Calculators

Work the number out on the page, then take the Excel version away.

Start hereSection 24 CalculatorMortgage interest is not a deduction. You are taxed on rent less running costs, then handed a 20 per cent reduction, and this works out what that actually costs you.Taxed on £20,000, keeping £5,000, owing £3,946At £17,000 of interest the tax passes the whole profitThe reduction worked as the lower of three, carry forward includedCalculator plus Excel Property Income Tax CalculatorYour rental profit on this year's rates and on the 22, 42 and 47 per cent property rates that arrive on 6 April 2027. Two points at every band, because rent carries no National Insurance.Calculator plus Excel Rental Yield CalculatorGross yield is rent over the asking price and nothing else. On the demo the advertised 9.23 per cent becomes 6.96 once the costs, the voids and the buying costs are counted.Calculator plus Excel Personal or Company LandlordA company still deducts its interest, worth £2,996 a year on the demo. Moving an existing property in costs £33,364 first, which is about eleven years of the saving.Calculator plus Excel Capital Gains Tax on PropertyThe base cost built line by line, the gain split across 18 and 24 per cent, and the 60 day clock that starts at completion. The exemption is £3,000 now, down from £12,300.Calculator plus Excel SDLT Surcharge CalculatorFive points on every band including the nil rate one, so a £250,000 flat costs £2,500 as a home and £15,000 as a rental. England and Northern Ireland.Calculator plus Excel Rent a Room or Let It Properly£7,500 tax free, or your costs, not both. The sheet compares the two methods and elects whichever leaves you taxed on less, year by year.Calculator plus Excel Void Period Cost CalculatorSix weeks empty costs 2.7 months of rent, not 1.4, because the mortgage, the council tax and the re-letting fee do not pause when the tenant leaves.Calculator plus Excel Mortgage Rate Rise Stress TestInterest is not deductible, so you feel about 80 per cent of any rise. On the demo portfolio 8.5 per cent turns a profit into a loss with the rent unchanged.Calculator plus Excel Repair or Improvement CheckerThree questions decide whether work is deducted now or waits for the sale. The same £9,000 is worth £3,600 as a repair and £2,160 as an improvement, years later.Calculator plus Excel
