Financial decisions
Not a calculator that works out one number, but a tool that puts two options side by side and shows how each would turn out on your own figures.
You will not get a recommendation. You get both paths, the point where they cross, and a clear statement of which part of the result is certain and which is only your assumption.
Invest or repay the mortgage
You have spare money and a mortgage. Compare how an overpayment and investing would each turn out, on your own figures.
CompareHigher payment vs. longer term
What a lower monthly payment really costs once the term is stretched by ten years.
CompareRent vs. buy
Rent and invest the difference, or buy your own? A comparison of net worth over the years, not of the monthly payment.
Compare
In preparation
Lump sum vs. regular investing
Put the whole amount in at once, or spread it across monthly contributions? Both approaches compared on the same capital.
Repay early vs. invest
A single lump sum overpayment, or investing that same money steadily over the years.
Rate fixation: shorter vs. longer
What you pay for the certainty of a longer fixed rate, and when that certainty is worth the price.
Cash in the bank vs. investing
What inflation does to money left in a current account, and what the market would have done with it.
