Use CyborgPrime's Traveller Ship Mortgage Calculator to estimate starship debt, monthly payments, maintenance costs, and the campaign pressure created by owning a ship in Traveller or another sci-fi RPG.
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.

What This Calculator Estimates
This calculator estimates the monthly mortgage, monthly maintenance, and total monthly expense for a Traveller-style starship based on ship price and ship shares.
Use it when you want a fast table estimate for how much financial pressure a ship loan puts on the crew each month.
The result is not a full accounting ledger. It is a campaign-planning number that helps the Referee and players understand how expensive starship ownership can feel.
How to Use the Traveller 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.
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.
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.
Ship Debt as Campaign Pressure
A Traveller ship mortgage is not just bookkeeping. It gives the campaign a clock.
When a payment is due, the crew has a reason to look for freight, passengers, mail contracts, speculative cargo, patron jobs, salvage claims, risky shortcuts, and deals they might otherwise ignore.
That pressure is useful because it keeps the campaign moving without forcing the Referee to railroad the players. The crew still chooses what to do, but the debt makes doing nothing expensive.
Used well, ship debt creates decisions like:
- Do we take the safe cargo run or the dangerous high-paying job?
- Do we spend credits on repairs now or risk one more jump?
- Do we carry passengers even if they bring trouble aboard?
- Do we accept a patron job with strings attached?
- Do we stay legal, or does debt push us toward smuggling?
- What happens if the lender, port authority, or patron loses patience?
What Monthly Ship Debt Does to Play
Use monthly debt as a campaign tool, not just an accounting detail.
| Debt Pressure | What It Creates at the Table |
|---|---|
| Monthly payment | A recurring reason to find paid work. |
| Maintenance cost | A reason to care about repairs, breakdowns, and spare parts. |
| Missed payment | Collectors, penalties, legal trouble, or repossession threats. |
| High-risk cargo | A tempting way to make a payment fast. |
| Ship damage | A conflict between paying the lender and keeping the ship safe. |
| Ship shares | A reward that reduces pressure without removing it completely. |
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.
