Each one has simple sliders, an instant result and a chart, plus a plain-English note on how the answer was worked out. All free, all private.
The numbers here are examples. Interest rates, tax bands and every result are sample starting points or values you type in yourself. Nothing is pulled from a live rate feed or a bank, and the results are estimates only. Always check real figures with your bank, lender or a qualified adviser before making a decision.
