Value Averaging vs DCA: Another Way to Invest on a Schedule
Value averaging vs DCA, with a worked crypto example: how VA sets a target value path, why its returns look higher than they are, and the cash reserve it needs.
Key takeaways
- DCA invests a fixed amount each period; value averaging invests whatever it takes to keep the holding on a preset target path.
- In our 6-month example, VA's return looked far higher (65.03% vs 40.71%), yet dollar profits were nearly the same.
- Compared on the same $1,500 budget, classic VA, no-sell VA and DCA all ended within $22 of each other.
- VA needs a cash reserve: in a falling path it required $2,107.16 instead of DCA's $1,500, with one month at $431.82.
- Classic VA sells when the holding runs ahead of target, which can add fees and, depending on where you live, taxable events.

What is value averaging?
Value averaging (VA) is a scheduled investing method in which the target is the value of your holding, not the amount you put in. The method comes from Michael Edleson, who in his 1991 treatment suggested monthly or quarterly steps. You decide in advance how much the holding should be worth after each period, say $250 more every month, and then invest whatever it takes to reach that target.
The rules are simple to state:
- Below target: buy enough to bring the holding up to the target value.
- Above target: in the classic version, sell the excess. In the no-sell variant, which Edleson later suggested as a way to reduce costs, you simply skip that period.
Compare that with dollar-cost averaging, where the amount is fixed and the value is whatever the market makes it. DCA automatically buys more coins when prices fall; VA goes further and invests more dollars too.
How to calculate each value averaging buy
Each period needs one line of math: VA buy = target value − (coins held × current price). A negative result is a sell signal in the classic version, or a skipped period in the no-sell version. The target path can rise by a fixed dollar amount, as in the example below, or by a percentage each period. Write the path down before you start, because changing targets midway turns the method back into guesswork.
A worked example: value averaging vs DCA on the same path
Suppose your target is for a hypothetical Coin B holding to grow by $250 a month, and the price moves through a dip and a rally over six months. The DCA investor puts in $250 every month regardless.
| Month | Coin B price | VA target value | Value before buying | VA buy (sell) | DCA buy |
|---|---|---|---|---|---|
| 1 | $20 | $250 | $0.00 | $250.00 | $250 |
| 2 | $16 | $500 | $200.00 | $300.00 | $250 |
| 3 | $12 | $750 | $375.00 | $375.00 | $250 |
| 4 | $15 | $1,000 | $937.50 | $62.50 | $250 |
| 5 | $21 | $1,250 | $1,400.00 | ($150.00) sell | $250 |
| 6 | $24 | $1,500 | $1,428.57 | $71.43 | $250 |
Month 2 shows the mechanism. The 12.5 coins bought in month 1 are now worth 12.5 × $16 = $200, which is $300 short of the $500 target, so VA invests $300. In month 5 the rally lifts the holding to $1,400, which is $150 above the $1,250 target, so the classic version sells $150.
- DCA, $250 a month 1.5k
- Value averaging 909
After six months, the results compare like this:
| After month 6 | Classic VA | VA, no selling | DCA |
|---|---|---|---|
| Net cash invested | $908.93 | $987.50 | $1,500.00 |
| Coins held | 62.5000 | 66.6667 | 87.9464 |
| Value at $24 | $1,500.00 | $1,600.00 | $2,110.71 |
| Profit | $591.07 | $612.50 | $610.71 |
| Return on cash invested | 65.03% | 62.03% | 40.71% |
Why value averaging’s returns look better than they are
At first glance, VA wins easily: 65.03% against 40.71%. Look at the profit row, though. All three approaches made roughly $600. VA’s percentage is higher mainly because it put less money to work, not because it made more money.
The fair comparison gives each method the same $1,500 budget and counts the unspent cash. The classic VA investor holds $1,500 of Coin B plus $591.07 never invested, $2,091.07 in total. The no-sell investor has $1,600 plus $512.50, or $2,112.50. The DCA investor has $2,110.71. Measured on the same budget, all three ended within $22 of each other.
This is the effect Simon Hayley of Cass Business School describes in a 2014 paper. Because VA invests more after poor returns and less after good ones, it mechanically raises the internal rate of return, but in his analysis it did not raise expected profits, and he concludes that VA is an inefficient strategy. The same trap appears whenever you compare money-weighted returns across plans that invest different amounts, as time-weighted vs money-weighted returns explains.
