Narrowboat Finance Calculator
🚤 What Is a Narrowboat Finance Calculator?
A Narrowboat Finance Calculator is an online financial tool designed to estimate the cost of borrowing money to purchase a narrowboat. Whether you’re applying for a personal loan, marine finance, or secured lending through a broker, this calculator gives you:
- ✅ Estimated monthly repayment
- ✅ Total interest payable
- ✅ Total repayment amount
- ✅ A breakdown over the full loan term
It is ideal for buyers wanting to compare loan options before committing to any financial agreement.
🔢 What Information Does the Calculator Use?
To provide accurate figures, the calculator typically requires:
- Boat Purchase Price – The full cost of the narrowboat
- Loan Amount – The portion of the price you need to finance
- Down Payment / Deposit – Any amount you’re paying upfront
- Annual Interest Rate (%) – The cost of borrowing, expressed yearly
- Loan Term (Years) – The time over which you plan to repay the loan
Based on this information, it uses a standard amortized loan formula to estimate monthly payments and total interest over time.
📘 Formula Used in the Calculator
The calculator is based on the standard loan amortization formula:
Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n – 1]
Where:
- P = Principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term × 12)
It also calculates:
- Total Interest Paid = (Monthly Payment × n) – P
- Total Cost of Loan = Principal + Interest
🧮 Example Calculation
Example 1: Buying a Narrowboat for £70,000
- Down payment: £20,000
- Loan amount: £50,000
- Interest rate: 6% annually
- Term: 10 years
Calculation:
- Monthly repayment: £555.10
- Total interest paid: £16,611.61
- Total amount repaid: £66,611.61
With this data, the calculator helps determine if the repayment plan fits your budget or if you should consider a larger deposit or longer term.
