Ship mortgages, expenses, and ship shares can make Traveller starship ownership feel complicated. Use CyborgPrime's Traveller Ship Mortgage Calculator to estimate monthly mortgage payments, maintenance costs, and total monthly ship expenses.
Traveller Ship Mortgage Calculator
A ship mortgage is more than a number on a character sheet. It is campaign pressure.
If your Traveller crew owns a ship, that ship creates freedom, opportunity, debt, responsibility, and a reason to keep taking jobs. The mortgage payment is what turns a starship from background equipment into a recurring campaign engine.
This calculator helps estimate the monthly cost of owning a ship after accounting for ship price and ship shares.
A Ship Mortgage Can Be an Expensive Obligation
A ship mortgage is a loan from a bank or other lender that helps finance the purchase of a space vessel.
When you take out a mortgage, you promise to repay the credits borrowed, plus any agreed-upon terms. The ship itself is used as collateral. If the crew misses payments or defaults, the lender may charge penalties, seize assets, send collectors, or repossess the ship.
That makes a mortgage useful in play. It gives the crew a reason to haul cargo, carry passengers, chase speculative trade, accept patron jobs, take risks, and keep moving.
A ship with a mortgage is not just transportation. It is a business, a home, a debt obligation, and a source of adventure hooks.
How to Use the Traveller RPG Ship Mortgage Calculator
To use the calculator, enter the purchase cost of the ship in millions of credits.
If your character or crew has earned any ship shares, enter the number of ship shares in the calculator.
The calculator estimates:
- Monthly mortgage: The estimated monthly ship payment.
- Monthly maintenance: The estimated maintenance cost for keeping the ship operating.
- Total monthly expense: The mortgage and maintenance combined.
Please note: crew salaries, fuel, life support, berthing fees, docking costs, cargo purchases, repairs, insurance, bribes, fines, and passenger expenses are not included in this calculation.

What the Calculator Does Not Include
This calculator focuses on the mortgage and maintenance estimate. In an actual Traveller campaign, ship ownership usually includes many other costs.
Depending on the campaign, your crew may also need to pay for:
- Fuel
- Life support
- Crew salaries
- Berthing fees
- Docking fees
- Repairs
- Spare parts
- Insurance
- Licenses and permits
- Cargo purchases
- Passenger expenses
- Medical costs
- Fines, bribes, or legal trouble
This is why a ship mortgage works so well as a campaign driver. The ship creates freedom, but it also creates pressure.
Using Ship Debt as a Campaign Engine
A ship mortgage gives the crew a clear reason to take action.
When payments are due, the Travellers may need to find passengers, haul freight, chase speculative cargo, accept a dangerous patron job, take a mail contract, smuggle questionable goods, or risk a route they would normally avoid.
Good ship-debt pressure can create questions like:
- Can we make the next payment?
- Do we take the safe job or the profitable job?
- Do we trust this passenger?
- Can we afford repairs before the next jump?
- Should we haul freight, speculate on cargo, or accept a patron mission?
- What happens if the bank, lender, or patron loses patience?
- Do we stay honest, or does debt push us toward smuggling?
That is the fun of Traveller ship ownership. The ship gives the crew agency, but the bills keep them moving.

Give Your Traveller Crew a Ship Worth Paying For
A ship mortgage is not just a number on a character sheet. It is campaign pressure, a reason to take jobs, a source of recurring expenses, and a constant reminder that the crew needs to keep flying.
If your Traveller campaign revolves around a merchant ship, scout ship, free trader, or far trader, starship deck plans make that investment feel real at the table.
Use deck plans for crew quarters, cargo loading, repairs, boarding actions, passenger scenes, customs inspections, smuggling complications, emergency landings, and derelict exploration.
