Live planning model
Compare two moves on one economic boundary
A low quote can still consume housing overlap, household time, and disruption exposure. Define those four components consistently for both plans, then inspect the signed component differences.
| Cost component | Scenario A | Scenario B | A minus B |
|---|
Current calculation process
Formula, default substitution, intermediate quantities, and check
T = direct + overlapDays x dailyHousing + personalHours x hourlyValue + disruptionProbability x disruptionImpact
Each scenario produces an economic decision total. The expected disruption line is probability multiplied by consequence; it is neither a fee nor a claim that the event will occur.
Five-step comparison
Make the alternatives genuinely comparable
- Write the service boundary for each scenario: inventory, packing, transport, storage, stairs, long carries, travel, and delivery timing.
- Enter direct cash costs from written estimates and add omitted cash items before comparison.
- Value housing overlap from the actual duplicate-rent, hotel, or temporary-housing plan.
- Estimate household hours and apply an explicit opportunity-cost rate rather than hiding time inside the quote.
- Define one disruption event, assign probability and consequence consistently, then retain the component ledger with supporting evidence.
Five comparison concepts
Why a quote is not the whole decision
Scope parity
A packing-inclusive quote cannot be compared fairly with a truck-only price until labor and materials are normalized.
Overlap is time-based
Duplicate housing grows by day, so a slower handoff can outweigh a cheaper transport line.
Time value is economic
Personal hours are not necessarily cash paid, but making them visible prevents “free” labor from biasing the result.
Expected loss is weighted
A 10% chance of a $2,000 disruption contributes $200 to the decision total, not $2,000 and not zero.
Signed differences diagnose
The A-minus-B column shows which component causes the final ranking instead of reporting only a winner.
Symbols and default substitution
Trace both totals
| Symbol | Meaning | Default A | Default B |
|---|---|---|---|
| D | Direct cash cost | $6,200 | $7,600 |
| h x c | Housing days x daily cost | 4 x $210 | 1 x $210 |
| t x v | Personal hours x hourly value | 18 x $35 | 7 x $35 |
| p x L | Disruption probability x impact | 15% x $1,800 | 6% x $1,800 |
| T | Risk-adjusted total | sum A | sum B |
Default substitution: A = 6,200 + 4 x 210 + 18 x 35 + 0.15 x 1,800. B = 7,600 + 1 x 210 + 7 x 35 + 0.06 x 1,800. The ledger exposes every term before ranking.
Three analytical lenses
Interrogate the ranking
Probability sensitivity
Rerun plausible low and high probabilities. If the preferred scenario flips, the decision depends on uncertain risk judgment.
Time-rate threshold
Change the hourly value to zero to see the cash-only ranking, then restore the rate to measure the price of convenience.
Contract boundary
If an accessorial service is uncertain, add it to the scenario that may incur it or model it as a defined disruption rather than ignoring it.
Two decision cases
Normal and boundary comparisons
Self-managed versus full service
A household compares a lower direct-cost plan requiring four overlap days and more personal work with a higher quote that shortens overlap. The component ledger shows whether convenience is worth the cash premium.
Zero-risk comparison
Setting both disruption probabilities to zero removes expected-loss weighting without altering direct, housing, or time costs. This isolates whether risk assumptions caused the result.
Terms
Scenario vocabulary
- Direct cost
- Cash expenditure assigned directly to the move plan.
- Housing overlap
- Days when old, new, or temporary housing costs coexist.
- Opportunity cost
- The explicit value assigned to household time consumed.
- Disruption event
- A clearly defined adverse occurrence, such as delayed delivery.
- Expected exposure
- Probability multiplied by the modeled economic impact.
- Scope parity
- Comparing alternatives with equivalent included work and assumptions.
Moving-scenario questions
Frequently asked questions
Is expected disruption cost an extra charge?
No. It is probability multiplied by economic impact so uncertain disruption can be included in a decision. It is not an invoice or forecast.
Should both scenarios use the same hourly value?
Usually yes when the same household time is being valued. Use different rates only when the people or opportunity costs genuinely differ and document why.
What belongs in direct move cost?
Include every cash item within the chosen scope: mover or truck, packing, fuel, tolls, lodging, storage, helpers, and known accessorial services.
How do I choose a disruption probability?
Define one event first, use available mover and route evidence, and test a plausible range. Do not present a subjective probability as measured fact.
Can I compare a binding and non-binding estimate?
You can, but first understand what each written estimate covers and model plausible adjustments or accessorial services explicitly.
What if the totals are almost equal?
Treat the result as sensitive. Review the component differences and choose on contract terms, reliability, flexibility, and preferences not represented by the dollar model.
Limits and evidence
Do not mistake an expected value for a bill
- The disruption line is a decision weight; real outcomes are usually zero loss or a larger realized loss.
- Probabilities are user judgments and can dominate close comparisons.
- The model does not price emotional stress, service quality, legal liability, or insurance coverage.
- Direct cost accuracy depends on written scope, inventory, accessorial services, and binding status.
Evidence record: keep both written estimates, inventories, emails defining included services, overlap calendar, time assumptions, disruption definition, and exported scenario report. This is planning analysis, not legal, insurance, or financial advice.
