What is the Narrowboat Retirement Calculator?
The Narrowboat Retirement Calculator helps you assess whether selling a house and living on a narrowboat can fund an early retirement, career break or alternative lifestyle without putting long-term financial security at risk. It models the full journey from house sale and boat purchase through to pension-backed retirement, all in today’s money.
How the Calculator Works?
This calculator uses a bridge-to-retirement framework. It models your finances year by year from today through pension access and into later retirement, separating the plan into distinct phases.
During the narrowboat phase, it tracks living costs, mooring strategy, maintenance cycles and any ongoing income. Assets continue to grow in real terms, and withdrawals are made only when spending exceeds income. Once pensions become accessible, the model transitions into retirement drawdown and later incorporates the UK State Pension.
You can also model a future “settle down” point where narrowboat living ends and spending switches to more conventional housing costs. All figures are inflation-adjusted so you can see real purchasing power rather than inflated future values.
Step One: Set Your Timeline and Assets
Enter your current age, pension access age, State Pension age and end age. Add your existing cash, investments and pension balances, along with the upfront cost of buying a van.
Step Two: Configure Narrowboat Living
Choose your mooring strategy, upfront boat costs, ongoing running costs and major maintenance schedules. Add any income you expect during this phase.
Step Three: Review Sustainability and Retirement Outcomes
See whether your assets can fully fund the bridge period, support retirement drawdown and remain sustainable through later life. Review milestone markers, asset usage and year-by-year results.

What is the Narrowboat Retirement Calculator?
It is a UK-specific planning tool that models whether selling a home and living on a narrowboat can fund an early retirement or career break while remaining financially sustainable into later life.
What does this calculator help me decide?
It helps you assess whether narrowboat living can replace traditional housing costs and support early retirement or a career break without running out of money later.
Does it assume I sell my house?
Yes. The default model assumes house sale proceeds fund the initial asset pool, but values can be adjusted to reflect your situation.
What mooring strategies are supported?
You can model constant cruising, a permanent home mooring or a mixed approach including winter moorings.
Are major maintenance costs included?
Yes. Periodic costs such as blacking, engine overhauls and replacements are explicitly modelled.
Can I include income while living on the boat?
Yes. Multiple income sources can be added with custom start and end ages and real growth rates.
Does it include pensions and the State Pension?
Yes. Defined contribution pensions, defined benefit pensions and the UK State Pension are all supported.
How are assets drawn down?
Withdrawals follow a tax-efficient order, using cash first, then ISAs and GIAs, and pensions once accessible.
What does “bridge years fully funded” mean?
It means your non-pension assets and income are sufficient to cover spending until pension access age.
What happens when I settle down later in life?
At the settle-down age, spending switches from narrowboat costs to conventional housing and living costs, which are then tracked through retirement.
Is my data stored?
No. All calculations run locally in your browser and no data is sent to servers.
Can I export the results?
Yes. You can download a CSV file with the full year-by-year projection.