The cash reserve problem
VA’s contributions are unpredictable, and they grow exactly when markets feel worst. Edleson’s design assumes you keep a “side fund” of liquid assets to meet those calls.
Run the no-sell version through a steady decline, with Coin B at $20, $17, $14, $11, $9 and $8. The monthly buys become $250.00, $287.50, $338.24, $410.71, $431.82 and $388.89, for a total of $2,107.16, while DCA would have invested $1,500. VA needed 40.48% more cash, one month’s buy reached 1.73 times the base amount, and the holding was still only worth its $1,500 target at the end. That is a loss of $607.16, compared with DCA’s $485.46.
In crypto, where declines can be deep and long, a VA plan without a funded reserve tends to break at the worst moment. If you use one, decide in advance where the side fund sits and what happens when it runs out, for example by capping each buy at a fixed multiple of the base amount. A reserve held in stablecoins has its own risks, which stablecoin allocation covers.
Value averaging vs DCA at a glance
| Feature | Dollar-cost averaging | Value averaging |
|---|---|---|
| Amount per period | Fixed | Varies with the price path |
| Cash reserve needed | No | Yes, a side fund for large buys |
| Sells when prices run up | Never | Classic version: yes |
| Effort per period | None once automated | A calculation every period |
| Measured % return | Lower-looking | Higher-looking, partly a measurement effect |
| Extra costs | Fees on each buy | Fees on buys and sells; sells may be taxable |
The selling feature deserves a second look. Trimming a holding that runs ahead of plan resembles portfolio rebalancing, and some investors value that discipline. But every sale adds fees and, in many countries, a taxable event. Rules vary by country; check with a qualified professional before using a strategy that sells regularly.
A decision checklist before choosing value averaging
VA only fits if you can answer yes to all of these:
- You have a cash reserve, separate from emergency savings, that can cover buys well above your base amount for several months in a row.
- You are willing to calculate and place a different order every period, because a standard fixed-amount recurring buy cannot follow a VA schedule.
- You have decided whether you will sell above target, and you understand the fees and possible tax consequences.
- You will judge the result by total dollars, including unspent cash, not by the percentage return.
If any answer is no, fixed-amount DCA delivers most of the same averaging effect with far less effort. You can model that fixed-amount baseline in the DCA calculator, and check your blended purchase price with the average cost basis method.
The bottom line
Value averaging invests to hit a target value path, buying more in dips and less, or even selling, in rallies. Its higher percentage returns mostly reflect investing less money, and on the same budget our example ended within $22 of plain DCA. The real costs are a cash reserve, more work each period and possible sales, so it only works for investors who can fund and follow those rules.
Frequently asked questions
What is the difference between value averaging and dollar-cost averaging?
Dollar-cost averaging invests the same dollar amount every period, so the number of coins varies with the price. Value averaging sets a target for what the holding should be worth each period and invests whatever amount reaches it, which means larger buys after price drops, smaller buys after gains and, in the classic version, sales when the holding runs ahead of target. VA reacts more strongly to price, but it needs a cash reserve and more work.
Does value averaging beat DCA?
It often appears to, because its percentage return is measured on less invested cash. In this article's example, VA showed 65.03% against DCA's 40.71%, yet profits were about $600 for both, and on the same $1,500 budget all versions ended within $22 of each other. Research by Simon Hayley found that VA raises the internal rate of return without raising expected profits, and he concluded it is an inefficient strategy.
How much cash reserve does value averaging need?
There is no fixed figure, because contributions depend on the price path. The deeper and longer a decline, the more VA asks you to invest. In this article's steady-decline example, six months of VA needed $2,107.16 instead of DCA's $1,500, with one month at 1.73 times the base amount. One way to limit the risk is to cap each buy at a set multiple of the base amount, so a long slide cannot drain the reserve.
Can you do value averaging without selling?
Yes. The originator of the method, Michael Edleson, suggested that investors could reduce costs by delaying or ignoring sell signals. In the no-sell variant you simply skip any period where the holding is above target. In this article's example the no-sell version ended with 66.6667 coins and $612.50 of profit, compared with 62.5 coins and $591.07 for the classic version, but outcomes depend on the path.
