Calculators
Each calculator is a pure function of its inputs. Adding another one later does not require a new data model for programmes.
Points value
Turn a cash price, reward charges and points redeemed into pence per point. Optional fields cover points you forgo and a transfer ratio.
BA tier points
Estimate British Airways Club tier points for 2026–27 and 2027–28, including whether booking before 25 November 2026 matters.
