Thirteen weekly purchases can buy the same 2.905 LTC and leave either 2.840 or 2.890 LTC in your own wallet. In our fictional calendar, the difference is a fixed charge paid thirteen times rather than three. The purchases, execution prices and total cash contribution are identical.
A balance-triggered schedule adds another wrinkle. It can finish with fewer fees and a small amount still on the platform. Calling that entire difference a saving, or quietly assuming the remainder moves for free, gives the wrong answer. The withdrawal calendar needs its own ledger.
Original calculation, checked 26 October 2026. Every price, fee, minimum and threshold below is invented. We use dates in the 2027 calendar to fix weekdays and month-ends, not to forecast prices. No provider account was opened, funded or tested. The downloadable model compares 27 declared scenarios using the same purchases.
Hold the purchases fixed before comparing withdrawals
The account spends $20 each Monday from 4 January through 29 March: thirteen purchases, $260 altogether. The invented execution prices are $80, $100, $64, $80, $125, $100, $80, $64, $100, $125, $80, $100 and $125 per LTC. They acquire 2.90500000 LTC before withdrawal charges.
Funding and trading costs are zero in this exercise. That isolates what happens after the buys; it does not suggest real purchases have no other costs. Acquisitions round down to a whole litoshi, with unused cash recorded separately. These particular prices divide exactly, so the cash remainder is zero.
The purchase rule is the same kind of equal-cash schedule described in Investor.gov’s explanation of dollar-cost averaging. We are changing the transfer rule, not comparing averaging with a lump-sum investment. Our recurring-purchase guide covers the separate acquisition-cost question.
Three rules, including a charged final sweep
Each permitted withdrawal debits the entire available balance and deducts a fictional 0.005 LTC charge. The first comparison uses a 0.1 LTC minimum measured against that gross debit. All purchased coins are immediately available; there are no holds, processing waits or confirmation delays.
- Weekly: attempt a withdrawal after every purchase.
- Calendar month-end: attempt one on 31 January, 28 February and 31 March.
- 0.8 LTC threshold: after each purchase, withdraw if the available balance has reached 0.8 LTC.
The measured window ends at 00:00 on 1 April, after 87 days. In the following table, every rule also attempts to sweep any remainder at that endpoint. A successful sweep pays the same fee and must pass the same minimum. Empty attempts pay nothing.
| Withdrawal rule | Successful withdrawals | Total charges · LTC | Wallet receipt · LTC | Final platform balance · LTC |
|---|---|---|---|---|
| After each weekly purchase | 13 | 0.06500000 | 2.84000000 | 0.00000000 |
| Calendar month-end | 3 | 0.01500000 | 2.89000000 | 0.00000000 |
| 0.8 LTC threshold + final sweep | 4 | 0.02000000 | 2.88500000 | 0.00000000 |
The month-end rule retains 0.05 LTC more than the weekly rule because it incurs ten fewer charges. No buying-price advantage is involved. At the declared endpoint mark of $125, those coins have a quoted value of $6.25; the model has not sold them or obtained a bank payout.
The threshold rule makes three ordinary withdrawals, then a fourth to collect its tail. Omitting that last charge would make its comparison look better than its completed wallet receipt justifies.
Measure how much stays with the custodian, and for how long
Fees are only one column. We also add the platform’s balance after each day’s modeled events. One LTC held for seven days contributes seven custodial LTC-days; half an LTC held for fourteen days contributes the same total. Dividing by the 87-day window gives the mean amount held there.
| Rule with final sweep | Custodial LTC-days | Peak credited balance before withdrawal · LTC |
|---|---|---|
| Weekly | 0.0000 | 0.31250000 |
| Calendar month-end | 45.5575 | 1.01250000 |
| 0.8 LTC threshold | 26.8175 | 1.01250000 |
The zero in the weekly row is a property of this time grid. Each purchase is credited to the service and withdrawn at the same modeled instant. The peak column still records a positive balance. Real trading, withdrawal processing and network waits would add time that we have deliberately assumed away.
The month-end total can be checked by weighting each purchase by its days until transfer. January contributes 16.3125 LTC-days, February 13.445 and March 15.8. The threshold rule transfers earlier in these particular months and has a lower total, even though its largest credited balance is the same.
These figures are not loss probabilities, a custodian rating or the blockchain measure called coin-days destroyed. Equal LTC-days at two services need not mean equal risk. Self-custody also introduces key, backup and operational responsibilities. The SEC staff’s custody bulletin explains those different responsibilities; our arithmetic cannot choose between them for a reader.
