How pirate prize shares worked

A worked model of one reported rule—not an estimate of what a pirate earned.

AI-generated interpretation · not an archival image

Prize shares were weighted entitlements rather than necessarily equal payments per person. In Roberts’s reported articles, captain and quartermaster receive two shares each, the master, boatswain and gunner one and a half, and other officers one and a quarter. Other crews’ reported rules differ.

  1. 01A ledger, not an archive

    The book is blank and invented. It introduces accounting without fabricating a surviving pirate ledger.

  2. 02People are one count

    The teaching roster has sixty people. That number comes from the stated example, not from counting the decorative wooden counters.

    Published under the name Captain Charles Johnson
  3. 03Weighted shares are another

    The same roster totals 63.5 shares because the example assigns different multipliers to different offices.

  4. 04A unit is not a person

    Two differently sized counters make weighting visible. They are illustrative aids, not literal historical accounting equipment.

  5. 05Reported rule

    The printed Roberts Article X gives two shares to captain and quartermaster and one and a half to master, boatswain and gunner.

  6. 06Net distributable pot

    The default example starts with 6,350 accounting units available for division. A capture’s gross value would not automatically equal that amount.

  7. 07No identified currency

    The plain discs deliberately name no denomination. The model teaches proportions rather than converting historical money.

  8. 08One weighted share

    At the default pot, one share is 6,350 divided by 63.5: 100 units. The detailed model below shows the totals.

People and shares are different denominators

If sixty people divide a sum equally, the denominator is sixty. If some receive two shares or one and a half, first count the total weight of all entitlements. That denominator is larger than the headcount.

Roberts’s Article X, as printed in the General History, supplies the multipliers used here. It is a reported rule, not a complete payroll. Johnson also prints different arrangements for Lowther and Phillips. We therefore use a named rule and invented crew composition instead of claiming to calculate a typical pirate wage. [1]

The interactive model is deliberately narrow. You can change the net distributable pot; the hypothetical roster stays visible so you can inspect every assumption. Nothing is sent or stored.

Weights change the denominator.

The sizes of these invented counters are illustrative. Use the typeset roster—not the painted groups—to check sixty people, 63.5 shares and the multiplier assigned to each group.

The sixty-person teaching example

Suppose the distributable pot is 6,350 accounting units after any deductions. Our invented company contains a captain, a quartermaster, three officers at one and a half shares, and fifty-five people at one share. That makes sixty people and 63.5 shares.

Total60—63.5

One share is 6,350 ÷ 63.5 = 100 units. Each two-share officer receives 200; each one-and-a-half-share officer receives 150; each one-share participant receives 100. The total is 400 + 450 + 5,500 = 6,350. These numbers are arithmetic, not a documented payment.

What the model leaves out

Roberts’s reported rules also mention injury compensation from the public stock and higher shares for other officers. Our example has no additional quarter-share officers. It assumes the net pot is already known and does not deduct injury payments a second time. [1]

A real reconstruction would need the actual roster, the applicable rules, the goods available, any prior claims and a source for valuation. Without those, a beautifully precise currency figure is just a precise assumption.

Goods need not behave like a pile of interchangeable coins. Johnson describes a division involving diamonds, with shares adjusted for the size of stones. Even that account does not justify translating every prize into a clean modern cash salary. [1]

A pot has to be defined first.

The purse is a teaching image. Capture, valuation, deductions and distribution are different stages, so the calculator asks for a net distributable pot.

Shares were not guaranteed income

A promised share is a rule about entitlement if there is something to divide. It does not establish how often a company captured valuable goods, how losses were handled, or whether its members escaped with their shares. An earnings average needs evidence the rule alone cannot provide.

The same book includes desperate shortages, abandoned equipment, violent disputes and accusations of concealment. Those episodes are part of its picture of pirate life. A page that extracts only a multiplier and announces a lucrative wage has discarded the difficult half of its own source. [1]

For that reason, the model uses neutral accounting units. It offers no pounds-to-dollars conversion and no claim about present purchasing power.

Try the rule, then question the inputs

Change the net pot and watch the per-person amounts move together. The ratios remain the same because the share weights have not changed. If you want to change the crew, you must change the denominator too.

Read the source trail for the articles before using these figures elsewhere. Then return to crew responsibilities: the financial multiplier, the work performed and the authority exercised are connected but separate questions.

Questions, answered.

Did the captain take all the money?

Not under the reported Roberts rule used here: captain and quartermaster each receive two shares, while other members have specified entitlements. That is not a universal rule.

Are these real earnings?

No. The roster and net pot are invented teaching inputs. Only the stated share multipliers are taken from the attributed articles.
