Barter

Barter is a Fallout, Fallout 2, Fallout 3, Fallout Tactics, Fallout: New Vegas and Van Buren skill.

The Barter skill is primarily used in the buying and selling of items, such as trading with a merchant or scavenger. In general, purchase prices will be lowered and selling price will be higher. It is the primary factor in price determination, and is also offset by the Barter skill of the non-player character in question. The skill is also used in certain dialogue options with non-player characters, where certain responses require Barter checks.

Fallout and Fallout 2

 * Fallout 1: $$\text{Initial level}\%=20+(2\times\text{Charisma})$$
 * Fallout 2: $$\text{Initial level}\%=(4\times\text{Charisma})$$

The skill only affects the prices for the vendor's items, the player character's items are always worth the same.

Having the Master Trader perk will give the player character an automatic 25% off all goods, and the Good Natured trait will provide a +15% to the Barter skill.

Barter is noticeably effective in Fallout & 2 in case of limited funds. With a low Barter skill, item prices may be as high as $800 for Rad-X and $32,500 for combat armor.

Fallout Tactics

 * $$\text{Initial level}\%=0+(4\times\text{Charisma})$$

The initial level for Barter is still governed by Charisma, but usually starts out lower than Barter in Fallout.

Barter also determines how much things can be sold for in Tactics, whereas selling prices were always static in the previous Fallout games.

Fallout 3
Barter Value
 * $$\text{Initial level}=2+(2\times\text{Charisma})+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Charisma of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=15$$

Derived Values
 * $$Sale~value~\% = 45\% + \left \lceil Barter \times 0.45\% \right \rceil \times Modifier$$
 * $$Buy~value~\% = 155\% - \left \lceil Barter \times 0.45\% \right \rceil \times Modifier$$


 * Modifier is normally 100%, but can go up or down in 10% increments. For example, being nice to Gob will have him pay at 120% and sell for 80% of normal.

A Barter skill of 11 allows the Lone Wanderer to sell at 50% of the rated value of an item. Each 5th point increase in score only increases sale prices by approximately 2.25 percent. A Barter skill of 86% is required to buy ammunition costing 3 caps at value from a normal merchant, while if having a 10% discount (e.g. in Rivet City) only 57 skill is needed, or with a 20% discount (possible with Seagrave Holmes & Bannon) a measly 21 skill works. However, the Barter skill does not reduce the charge for having merchants repair items.

A high Barter skill is a good choice for characters lacking Strength, since they do not have much room to carry many items and, subsequently, have less things to sell. However, having a companion partially negates this, since they can be given around 200 pounds of weight.

Available discounts

 * Master Trader - 25% discount with every trader in the game.
 * Craterside Supply - 30% discount upon receiving the Dream Crusher perk.
 * Moriarty's Saloon - 10% discount with Gob if he is treated nicely when initially meet.
 * Rivet City - 10% discount with all merchants in the city upon completing research into Rivet City's history.
 * Rivet City Supply - 10% discount depending on Lone Wanderer's choice during the quest Council Seat.

 * Lock and Load - 20% discount upon completion of Economics of Violence.
 * Federalist Lounge - 10% or 50% discount by hacking the nearby terminal.

Interactions that require Barter skill
A number of dialog based trading can be altered with sufficient Barter:
 * 50 Barter is needed to obtain a 1,000 caps discount from the initial price of 2,000, when buying Charon's contract from Ahzrukhal during the unmarked quest Hired Help.
 * 50 Barter needed to obtain a 500 caps rebate on the 1,000 caps price to buy Clover from Eulogy Jones in Paradise Falls.
 * 30, 50, or 70 are threshold which, once crossed, can each provide a better level of reward in the unmarked quest Zip's Nuka Fix in Little Lamplight.
 * 75 Barter will give a much better bargain when trading cave fungus for strange meat during the unmarked quest Fungus Deal in Little Lamplight.
 * An unknown amount of Barter is required to obtain a better deal from Abraham Washington when selling Lincoln's artifacts during the unmarked quest Lincoln's Profit Margins.
 * 70 Barter is needed to obtain Sergeant RL-3 from Tinker Joe for 500 caps instead of 1,000.

Ways to increase Barter

Fallout: New Vegas

 * $$\text{Initial level}=2+(2\times\text{Charisma})+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Charisma of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=2+10+3=15$$

Barter affects the prices gotten when trading with merchants. There are also many Barter skill checks in the game that can help advancing in quests by displaying a good sense with money, talking down costs, and talking up rewards. The Barter skill is governed by the Charisma attribute.

General price (before application of reputational fees or discounts) is counted with the same formula as in Fallout 3. Note that reputation does not affect prices unless that particular merchant is scripted to modify worth based on the Courier's reputation. For example, Chet will only use the PC's barter skill value to determine prices even if they are Idolized with Goodsprings, but with a mixed reputation (regardless of how good or bad it is), he will offer at 1:1 prices.

Barter in quests and exploration
While hard to tell in the abstract from the following list, in many cases Barter is offered as an alternative dialogue skill check to Speech (though generally involving paying money) or other skill checks. This may be to help compensate for the fact that Barter on its own may not be as useful as other skills.

Available Discounts

 * Goodsprings: Trudy will give the Courier a discount for saving the Goodsprings settler during Back in the Saddle, repairing her radio or helping the town during Ghost Town Gunfight. The discount is tied to becoming "Accepted" in the town, not any one specific act. The discount will be lost upon gaining infamy.
 * Goodsprings: Chet will give a discount with a mixed reputation in Goodsprings, but doing so will void the discount with Trudy. However, Chet has a much wider inventory and more caps than Trudy, making him arguably better for trading.
 * Goodsprings: Chet will give a discount after passing a Barter check of 25 if accepted the offer to help Joe Cobb take over the town.
 * Primm: Johnson Nash will give the Courier a discount for making Meyers sheriff.
 * Novac: Cliff Briscoe will give the Courier a discount only after speaking to Jeannie May Crawford about the Dino Bite gift shop and then telling him she sent the [Courier]. The discount will not be lost even if he finds out they helped kill her.
 * Old Mormon Fort: Julie Farkas will give the Courier a discount when they become "Accepted" with the Followers of the Apocalypse, further discounts resulting in 1:1 ratio when they join the Followers.
 * New Vegas medical clinic: 1:1 ratio when the Courier joins or becomes "Accepted" by the Followers.
 * Great Khan armory: the Great Khan armorer will give a 1:1 price ratio when Great Khan reputation becomes "Accepted."

 * Camp McCarran concourse: William Farber will offer the Courier a discount after repairing the food processor during Not Worth a Hill of Corn and Beans.
 * Hidden Valley bunker: When the Courier's reputation with the Mojave Brotherhood becomes Mixed, a paladin should approach them and inform them of a discount. This is currently bugged, however, so only the reputation discount is available.

Van Buren
In Van Buren, as in Fallout and Fallout 2, Barter did indeed have an effect on store prices. However, it also represented a certain level of knowledge about the caravan houses and trading in general, giving it a small role in dialogue. The intended depth to Barter development came in the perks available at higher skill ranks.

Fallout 3

 * Mister Burke (77) - Allistair Tenpenny's right-hand man, asking you to detonate the Megaton atomic bomb.
 * Leroy Walker (68) - Leader of 6-man squad of slavers who have occupied the Lincoln Memorial.
 * Victoria Watts (63) - The Railroad member, asking your help in protecting escaped android Harkness.

Fallout: New Vegas

 * Elizabeth Kieran (98) - NCR Major providing aid to NCR squatters living in Freeside.
 * Lady Jane (98) - a caravan merchant living in Freeside.
