Nominal amounts, without adjustment for purchasing power. The chart deducts the purchase price and accrued interest. Principal repayments are not counted twice as costs. The balance equals cumulative cash flow after loan payments, less outstanding debt. Payback within a year is approximate.

Select including VAT if input VAT cannot be recovered. The adjustable VAT rate applies to the purchase, transport/installation and accessories. Enter rent, rental discounts and running costs as the income actually available and costs actually borne; these figures are not automatically converted.

2% is an editable example assumption, not an inflation forecast. Inflation does not automatically lead to higher rents. Increases apply to rent and additional running costs from year 2. The rental discount remains constant.

How the calculation works

Income equals monthly rent × months rented. From year 2, rent and additional running costs increase according to your assumptions. The rental discount remains constant. The chart balance is the sum of operating surpluses less the initial investment and interest accrued to that date.

The loan amount is the investment less your own contribution. Equal monthly payments are calculated using monthly nominal interest and payments at the end of each month. At 0% interest, the payment is the loan amount divided by the number of monthly instalments. Calculations use unrounded values; displayed monthly payments are rounded to cents. Cash available in year 1 equals the operating surplus less loan payments. Excludes income taxes, residual value, fees and replacement investments. A 30-year period is a calculation scenario, not a guarantee of service life or future costs.
