage scale depending on the tier disparity between ships.
More is earned for damaging a higher tiered than a lower tiered ship.
So, don’t be upset about the uptier, be thankful for the opportunity to earn more!
Damage to ships and aircraft, kills, and captures make up about 85% of total earnings.

Note: The highlighted areas mark a difference for base XP vs credits, as you will see on the next topic – “Base XP”

Base XP – Explained
—————————————————————————————————————————–
The amounts of base xp earnings appear in the post-battle report.
Base XP earned appears on the ‘Team Score’ tab and is used to rank team performance. It also appears on the ‘Credits and XP’ tab in the left-hand (non-premium) column as XP/Received/Earned above where its use in calculating derived XP values is broken out.
After a battle, each player receives base experience according to his/her contribution to the battle. You see that word again – “contribution”. This is a team effort, and when you play as a team, you are far more likely to earn more base xp.
View the image below for a more detailed understanding. You will see the same highlighted areas here as the one before, because they differ between the two earning types.

Tanking, Spotting, and Other Factors
——————————————————————————————————————————-
The following typically contributes less than 15% of the total earned credits and base xp.
Potential Damage
Tanking and potential damage is rewarded. Potential damage is the sum of the maximum damage of all shells, bombs, torpedoes, etc. that hit the ship or pass within 700m.
For reference, there are 1,000 meters in 1km.
Earnings are modified by ship type. For example, battleships earn the most credits and base XP and aircraft carriers earn the least for receiving the same amount of potential damage.

Other Considerations
——————————————————————————————————————————-
The more Base Capture and Base Defense points you earn, the better.
Total rewards do not scale linearly. Destroying one cruiser earns full reward. Destroying two cruisers earns about 0.85 x gross reward. For destroying three cruisers, 0.67 x gross reward.
I say “about” because this is an approximation.
Diversity of activity is rewarded. For instance, a BB that camps at the back doing one task – shooting at long range – will earn less than the BB that accrues the same damage while shooting and also defending a capture point.
Achievements add hefty bonuses to the reward.
Each ship has multipliers to XP and credits. The multipliers of premium ships are known to be higher than those for tech tree ships.
The multiplier scales with the tier of the ship. For XP, a two-fold difference is possible between Tiers I and X. E.g. a Tier I ship may have a multiplier of 1.0 while a Tier X ship has a multiplier of 2.0. For credits, the difference is even greater.
Finally, the Base XP rewards increase greatly for the winning team.
This is perhaps the most important factor. Help your team win instead of farming damage in the back or by yourself, because you will likely have better reward results.
