What it means
Every long-term financial plan starts with an assumed rate of return, but the world rarely cooperates. Actual return is the after-the-fact measurement, and the gap between it and the expected figure is what drives many accounting adjustments and funding decisions.
The measurement has to be careful about cash flows. If a pension fund receives $900,000 of employer contributions during the year, that money increases the closing balance without being investment performance, so it must be removed before the return is calculated; benefits paid out must be added back for the same reason.
In pension accounting, actual return on plan assets includes realised gains, unrealised changes in market value, interest and dividends, less investment management costs. Standards then split that figure into an expected component that flows through profit and a remainder that is treated as an actuarial gain or loss.
Outside pensions, actual return is what investors mean by realised performance. It is the honest scorecard against which a manager's promises, a business case's projections or a treasury policy's assumptions are judged.
An important nuance is timing. Where money moves in and out unevenly during the period, a simple beginning-and-end calculation can be misleading, and analysts switch to a time-weighted or money-weighted return that reflects when each cash flow occurred.
A final point is that actual return can be quoted as a dollar amount or as a percentage, and the two answer different questions. The dollar figure tells you how much the fund actually grew, while the percentage tells you how hard the assets worked relative to the money invested.
Trustees usually want both, because a large dollar gain on a large fund can still be a weak percentage.
In practice
Real-world examples.
Example
A finance director reviewing the annual pension note sees actual return of 10% against an assumed 7%. The favourable difference reduces the reported deficit and is disclosed as an actuarial gain rather than as ordinary profit.
Example
A family business that parked $2,000,000 of surplus cash in a bond fund compares the actual return of 3.2% with the 4.5% the treasury policy assumed. The board rewrites the policy assumption and moves part of the balance into a shorter-dated deposit.
Example
A charity's investment committee measures actual return net of fees before renewing its fund manager's mandate. Two years of underperformance against the agreed benchmark trigger a competitive re-tender of the mandate. The committee also records the return in dollars alongside the percentage, so trustees can see the effect on next year's grant budget.
Formula
Calculation
Actual Return = Ending Value - Beginning Value - Contributions Received + Benefits or Withdrawals Paid. A company pension scheme starts the year with plan assets of $12,000,000. During the year the employer contributes $900,000 and the scheme pays $600,000 of benefits to retirees. The assets are measured at $13,500,000 at year end. Actual return = $13,500,000 - $12,000,000 - $900,000 + $600,000 = $1,200,000. As a percentage of opening assets that is $1,200,000 / $12,000,000 = 10%. The scheme had assumed a 7% expected return, which on $12,000,000 equals $840,000, so the actual result exceeded expectations by $1,200,000 - $840,000 = $360,000.Case study
Seen in the real world.
This is an illustrative scenario using a fictional business. Bramwell Engineering, an invented manufacturer with a legacy defined benefit scheme, had built its five-year cash plan on an assumed 7% return on $12,000,000 of plan assets. The finance team treated that assumption as though it were a fact.
In the illustrative year described here, markets ran hot and the actual return came in at $1,200,000, or 10%. The finance director was delighted until the following year, when the same portfolio produced an actual return of just $180,000, or 1.5%, and the funding deficit widened sharply.
The lesson the fictional board drew was that a single year's actual return tells you very little on its own. They moved to reviewing a rolling five-year average actual return alongside the assumption, and set a rule that contributions would only be reduced if the rolling average had beaten the assumption for three consecutive years.
Watch out
Common mistakes.
- Comparing the closing balance with the opening balance and calling the difference the return, without removing contributions and adding back withdrawals.
- Quoting actual return before investment management fees, which flatters performance and makes the comparison with a net-of-fee benchmark meaningless.
- Reading one strong year of actual return as evidence that the long-term assumption should be raised.
Questions
People also ask.
How does actual return differ from expected return?
Expected return is the assumption set at the start of the period, while actual return is what the assets genuinely delivered by the end of it.
Does actual return include unrealised gains?
Yes, changes in the market value of assets still held count towards actual return even though nothing has been sold.
Why use a time-weighted return instead?
Time-weighted return removes the distorting effect of large cash flows arriving mid-period, which makes it fairer for judging a manager's skill.
