What is DCA strategy and how does it work?
Dollar-cost averaging (DCA) is investing with a fixed amount of money over a regular period of time, regardless of the market price at that time.
The benefits of DCA
Market Timing Risk
Create consistent investment discipline.

Reducing the psychological impact of market volatility.
DCA sample 10 year
Investment per month 5,000 baht Average return 8% per year for a period of 10 years (120 months):
Total cost: 5,000 × 120 = 600,000 baht
Port Value: Approximate 918,000 baht
Profit: Approximate 318,000 baht (53%)
Frequently asked questions
What is Dollar-Cost Averaging?
DCA is a strategy of investing with a fixed amount of money every month, like every month, regardless of market prices. When high prices get less units, when low prices get more units, making the average cost lower than buying one time at high prices.
What is DCA good for?
DCA is suitable for volatile assets with long-term growth, such as stock funds, index funds, individual stocks, and cryptocurrencies. Not suitable for permanent deposits with unvolatile prices.
DCA or lump sum?
In long-term growth markets, single-time investments tend to yield higher returns than DCA because all the money works from the start, but DCA reduces psychological risk and is suitable for regular earners who don't have a lot of money.
How many years do you need to do DCA to see results?
DCA is clearly effective in the long term, 5 years or more, and the longer you see the power of interest-duplicating, doing DCA continuously for 10-20 years in long-term equity funds tends to yield much higher returns than deposit interest.

How to use the Cost Average DCA Calculator
Use this page to test a specific average dca scenario. Enter your own values in the calculator above, review the units beside each field, and recalculate after changing an assumption. The result updates the cost average dca estimate instead of relying on a generic example.
Build a baseline average dca case with figures that match your situation.
Run a second average dca case after changing the rate, period, quantity or other key assumption.
Record the difference between the two average dca results and the input responsible for it.
Inputs for the average dca estimate
For this average dca calculation, check the quantities, rates, period, units and other assumptions requested on the page. The result is designed to show a investment and time value estimate for your scenario, not a guaranteed provider price or official decision.
How the average dca result is calculated
The calculator projects value over time from the entered amount, rate, period and contribution assumptions. Reusing the same average dca inputs will produce the same estimate, which makes the page suitable for controlled scenario comparisons.
Checks for a average dca decision
Confirm any current rate, threshold or provider rule that could change the final amount. For average dca, Use the result as a planning estimate and confirm any rate, rule or threshold that may have changed before acting. Check the important inputs and any current provider or authority rules before using the result for a decision.
