How much interest could an offset account save?

Worked examples of offset interest reductions, why balances and timing matter, and how to interpret lifetime savings in the Sidelo calculator.

WHY SIDELO EXISTS

Saving feels different when
you can see where it leads.

Sidelo began as a tool its creator used to plan expenses, set a savings goal and see how those choices could change mortgage interest over time.

Seeing that connection helped make saving more purposeful. The aim is to make the same kind of clarity accessible to other people with a mortgage, free of charge.

It won’t tell you which loan to choose or what you should do with your money. It gives you a way to explore your own assumptions.

BEHIND THE NUMBERS

A useful estimate needs visible assumptions.

Daily interest, monthly savings, repayment timing and the comparison baseline: here is what Sidelo actually calculates.
