Wealth Modeller is designed for people who want to understand how their financial decisions play out over time. Unlike simple calculators, it models cash flow, investments, property, mortgages and tax together in a single timeline.
You can test scenarios such as paying off a mortgage early, investing more aggressively, changing interest rates or accounting for inflation, then compare outcomes side by side.
The app is especially suited to UK users, with support for ISAs, pensions, rental property modelling and self assessment style tax calculations.
