ProReckoner's Home & Life Admin calculators are built for households making real financial decisions — budgeting, moving, renovating, planning a family or comparing vehicle costs. Tools cover household budgeting and utilities (utility bills, 50/30/20 budgeting, subscription audits), moving and relocation (moving costs, cost-of-living comparison, bond/cleaning costs), home ownership and renovation (renovation ROI, paint quantity, energy efficiency payback), family and household planning (childcare, pet ownership, wedding budgets) and vehicle ownership (true cost of car ownership, car vs public transport). AU and US contexts throughout.
Household Budgeting & Utilities
3 toolsUtility Bill Cost Estimator
Total utility bill from usage, unit rate and daily supply charge. Free calculator for checking electricity, gas or water bills before they arrive, or comparing plans.
Total bill = (Usage × rate) + (Daily supply charge × billing days)
Most utility bills combine a usage-based charge with a fixed daily supply/connection charge — both need to be included for an accurate total.
Household Budget Planner
Split your monthly income into needs, wants and savings using the 50/30/20 rule. Free household budget planning calculator to check whether your spending is on track.
Needs = Income × 50%
Wants = Income × 30%
Savings/debt = Income × 20%
A widely used general budgeting guideline, not a strict rule — high cost-of-living areas or specific financial goals often call for a different split.
Subscription Cost Audit Calculator
Total monthly and annual cost of streaming, software and membership subscriptions in one place. Free subscription audit calculator to catch subscription creep.
Monthly total = Sum of all subscriptions
Annual total = Monthly total × 12
Small monthly amounts are easy to overlook individually — seeing the annualised total is often the number that actually prompts a review.
Moving & Relocation
3 toolsMoving Cost Estimator
Total moving cost from distance, truck/van size and labour hours. Free removalist cost estimator for planning a household move budget.
Truck cost = Distance × rate per km (by size)
Total = Truck cost + (Labour hours × rate) + Callout fee
Rates vary significantly by region and removalist — this gives a general planning estimate using typical rate bands, not a formal quote.
Cost-of-Living Comparison Calculator
Dollar and percentage difference in total monthly living costs between two locations. Free cost-of-living comparison calculator for relocation planning.
Difference = Location B costs − Location A costs
% difference = (Difference ÷ Location A costs) × 100
Include rent/mortgage, groceries, utilities, transport and any other recurring essentials in each total for a meaningful comparison.
Bond & Cleaning Cost Calculator
Expected bond refund after cleaning and repair costs are deducted. Free end-of-lease calculator for renters moving out.
Expected refund = Bond held − Cleaning cost − Repair/damage cost
This is a planning estimate only — the actual refund depends on the landlord/agent's inspection and any dispute process, not a calculation.
Home Ownership & Renovation
3 toolsHome Renovation ROI Calculator
Estimated return on investment for a kitchen, bathroom, landscaping or general renovation, using typical value-uplift benchmarks. Free calculator for homeowners weighing up a renovation.
Value added = Current home value × typical uplift % (by renovation type)
ROI % = (Value added − Renovation cost) ÷ Renovation cost × 100
Uplift percentages are general industry averages, not a valuation of your specific property — actual results vary significantly by location, market conditions and renovation quality.
Paint Quantity Calculator
Litres of paint needed for a room based on dimensions, number of coats and coverage rate. Free consumer paint quantity calculator for a DIY room repaint.
Wall area = 2 × (length + width) × height − (openings × 2m² each)
Litres needed = (Wall area × coats) ÷ coverage per litre
Coverage rate varies by paint type and wall texture — check the tin's stated coverage for the most accurate result.
Home Energy Efficiency Payback Calculator
Payback period in years for an energy efficiency upgrade — solar, insulation, heat pump or appliance — based on upgrade cost and estimated annual savings. Free calculator for weighing up a home energy upgrade.
Payback period (years) = Upgrade cost ÷ Estimated annual savings
A simple payback calculation — doesn't account for financing costs, rising energy prices, or equipment lifespan, which can shift the real-world figure in either direction.
Family & Household Planning
3 toolsChildcare Cost Calculator
Weekly and annual out-of-pocket childcare cost from the daily fee, days per week and your own confirmed subsidy rate. Free calculator for family budget planning.
Weekly fee = Daily fee × days per week
Out-of-pocket = Weekly fee × (1 − subsidy rate)
This calculator uses a subsidy rate you enter yourself — it does not calculate eligibility or the actual subsidy percentage, which depends on income, activity level and the specific government scheme in your country.
Pet Ownership Annual Cost Calculator
True annual cost of pet ownership from food, vet/insurance and other recurring expenses. Free calculator for budgeting before or after bringing home a pet.
Monthly total = Food + Vet/insurance + Other costs
Annual total = Monthly total × 12
Recurring monthly costs annualised — doesn't include one-off costs like initial adoption fees, desexing, or unexpected major vet expenses.
Wedding Budget Planner
Total wedding budget estimate from guest count, per-head catering cost, venue and other major expenses. Free wedding budget planning calculator.
Catering total = Guest count × per-head cost
Total budget = Catering total + Venue cost + Other costs
Catering scales directly with guest count, making it the most sensitive line item to trim if the budget needs to come down.
Vehicle Ownership
2 toolsTrue Cost of Car Ownership Calculator
True annual cost of car ownership — depreciation, insurance, maintenance and fuel combined — plus cost per kilometre. Free calculator for comparing vehicles or deciding whether to keep a car.
Depreciation = Purchase price × annual depreciation %
Fuel cost = (Annual km ÷ 100) × consumption (L/100km) × fuel price
Total annual = Depreciation + Insurance + Maintenance + Fuel
Depreciation is usually the single largest cost of car ownership, yet it's the one most owners never actually calculate since no bill arrives for it.
Car vs Public Transport Cost Comparison
Annual cost comparison between driving and public transport, showing potential savings from switching. Free calculator for weighing up commute options.
Public transport annual = Weekly PT cost × 52
Difference = Car annual cost − PT annual cost
For the fairest comparison, use the True Cost of Car Ownership Calculator's full output (including depreciation) as the car cost input, not just fuel.
