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, the higher this skill level is, the lower prices will be when purchasing items, and the higher they will be when selling items. 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

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

Example: A starting Charisma of 5.
 * $$20+(2\times5)=30\%$$

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

Barter is noticeably effective in Fallout & 2 if you have limited funds. With a low Barter skill, item prices may be as high as 700 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 you can sell things for in Tactics, whereas selling prices were always static in the older 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, if you're nice to Gob he'll pay at 120% and sell for 80% of normal.

A Barter skill of 11 allows the player 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 you have 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 player characters with low 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 you can put around 200 pounds of weight on them.

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 you with a better level of reward in the unmarked quest Zip's Nuka Fix in Little Lamplight.
 * 75 Barter will give you a much better bargain when trading cave fungus for strange meat during the unmarked quest Fungus Deal in Little Lamplight.

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 you get when trading with merchants. There are also many Barter skill checks in the game that can help you advance 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.

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.

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.
