About this tool

This is an experimental calculator builder. You describe what you want to calculate, and it tries to build it for you on the spot. It is pretty clever, but it is not perfect it can occasionally misunderstand what you are asking for, pick the wrong formula, or produce a result that looks right but is not quite. Think of it as a helpful starting point, not a final answer.

If you are planning to use any of the figures it gives you for a real financial decision a budget, a loan, a savings plan, anything that matters please take a moment to sense-check them yourself or run them past someone who knows their numbers. We are not financial advisors, and this tool is not a substitute for proper financial advice. It is just here to make the maths a little less daunting.
