Estimate calories burned while hiking from body weight, hiking time, trail effort, and pack weight using a simple MET-based model.
Add the weight of your water, gear, and food to estimate the total load in your hiking pack. The estimate assumes water weight equals its volume in liters multiplied by the entered kilograms-per-liter value.
Estimate hiking time from trail distance, average moving speed, elevation gain, and planned rest time. This simple planning model adds a pace-based travel estimate to an elevation adjustment and your break time.
Estimate total trail distance by multiplying the number of trail segments by the distance of each segment, measured in miles.
Estimate a hotel's room cost from the nightly rate, number of nights, rooms, and a simple lodging tax rate. This estimate excludes separately charged fees and extras.
Estimate the cents-per-point value of a hotel points redemption by comparing the cash room price after taxes with the points required and any cash copay. The estimate excludes taxes or fees not included in the cash price you enter.
Estimate the usable time between scheduled arrival and departure after subtracting your planned connection tasks and a personal buffer. This simple estimate does not check airport rules, flight schedules, or whether a connection is feasible.
Convert a measured map distance into the corresponding ground distance using the map scale ratio. Enter the map measurement and the scale denominator, then choose units for each distance.
Estimate a mileage reimbursement amount by multiplying eligible work miles by the per-mile rate you enter. This simple estimate does not determine which trips qualify or what rate an employer or tax authority permits.
Convert a distance in miles to its equivalent in kilometers using the standard conversion factor of 1.609344 kilometers per mile.
Estimate a local move's service cost from your own hourly crew rate, labor hours, travel fee, and packing-material budget. The estimate excludes costs you do not enter.
Add the distances of up to four consecutive trip legs to estimate your total route distance in kilometers.
Estimate the listed rental budget for outdoor gear by multiplying rental days by the daily gear cost and adding the cost of individually priced items. Enter amounts in your chosen currency. The estimate excludes any charges not entered.
Estimate a monthly rent budget from take-home income, other monthly housing costs, and the share of income you choose to allocate to housing. This is a planning estimate, not a lease or financial recommendation.
Estimate a rental car trip total from the daily rental rate, rental days, estimated distance, fuel efficiency, fuel price, and additional trip charges. The estimate adds rental charges, estimated fuel cost, and the extra charges you enter.
Estimate each diner's share of a restaurant bill by splitting the pre-tax food and drink total evenly, then adding each diner's equal share of tax and tip.
Estimate each diner’s share of a restaurant tip from the bill amount, selected tip rate, and number of diners. This result is the tip per person only.
Estimate the value of redeemed travel points in cents per point by comparing a cash trip total with the fees due on an award booking. Assumes both prices cover the same itinerary, travelers, and booking conditions.
Estimate a road trip budget by combining fuel, lodging, and meal costs. Enter your planned distance, vehicle fuel efficiency, fuel price, lodging nights and nightly rate, and meal budget per travel day. This estimate covers only those categories and does not include tolls, parking, activities, maintenance, or other trip expenses.
Find the pre-tax price and sales tax included in a tax-inclusive total using the total amount and tax rate you enter.
Estimate the combined weight of souvenirs and other packed luggage using the number of items and their average weight.
Estimate a taxi fare from a rider-entered starting charge, distance rate, trip distance, time rate, and metered trip time. The estimate uses the supplied tariff assumptions and excludes any unentered extras.
Estimate toll charges for a planned trip by adding the toll cost per one-way leg and multiplying by the number of legs and trips. Enter toll amounts in one currency.
Estimate a trip insurance planning amount by applying an assumed base rate to trip cost, then adjusting it for trip length, traveler count, and a user-selected coverage factor. This worksheet is an illustrative estimate, not an insurer quote.
Estimate the combined cost of planned itinerary activities and participant-based charges. Enter the number of activities, the average cost per activity, the number of participants, and the average cost per participant.
