1. Formulas and units

Annual cost difference
nearMinusFarAnnualCost = nearAnnualTotalCost − farAnnualTotalCost

Where

nearMinusFarAnnualCost
Near minus far annual cost (currency units/year)Source: Calculated output
nearAnnualTotalCost
Near option annual total (currency units/year)Source: Calculated output
farAnnualTotalCost
Far option annual total (currency units/year)Source: Calculated output
Near annual total
nearAnnualTotalCost = nearMonthlyRent × 12 + nearWeeklyCommuteDirectCost × commuteWeeksPerYear + nearWeeklyCommuteHours × commuteWeeksPerYear × hourlyTimeValue

Where

commuteWeeksPerYear
Commute weeks per year (weeks/year)Source: User assumption
hourlyTimeValue
Value of time per hour (currency units/hour)Source: User assumption
nearMonthlyRent
Near option monthly rent (currency units/month)Source: User assumption
nearWeeklyCommuteDirectCost
Near option weekly commute cost (currency units/week)Source: User assumption
nearWeeklyCommuteHours
Near option weekly commute hours (hours/week)Source: User assumption
nearAnnualTotalCost
Near option annual total (currency units/year)Source: Calculated output
Far annual total
farAnnualTotalCost = farMonthlyRent × 12 + farWeeklyCommuteDirectCost × commuteWeeksPerYear + farWeeklyCommuteHours × commuteWeeksPerYear × hourlyTimeValue

Where

commuteWeeksPerYear
Commute weeks per year (weeks/year)Source: User assumption
hourlyTimeValue
Value of time per hour (currency units/hour)Source: User assumption
farMonthlyRent
Far option monthly rent (currency units/month)Source: User assumption
farWeeklyCommuteDirectCost
Far option weekly commute cost (currency units/week)Source: User assumption
farWeeklyCommuteHours
Far option weekly commute hours (hours/week)Source: User assumption
farAnnualTotalCost
Far option annual total (currency units/year)Source: Calculated output
Annual rent premium
annualNearRentPremium = 12 × (nearMonthlyRent − farMonthlyRent)

Where

nearMonthlyRent
Near option monthly rent (currency units/month)Source: User assumption
farMonthlyRent
Far option monthly rent (currency units/month)Source: User assumption
annualNearRentPremium
Annual near rent premium (currency units/year)Source: Calculated output
Commute costs avoided
annualCommuteCostsAvoided = far annual commute direct and time cost − near annual commute direct and time cost

Where

annualCommuteCostsAvoided
Annual commute costs avoided (currency units/year)Source: Calculated output
Break-even near rent
breakEvenNearMonthlyRent = farMonthlyRent + annualCommuteCostsAvoided ÷ 12

Where

farMonthlyRent
Far option monthly rent (currency units/month)Source: User assumption
annualCommuteCostsAvoided
Annual commute costs avoided (currency units/year)Source: Calculated output
breakEvenNearMonthlyRent
Break-even near monthly rent (currency units/month)Source: Calculated output

Money inputs and outputs use the currency selected in the scenario without changing the canonical methodology. Pay, time, benefits and work-related costs use the units stated beside each input.

2. Worked example

Input assumptions

Compare 2,400 monthly rent near work with 1,800 farther away and a much larger weekly commute.

Calculation and outputs

Example

Compare 2,400 monthly rent near work with 1,800 farther away and a much larger weekly commute.

Near minus far annual cost
-6,000.00 currency units
Near option annual total
30,960.00 currency units
Far option annual total
36,960.00 currency units
Annual near rent premium
7,200.00 currency units
Annual commute costs avoided
13,200.00 currency units
Break-even near monthly rent
2,900.00 currency units

Rent premium, commute costs avoided and both annual totals remain visible.

Interpretation

Compare cash rent and commute spending separately from the entered value of time.

3. Validation and boundary checks

  • Commute weeks stay between 1 and 53.
  • Rent, commute cost and time value are non-negative.
  • Both options use the same commute weeks and time value.

4. Assumptions and source classification

  • Rent stays constant for the annual comparison.
  • The same hourly time value applies to both commutes.
  • Only entered direct commute costs are included.

This calculator has no current policy-data dependency. Its work and pay assumptions are user supplied. Registered family-level regression suites exercise the shared work-logic engine and worked-result reconciliation.

5. Limitations

  • No local rent, transport, tax or cost-of-living dataset is applied.
  • Moving costs and housing quality are excluded.
  • Time value is subjective and not cash spending.

This is educational decision support, not personalised tax, legal, financial or career advice. Check the treatment of your circumstances under the rules that apply to you and seek qualified advice where appropriate.

6. Update and evidence policy

Registered family-level suites test formula invariants and example reconciliation; the release ledger records that coverage without claiming a separate oracle for every line of public copy. There is no official threshold or benchmark to refresh for this calculator. Work and pay inputs remain user-supplied because they vary by person, job and contract.
