About this tool

We built this ShareSave (SAYE) calculator for four FTSE 100 employers, each deployment branded to match the company's employee benefits microsite. Employees pick a 3 or 5-year plan, enter a monthly savings amount, and explore future share price scenarios without wading through scheme documentation.

The calculator applies the correct bonus multiples, works out how many shares they could buy at the option price, and projects value + profit at different price increases, including a CGT note when gains cross the £3,000 threshold.

Each deployment pulls a live share price from APIs we built and maintain, so the current share price stays accurate without manual updates. We ship it as a self-contained widget that slots into each client's microsite: matching visual language, copy, and calculation logic for that brand.

The demo above uses illustrative option + share prices so you can explore the interface. Production deployments query our APIs for live pricing. Figures remain illustrative: share prices move, tax rules change, and individual circumstances vary.
