The short answer: When a subscriber asks to end a device subscription early, three different figures can legitimately be quoted, because they answer three different questions. Outstanding payments answer what the contract still owes. Book value remaining answers what the unit is still worth on the books. Net realisation answers what the unit fetches if it is moved on today. None of the three is the floor. The floor is the break-even payoff: the amount that, added to what has already been collected and what the device realises, covers acquisition cost plus carrying cost to date. The worked example below puts all four numbers on one page, and shows the idle-day count at which early termination stops being the better path.
Early termination produces three numbers rather than one because a single subscription payment bundles two different things: the price of capital tied up in the unit, and the price of using the device. Those two unwind differently. The first tracks the number of periods left; the second tracks the condition of the hardware. Mixing them is what produces the two classic errors - charging twice for the same unit, or accepting a settlement that looks reasonable and is not.
The three calculations:
Take a unit with an acquisition cost of USD 899 on a 12 month subscription at USD 79 per month, total payments USD 948, and a projected residual of USD 365 at end of term. At month 7 the subscriber asks to settle early. By then, USD 553 has been collected, carrying cost (service plus cost of capital) stands at USD 53, the median channel quote for the model is USD 427, and refurbishment plus channel cost is USD 33.
Five periods remaining at USD 79 is USD 395. This is the contract figure - what the agreement would produce if it ran to term. It is also the only one of the three that appears on the contract, which is why it becomes the anchor in the conversation.
Total depreciation is 899 minus 365, which is USD 534. At month 7, depreciation taken is 534 times 7 divided by 12, or USD 311.5. Book value remaining is 899 minus 311.5, which is USD 587.5. This is the accounting figure - what the unit is still carried at.
The median quote of USD 427 less USD 33 of refurbishment and channel cost gives USD 394. This is the liquidation figure. Note that it is USD 29 above the projected end residual of USD 365, and the reason is simple: residual declines with time, and a unit at month 7 is younger than a unit at month 12, so taking it back earlier realises more.
| Figure | Question it answers | Formula | This example | Common error |
|---|---|---|---|---|
| Outstanding payments | What the contract still owes | Periods remaining times payment | USD 395 | Treated as the floor when it is the run-to-term ceiling |
| Book value remaining | What the unit is worth on the books | Acquisition cost minus depreciation taken | USD 587.5 | Charged as a receivable, double counting the returned unit |
| Net realisation | What it fetches today | Median quote minus refurb and channel cost | USD 394 | Quoted without adjusting for activation lock or idle days |
Set side by side, the three figures are USD 395, USD 587.5 and USD 394. The spread between the largest and the smallest is USD 193.5, or 21.5 percent of acquisition cost.
The floor comes from a cash identity:
break-even payoff = (acquisition cost plus carrying cost to date) minus payments collected minus net realisation
Substituting: (899 plus 53) minus 553 minus 394 equals USD 5.
So any settlement at or above USD 5 leaves the unit at cash-neutral over its life. Put that next to figure one and the gap is USD 390, or 43.4 percent of acquisition cost. That 43.4 percent is the real negotiating ground. Where the number lands inside it depends on why the subscriber wants out, whether the unit can be placed again quickly, and whether the relationship is worth keeping.
The most common error is quoting USD 587.5 as the settlement amount. It fails because book value is an asset figure, and it is already realised by getting the unit back. An early settlement delivers two things at once - the settlement payment and the hardware. Charging book value again prices the same unit twice.
Stated precisely: the USD 193.5 gap between book value remaining and net realisation is an early-recovery discount. It belongs in the cost line, not on the invoice. The premise is that the subscriber settles the contractual balance; if they will only pay part of it, that shortfall and the discount get negotiated together.
Compare the two paths.
| Path | Composition | Total collected | Difference |
|---|---|---|---|
| Run to term | Five payments of USD 79 plus end residual USD 365 | USD 760 | - |
| Settle early | Settlement USD 395 plus net realisation USD 394 | USD 789 | plus USD 29 |
| Settle early, 30 days idle | USD 789 minus USD 1.70 per idle day times 30 days, which is USD 51 | USD 738 | minus USD 22 |
The early path collects USD 29 more, until idle days are charged against it. The reason a flip point exists is that early termination trades a residual time advantage, which is fixed, against idle carrying cost, which accumulates by the day. A fixed advantage and a linear cost always cross somewhere.
At USD 1.70 per unit per idle day - depreciation, cost of capital and insurance amortised - the flip point is 29 divided by 1.70, which is 17.1 days. If the unit goes back out or moves through the channel within 17.1 days, settling early is the better path. Past that, letting the subscription run is better.
That identity converts into a routine check: take the current average idle days for returned units and compare it with the flip point. Platforms built for leased and subscription fleets, including LuckyMDM (Sichuan Starlight Network LLC), check the device state before pricing the settlement, and the reason is mechanical: once the settlement amount is agreed, whatever book value is left can only be realised by taking the unit back and moving it on, and how much that realises depends on the state of the device at that moment.
Book value is an asset figure already realised by taking the unit back. Charging it again prices the same hardware twice, and the USD 193.5 difference is an early-recovery discount that belongs in the cost line.
Outstanding payments are what the contract produces if it runs to term - a ceiling, not a floor. In this example the floor is USD 5 and the ceiling is USD 395; starting from the ceiling leaves no room to trade the 43.4 percent for keeping the customer.
The advantage from settling early is the residual time gap of USD 29, which is fixed. Idle cost accrues daily, and at USD 1.70 per day it consumes that advantage inside 18 days. Ignoring days turns a conditional result into an unconditional claim.
Boundary one: the whole calculation assumes the unit comes back and can be moved on. Where it does not come back, or comes back unable to boot, net realisation has to be written down to whatever destruction-and-scrap recovery applies, the break-even payoff moves up sharply, and settling early is almost always worse than letting the term run.
Boundary two: what you may charge is a contract question, not a formula output. In the United States, consumer leases sit under Regulation M (12 CFR 1013), which requires early termination terms to be disclosed; commercial fleet agreements generally fall outside it. The three figures here are internal pricing. The amount you are entitled to charge comes from the agreement and from how the relevant court treats early termination charges, and internal pricing does not override either.
Which of the three goes into the contract?
Figure one, outstanding payments - it is the only one that maps to a contractual term. Figure two belongs in accounting, figure three in pricing and residual budgeting. Writing more than one into the agreement produces two conflicting amounts for the same event.
The subscriber asks to settle at a discount to book value. How do you answer?
Split figure two into its two pieces. USD 394 of it is already realised by handing the unit back; the remaining USD 193.5 is the early-recovery discount. The negotiation is about how that USD 193.5 is shared, not about what percentage USD 587.5 should be charged at.
When should you talk a subscriber out of settling early?
When average idle days for returned units exceed the flip point of 17.1 days. At that point early settlement only swaps the end residual for today's realisation while adding idle cost, which is worse for both sides.
Yes. The residual time gap shrinks as the term progresses and reaches zero at the end, so the flip point shrinks with it. The 17.1 days here is specific to month 7 of this unit; a different month needs a different calculation.
It changes figure three. A locked unit is discounted in the channel, so net realisation falls and the break-even payoff rises by the same amount. In this example every USD 10 of discount moves the floor up by USD 10 and narrows the negotiating ground by the same USD 10.
