Every milestone (retiring, a sabbatical, an inheritance, downsizing, care) lives on one draggable line. Grab an event from the tray, drop it on an age, and the whole plan recalculates around it. Drag it again to move it; drop it off the line to remove it.
Play out your life.
As many times as you like.
PlanBox models UK tax, pensions and the State Pension all the way to one hundred, for the whole household: two retirement ages, the mortgage.
Most planners stop at retirement. PlanBox treats it as halftime.

Open each one. They all move together: change anything, and every view updates at once.
Where the money comes from.
PlanBox is free to play with. A few advanced features (unlimited plans backed up in the cloud, the full side-by-side Compare view) sit behind a small Pro tier you can take or leave. And if we ever point you toward a pension provider or an adviser, we'll show you exactly how we're paid for it, on the same page. The numbers come first. Always.
Your next sixty years are one drag away.
Open the sandboxOr skip the blank page: load a starter plan - a young renter, a family with a mortgage, or DINKs at 40 - and make it yours.
