THE SAVINGS CALCULATOR

Do the maths before the detour.

Compare two fills, account for discounts and extra distance, then see what repeated savings could mean.

Enter only discounts you qualify for. Extra spend means purchases you would not otherwise make, plus relevant fees. Time, wear, tax treatment and points value are excluded. Use the same compatible fuel grade.

How the calculation works

Station cost = litres × (pump price − eligible discount) ÷ 100 + extra spend / fees. Detour fuel cost = extra return kilometres × consumption ÷ 100 × travel fuel price ÷ 100. Net saving at B = A total − B total − detour fuel. Annual scenario = net saving × fills per year × vehicles. Negative results mean B costs more. Calculations use unrounded values and round only for display.
