Compound growth builds 65% of pension pot value, Standard Life finds

Only one in four UK adults correctly identifies investment growth as the biggest driver of a pension pot's final value, even though compound returns account for roughly £65,000 of a typical £100,000 retirement fund, according to a Standard Life survey of 6,000 people aged 18 to 80.

"Contributions are important, but the real benefit often comes from giving those contributions time to grow and generate returns over decades," said Jenny Holt, customer savings and investment director at Standard Life. "This is why starting early can make such a difference."

The finance firm's analysis of official figures splits the £100,000 pot into £18,000 from individual contributions, £13,000 from employers and £4,000 from government tax relief, leaving compound investment growth to supply the remaining £65,000. The survey found 39 percent of adults blamed their own contributions for most of the value, 27 percent pointed to employer contributions and 8 percent to tax relief.

The gap widens sharply with delay. Standard Life calculates someone who starts work at 22 on a £25,000 salary and pays minimum auto-enrolment contributions — 4 percent individual, 3 percent employer and 1 percent tax relief — builds a £210,000 fund by age 68. Waiting until 27 under the same assumptions cuts the pot to £170,000 because the money has less time to compound, assuming 5 percent annual investment growth, 3.5 percent salary growth, 2 percent inflation and fees of 0.75 percent.

Compound growth works because returns stay inside the pot, generating further returns on a rising base. A small early contribution therefore has an exponential effect over a working life, even before an employer's matching top-up and the government's relief on contributions are counted.

The findings carry a practical warning for savers who fear their fund is falling short. Standard Life advises checking the current fund value and transfer value of existing pensions, since moving money can carry a penalty, and confirming whether a scheme is defined contribution — where the saver bears investment risk — or the increasingly rare defined benefit type that pays a guaranteed income. Savers should also ask whether any guarantees, such as a fixed annuity rate, would be lost on transfer.

Anyone worried about shortfalls can add a scheme's projection to the state pension, currently £241.30 a week, or nearly £12,550 a year, for those who qualify for the full new rate. Raising contributions, especially where an employer matches higher payments, and using the government's free pension tracing service to find lost pots are the other levers. Standard Life cautions that online searches for the tracing service surface many similarly named firms that charge fees or sell other products and could be fraudulent.