The last 0.16 LTC changes the comparison
The threshold withdrawals occur on 25 January, 22 February and 22 March. Their gross debits are 1.0125, 0.9225 and 0.81 LTC. After three charges, the wallet has received 2.73 LTC. The last purchase, on 29 March, adds 0.16 LTC that does not reach the 0.8 LTC trigger.
Without a final sweep, the result is 2.73 LTC in the wallet plus 0.16 LTC on the platform: 2.89 LTC retained altogether. Those retained coins equal the month-end rule’s total, but their locations differ. A 1 April sweep delivers another 0.155 LTC after its charge, raising the wallet receipt to 2.885 LTC and reducing total retained coins by 0.005.
Now change the invented minimum to 0.2 LTC. The same 0.16 LTC tail fails either the gross or net definition. The requested final sweep is recorded as blocked; the model does not waive the rule, buy extra coins or pretend that the tail has vanished. Extending the horizon could change the outcome, but that would be a different calculation.
A different minimum can alter the whole schedule
A minimum measured after the fee is stricter than the same number measured before it. Yet its effect across repeated purchases can be surprising. Under a 0.2 LTC gross minimum, a 0.2 LTC purchase can leave immediately and deliver 0.195 LTC. Under a 0.2 LTC recipient minimum, it must wait and join a later purchase.
| Minimum basis | Successful withdrawals | Charges · LTC | Wallet receipt · LTC | Platform tail · LTC | Retained total · LTC |
|---|---|---|---|---|---|
| Gross debit | 10 | 0.05000000 | 2.69500000 | 0.16000000 | 2.85500000 |
| Recipient after fee | 9 | 0.04500000 | 2.86000000 | 0.00000000 | 2.86000000 |
The stricter definition happens to combine the final purchase with an earlier balance and clears the tail. It also causes more waiting: 5.32 custodial LTC-days, compared with 2.72 under the gross definition. This is not a general advantage of a stricter minimum; it follows from this purchase sequence and endpoint.
The wallet difference is 0.165 LTC. Only 0.005 LTC is a difference in total retained coins; the other 0.16 LTC is still on the platform in the gross-minimum case. Keeping those two effects separate prevents a location difference from being reported as investment performance. The small-purchase guide covers the underlying minimum and split-withdrawal checks.
State which amount your fee percentage uses
A 0.005 LTC fee on a 0.5 LTC gross debit is 1% of the debit. The recipient gets 0.495 LTC, so the same fee is about 1.0101% of the received amount. Both calculations are valid; they answer different questions.
For a fixed fee f, keeping fee / gross debit at or below a chosen fraction r requires a debit of at least f / r. Using fee / recipient amount instead requires at least f × (1 + 1/r). With the invented 0.005 LTC fee and a chosen 1% ratio, those thresholds are 0.5 and 0.505 LTC respectively.
A fee-ratio target supplies neither a safe custody period nor a suitable investment amount. The package also varies the fixed charge to zero, 0.001 and 0.01 LTC. Those cases show how sensitive the fee column is to its assumption; they do not estimate future provider prices.
Use the service’s actual preview before applying a rule
Real charges need not be fixed. Kraken’s withdrawal documentation says minimums and fees apply and that the final charge can differ from its public table. Coinbase’s disclosure distinguishes its estimated sending charge from the network fee it ultimately pays, including batching effects. Our “withdrawal charge” is therefore an invented service deduction, not a measured Litecoin miner fee.
Check the asset and supported network, gross debit, deduction, recipient amount, minimum basis and balance available now. Withdrawal holds can affect availability even when trading remains possible. A calendar reminder cannot bypass an account restriction.
Keep the purchase schedule and withdrawal rule as separate records. Include what happens if purchases stop, a quote changes or the final amount cannot leave. Our purchase-cost comparison helps examine one route’s entered charges and minimums; the downloadable calendar handles the repeated-event question. Keep actual transfers and residual balances in your portfolio records.
Reproduce the calendar and see its limits
Download the complete package, summary CSV, daily ledger or event ledger. The method fixes event order, minimum definitions and the endpoint. Inputs include every price and policy; a blank checklist helps record a real quote privately.
The standard-library Decimal calculation reproduces 27 scenarios, 2,349 daily states and 540 purchase or withdrawal events. A separate Fraction-based verifier reconstructs their arithmetic and calendar triggers, checks daily conservation and tests boundary cases. It uses no network or historical price feed. Checksums identify the released files.
We exclude funding and trading costs, spread, slippage, taxes, interest, holds, failed services, processing waits and later spending from the receiving wallet. Different withdrawal groups can also create different future input and fee requirements, which are not priced here. The fixed-fee calendar establishes consequences of declared assumptions, not an optimal withdrawal policy. Source review and drafting used AI assistance; no independent external review or actual withdrawal is claimed.
