Calculator guide
Understanding Boat Slip Rental Return Calculator
Boat-slip return combines rentable slip-days, seasonal occupancy, rate, marina service cost, fees, fixed waterfront expense, debt, and dock reserve.
Calculation method
How the calculation works
Translate available boat-slip rental inventory and occupancy into used units, gross revenue, variable cost, platform fees, operating income, cash profit, break-even occupancy, reserve funding, and margin. Multiply sellable slip-days by occupancy and rate, subtract variable and platform cost, then cover fixed cost, debt, and reserve.

The dock diagram separates occupied, vacant, incompatible, and closed slips with the monthly return.
Worked situations
Practical examples
- A slip can be vacant because vessel dimensions are incompatible.
- Peak-season occupancy can conceal winter deficits.
- Utilities and liveaboard use can alter variable cost.
Better inputs
Useful tips
- Model slip sizes and contract types separately.
- Remove storm or repair closures from inventory.
- Fund dock and piling replacement.
Before relying on the result
Limitations and common mistakes
- One rate and occupancy apply to all slips.
