What it means
Many people prefer to invest a little at a time instead of in one lump sum. A voluntary accumulation plan sets up a routine, such as $500 a month into a fund, but leaves the investor free to pause or end it.
There is no penalty for stopping, because the investor has made no legal promise to carry on. The contrast is with a contractual plan, in which the investor signs up to a fixed schedule of payments over many years.
Contractual plans have historically carried heavy upfront charges that were deducted in the early years. Voluntary plans generally avoid that structure, which is one reason they are more common now.
The regular investing approach has a built-in discipline. Because the same dollar amount buys more units when prices are low and fewer when prices are high, the average cost per unit tends to be lower than the average of the prices.
This is known as dollar-cost averaging. The plan does not guarantee a profit or protect against losses.
If the fund falls in value, the investor holds a smaller balance than was paid in, and stopping at the wrong moment can lock in a loss. Fees and the fund's charges still apply and should be checked before starting.
For the business reader, the same principle appears in employee savings schemes and in the way a treasury team might add to a reserve fund in steady instalments. It turns a large decision into a series of small ones and reduces the risk of committing everything at a poor moment.
Plan details differ by provider. Some require a minimum monthly payment, and some offer automatic reinvestment of dividends, so the terms should be read carefully.
In practice
Real-world examples.
Example
A young engineer sets up an automatic transfer of $300 a month into an index fund through a voluntary plan. When her car needs repairs, she pauses payments for two months and restarts afterwards. She faces no penalty and loses nothing for having stopped.
Example
A small business owner invests $1,000 a quarter from company profits into a bond fund as a long-term reserve. In a weak quarter he skips the payment. The flexibility suits the uneven cash flow of his business.
Example
A couple saving for their child's university costs invests $200 a month. After five years they raise it to $350 as their income grows. The plan allows them to change the amount at will without any fee for amending the arrangement.
Formula
Calculation
Future value of regular investments = Payment x (((1 + r)^n - 1) / r)
An investor puts $1,000 at the end of each year into a fund expected to grow at 10% a year, for 3 years. Using the formula, the growth factor is ((1.10)^3 - 1) / 0.10 = (1.331 - 1) / 0.10 = 3.31. Future value = $1,000 x 3.31 = $3,310. The investor paid in $3,000 in total, so the expected gain is $310, though actual returns could be higher or lower.Case study
Seen in the real world.
Linden Park Dental is an illustrative, fictional practice whose owner wanted to build a $60,000 equipment replacement fund. She had been tempted by a contractual savings plan but disliked the rigid commitment and early-year charges.
Her accountant suggested a voluntary accumulation plan into a balanced fund, with $1,000 invested each month. In a slow summer month she paused for 4 weeks, then resumed.
After four years the fund held roughly $55,000, helped by market growth. The fictional practice reached its target within a further few months, and the owner credited the flexibility for keeping her committed to the saving. She also asked her accountant to review the fund's charges each year and to confirm that the paused month had not triggered any fee. The review found nothing unexpected, which reinforced her preference for the voluntary route over a contractual one.
Watch out
Common mistakes.
- Assuming that voluntary means free of charges, when funds still carry management fees and possible sales charges.
- Stopping payments after a market fall, which can mean missing the cheaper purchases that make regular investing effective.
- Confusing it with a contractual plan, which binds the investor to a fixed payment schedule.
Questions
People also ask.
Can I stop a voluntary accumulation plan at any time?
Yes, because there is no binding commitment, though any fund exit charges still apply and should be checked.
Does the plan guarantee a return?
No, the value depends on how the underlying fund performs and can fall below the total paid in.
Is it the same as dollar-cost averaging?
It is a way to practise it, since regular fixed payments buy more units when prices are low and fewer when they are high.
