When is the best time to start saving in a pension? The answer is simple – at the earliest possible moment. The first pound, euro, dollar or dirham you invest is the most valuable, as it has so much longer to grow in value. If you start in your twenties, it could be invested for 40 years or more, which means you have decades for compound interest to work its magic.

“You get growth upon growth upon growth, followed by more growth. The earlier you start the process, the more it will all roll up,” says Chris Davies, chartered financial planner at The Fry Group in Dubai.

This table shows how much you would have in your pension at age 65, depending on when you start and how much you pay in (it assumes your investments grow 7 per cent a year after charges and you have no other savings).
