Distance symmetry is not time symmetry
Connections, border procedures, and local transfers can give similar distances very different durations.
Practical relationship planning
Compare two meeting locations using each person’s travel cash and hours, shared destination cost, a time value, and an explicit fairness-gap weight.
MEETING LOCATION BALANCE
The cheapest location overall can place most of the travel burden on one person. This calculator builds a cash-time burden for each traveler at two destinations, measures the gap between them, and applies an explicit fairness weight before recommending the lower score. The fairness weight is a chosen decision rule, not a moral judgment.
MEETING LOCATION BALANCE
A higher fairness weight makes unequal personal burden more consequential in the score. Review each person’s raw cash and hours before accepting the recommendation.

CURRENT CALCULATION PROCESS
Bij=Cij+hTij; Δj=|BAj−BBj|; Sj=CAj+CBj+Lj+h(TAj+TBj)+fΔj
For each location, combine each traveler’s own cash and valued time, measure their absolute burden gap, then add total cash, total time value, and the weighted gap to the location score.
| Symbol | Meaning | Unit | Default |
|---|---|---|---|
| j | Location index | A or B | two locations |
| Cij | Traveler i cash at location j | USD | entered |
| Tij | Traveler i travel time | hours | entered |
| Lj | Shared destination cost | USD | 240; 190 |
| h | Planning value of time | USD/hour | 20 |
| Bij | Individual cash-time burden | USD-equivalent | calculated |
| Δj | Personal burden gap | USD-equivalent | calculated |
| f | Fairness-gap weight | decimal | 0.50 |
| Sj | Location comparison score | USD-equivalent | calculated |
Conversions and rounding: Convert fairness percent to decimal. Shared destination cost enters once, while each traveler’s cash and time enter separately. Preserve full precision and display scores to cents.

SUBJECT FUNDAMENTALS
MODEL AND FORMULA
For each location, combine each traveler’s own cash and valued time, measure their absolute burden gap, then add total cash, total time value, and the weighted gap to the location score.
DEEPER DECISION ANALYSIS
Connections, border procedures, and local transfers can give similar distances very different durations.
A location can be inexpensive overall while asking one person to bear most of the travel.
Test zero, moderate, and full gap weights, then discuss what the numbers omit.
WORKED DECISION CASES
The default Location B has a smaller personal burden gap and a lower full score.
A lower fairness weight can represent an explicit one-trip agreement, provided it is freely chosen and revisited.
TECHNICAL LANGUAGE
EVIDENCE AND DATA LINEAGE
Save dated transport quotes, door-to-door itinerary estimates, local lodging or activity quotes, refund terms, and the agreed time and fairness weights. Use matching dates and booking conditions where possible.

FREQUENTLY ASKED QUESTIONS
It is a destination expense for the meeting rather than one separate charge per traveler.
It compares only total cash and valued time while still reporting the raw burden gaps.
It adds the entire individual burden gap to each location score.
This model uses one common weight for transparency; discuss separate constraints outside the score.
Yes. That sensitivity is useful evidence that the decision depends on the fairness rule.
No. This page compares two destinations and individual burden; Visit Comparison compares two itineraries across repeated visits.
IMPORTANT NOTE
A destination must remain acceptable to both people after current safety, entry, accessibility, health, and consent checks. Do not use the score to pressure travel.
