The Cyclesheme calculator is only designed for the case where the salary sacrifice (hire) period is 12 months (which is the default period for the scheme). If you hover over the question mark next to "when do you want to own your package?" (where you select "4 years" or "1 year"), it says: "At the end of your Hire Period you will need to select an Ownership Option. We recommend you choose the 4 year ‘Own it Later’ option as this will increase your savings." This option has an effect on the overall cost (the 1 year option is more expensive). There is no option in the Cyclescheme calculator to vary the salary sacrifice period.
