CashCalc has come up with the tool, which aims to be the “most comprehensive inheritance tax planning calculator on the market”.
The firm, launched in May 2014, creates cashflow model tools, with an online suite of financial planning services including over 20 calculators.
Ray Adams, director of CashCalc and Wales-based Niche IFA, a firm of Chartered Financial Planners, said the IHT calculator was designed by planners, for planners.
He said it would make the complex task of inheritance tax planning “simple without sacrificing functionality”.
He claimed: “The level of information this calculator can provide clients is unrivalled – it certainly is out there on its own in the market”.
The firm listed the calculators features as:
• Calculate changing asset values, including mortgages, loans, equity release.
• Plan for married, single, widowed, and un-married clients.
• Specify first death and second death, including outstanding liabilities from first death.
• Include Residential Nil Rate Band Allowance and tapered Residential Nil Rate Band Allowance (after £2 million).
The company, which said over 3,600 financial advisers had used its tools, recently announced its integration with platform provider Transact.
