Big questions

Should I overpay my mortgage or invest the money instead?

Spare money each month and a mortgage to match: should you throw it at the loan or put it to work in the market? It is one of the most argued-about questions in personal finance, and the honest answer is that it depends on your rate, your timeframe, and your assumptions. Doughsense lets you stop arguing in the abstract and compare the two futures directly.

The shape of the answer

The journey builds both futures for you from three questions:

  • Which mortgage are you weighing up? Pick the loan, and its real rate and term come with it.
  • How much could you put in each month? The same surplus is applied to both paths, so the comparison is fair.
  • Where would you invest instead? Choose the account, and its growth assumption carries into the projection.

Then the answer puts the two paths next to each other: the same money overpaying the mortgage in one future and invested in the other, projected forward so you can see where they diverge and which leaves you ahead.

What you end up with

Two concrete futures, on your numbers, with the trade-offs visible: guaranteed interest saved on one side, uncertain but potentially larger growth on the other. You decide with the maths in front of you, and the direction you choose can be kept, so it becomes part of your real plan rather than a scenario you have to rebuild.

The growth and return assumptions are yours to set, and we are open about how the projections and simulations work, so nothing about the comparison is hidden.
