Live path-shape dial and deploy ramp - so a finish price never pretends to be the whole journey.

01
Dollar-cost averaging (DCA) buys a fixed dollar amount on a schedule. Most crypto explainers stop at “buy every month” and then race DCA vs lump sum to a finish line. That race matters — but it hides a quieter variable: the shape of the price path between your start price and your end price.
This page’s framing is Path ≠ finish. Finish is the pair of endpoints you type (start price → end price). Path is every month in between. Two journeys can share the same finish and still mint different average costs and different coin bags, because DCA samples the middle.
That is a different job from the SIP calculator, which owns Flat ≠ step-up contribution twins on a fiat schedule, and from crypto P/L, which owns Mark ≠ basis across lots you already hold. Here we stay on how the path between two prices changes what a drip buys.
Decision framing: “Which middle am I assuming?” — not only “Did DCA beat a day-one lump?”
02
The unique affordance is the path-shape dial. Keep total budget, months, start price, and end price fixed. Flip between Steady path, Rally then chop, Bleed then recover, U-bottom, and Late spike. Endpoints pin; the middle flexes.
Rally-then-chop spends more months above the linear bridge early — DCA buys fewer coins than a calm climb. Bleed-then-recover does the opposite: early discounts raise the bag. U-bottom stresses the mid-window trough. Late spike keeps prices near the start longer, then sprints to the finish — back-loaded buys dominate.
Treat shapes as stress stories, not forecasts. The educational win is seeing that the same finish is not the same journey.
03
Avg cost at the end is a finish-line number. Mid-schedule you also care about how much cash is already deployed versus still waiting in fiat. Waiting cash is not yet price risk; deployed cash is.
Scrub the deploy ramp to any month. Read cash deployed, cash waiting, coins so far, and average cost so far. The fill meter is committed capital — not a twin bar against lump sum, and not a rate ladder. It answers: “How exposed am I halfway through this plan?”
04
Each month buys the same dollar amount at that month’s path price. Coins accumulate; average cost is total cash deployed divided by coins held. End value marks the full bag at the finish price you set.
Path shapes only reshape intermediate prices; month 1 and month N are pinned to your start and end inputs. A one-line vs-lump footnote (buy everything at start price, mark at end) sits under the verdict for context — it is not a Flat≠step-up twin UI.
05
The sketch ignores exchange fees and on-chain gas so path effects stay visible. In live markets, a weekly micro-drip can leak more in fixed costs than a monthly buy of the same monthly budget. If you settle on L1, open the gas fee calculator and ask whether the drip still makes sense after fee drag.
Volatility context belongs next door: path shape is a narrative; realized chop is a statistic. Pair with the crypto volatility calculator when you care how wild the middle might be — not when you only need Path ≠ finish literacy.
06
Scenario A — BTC bleed→recover. $6,000 over 12 months, $60k → $90k, bleed-then-recover shape. Early months buy more coins than a steady climb with the same finish. Scrub the ramp to month 6: half the cash is still waiting while avg cost already reflects the dip.
Use the BTC bleed→recover preset. Flip to Steady path with the same endpoints and watch avg cost and end bag move — finish unchanged, path changed.
Scenario B — ETH rally→chop. $3,000 over 10 months, $2,000 → $3,200. Front-loaded highs punish DCA relative to an early lump footnote. The point is not “never DCA”; it is that a bullish finish can still be a hostile middle for drip buyers.
Scenario C — Late spike. Quiet months near the start price, then a sprint to the finish. Most coins buy late; avg cost hugs the finish more than a U-bottom would. Deploy ramp near month 12 of 16 still shows a large waiting balance — exposure arrived late by design.

Share links snapshot total, months, start, end, path, and deploy month. Live typing never rewrites the address bar.
09
Stop here for Path ≠ finish literacy: same endpoints, different middles, plus how capital deploys through time. Hand off when you need lots, fees as the primary object, or fiat contribution step-ups.

Finish is your start and end prices. Path is the sequence of prices between those two points. Dollar-cost averaging buys along that sequence, so two journeys that share the same finish can still produce different average costs and coin bags.
No. The panel is an educational sketch: you set start price, end price, months, and a path shape. It does not pull live candles or backtest an exchange. Use it to understand path sensitivity, not to claim a historical return.
Lump-sum vs drip is a useful footnote, but the unique job here is path shape: same finish, different middles. Finance SIP already owns flat vs step-up twins. Crypto P/L owns lots at a mark. This page stays on Path ≠ finish and the deploy ramp.
It shows how much of your planned cash is already spent versus still waiting, plus coins and average cost so far at a chosen month. Committed capital and coins at work are different stories until the schedule finishes.
Yes. Every buy has an exchange fee and, on-chain, gas. Small weekly drips can leak more in fixed costs than a fewer larger buys. This sketch ignores fees so path effects stay visible; size fee drag separately before you automate.
No. DCA spreads entry timing; it does not guarantee profit, stop a bear market, or replace position sizing. If the asset trends down for the whole window, averaging still buys a depreciating bag — just at a different average than a single buy.
Treat shapes as stress stories, not forecasts. Rally-then-chop hurts DCA vs an early lump; bleed-then-recover often helps DCA; U-bottom and late spike show mid-window and back-loaded buys. Compare shapes with the same start, end, and budget.
