Second home typical annual costs: mortgage 12,000, local property tax 3,000 (premium), utilities 2,000, maintenance 3,000, insurance 800 = 20,800/year. Works out 400/week, 57/night. Self-catering equivalent 1,500/week peak — might be cheaper to holiday let.
A worked example
Try the defaults: mortgage of 12,000, local property tax of 3,000, utilities of 2,000, maintenance of 3,000. The tool returns 20,800.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Mortgage (annual), local property tax (annual), Utilities (annual), Maintenance (annual), and Insurance (annual). Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
The formula behind this
Sum of annual costs. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the headline rate hides
Lenders quote a rate; what you pay is a blend of that rate, fees, insurance, and any early-repayment penalty built into the product. The figure here isolates the core interest cost so you can compare like-for-like across deals — then add the other costs separately before signing anything.
What this doesn't capture
The figure excludes arrangement fees, valuation costs, legal fees, insurance, and any early-repayment charges — those can add several thousand to the headline cost. Rate changes at renewal for fixed-term deals will shift the picture further. Use this for the core interest/principal math and add the other costs on top.
