Bitcoin DCA Calculator — Dollar-Cost Average BTC
Same weekly-buy story as the DCA calculator, with Bitcoin as the default.
Guide
How do you calculate a Bitcoin DCA plan?
You buy a set dollar amount of Bitcoin on a regular day. This calculator adds those buys up. It shows cash you spent, how much BTC that bought, and what that BTC is worth at a price you type. It does not pull a live ticker.
Bitcoin dollar-cost averaging is a cash habit, not a promise. Put in $100 every Friday for a year: 52 buys, $5,200 spent. If your average fill from the exchange is $40,000, you hold about 0.13 BTC. At $50,000 that pile is worth about $6,500 — about $1,300 more than you spent, before tax. If Bitcoin were $30,000, the same coins would be worth about $3,900. Monthly buys are usually enough. Buying on the Bitcoin network every day mostly adds fees. Selling is a separate taxable event in most countries. Live widgets go stale; your fill history does not.
Example
Bitcoin DCA example: $100 every Friday
- Each Friday
- $100
- A year
- 52 buys
- If BTC is $50k
- $6,500
That $6,500 is what the pile is worth today on paper. It is not cash in the bank until you sell. Use the profit calculator when you close a single lot.
| Step | In words | Example |
|---|---|---|
| 1. Cash in | Amount each time × how many times | $100 × 52 = $5,200 |
| 2. Coins | Cash in ÷ average price you paid | $5,200 ÷ $40,000 = 0.13 BTC |
| 3. Value today | Coins × the price you want to check | 0.13 × $50,000 = $6,500 |
| Up or down | Value today minus cash in | $6,500 − $5,200 = $1,300 |
Limits
What this Bitcoin DCA calculator cannot do
- It will not pull a live Bitcoin price.
- It will not tell you that Bitcoin always goes up.
- It will not handle a one-off sale — use the profit calculator for that.
If you want the same habit without a Bitcoin default, use the main DCA calculator. If you later sell a lot, use profit.

FAQ
Questions people ask
Add up the cash you put in (amount × number of buys). Divide that by the average Bitcoin price you actually paid to get how much BTC you hold. Multiply that by the Bitcoin price you want to check.
Only if the price you check against is higher than the average you paid, after fees. Many long stretches of weekly Bitcoin buys have ended up ahead. Any single year can still be down. The calculator reports your numbers, not a slogan.
Average buy: the average from your exchange history. Current: the price on your app, or a round number you want to test. Not a target from social media.
Monthly is enough for most people. Weekly helps if you get paid weekly. Buying on-chain every day usually wastes money on fees.
Usually not until you sell, trade, or spend it. A green number here is a paper gain. Tax software is for the year you actually sell.
No. Type the average fill from your exchange and the price you want to check. Live widgets go stale.
Type the number of buys you actually made, not 52 out of habit. The cash-in figure should match your statements.
No. It is a snapshot at the price you typed. If Bitcoin is cheaper tomorrow, the pile is worth less.
