Savings calculator

Compare simple cash and savings-account scenarios without needing a spreadsheet.

Choose the Savings tab in OneLine to compare cash and bank savings scenarios.

Cash

Model money held as cash with no interest.

Enter the AER advertised by your bank to estimate future value.

Try a fixed-rate scenario and compare it with your time horizon.

Before choosing a savings product, check the rate, access rules, introductory period, tax treatment and whether the advertised rate can change.

OneLine converts the AER you enter into an estimated monthly compounding rate and assumes it stays constant. Provider terms may differ.
