Why publish the model
Most Alaska cost numbers online are either a $99-per-day blog from 2018 or an influencer's flex post. Neither tells you what your trip will actually cost. We publish the full model so you can check our work, adjust it to your situation, and cite it. Every figure below feeds the interactive calculator directly — change a number here and the calculator changes with it.
Transportation
Per-day vehicle cost plus fuel. Fuel is computed from trip mileage, vehicle MPG, and a gas price of $4/gallon.
| Vehicle | Cost per day | Assumed MPG |
|---|---|---|
| Rental car | $90 – $140 | 22 |
| Rental SUV / 4WD | $130 – $200 | 18 |
| RV (Class C) | $300 – $500 | 10 |
| Own vehicle (fuel only) | — | 22 |
| Trip length | Assumed driving miles |
|---|---|
| 5 days | 600 mi |
| 7 days | 900 mi |
| 10 days | 1,300 mi |
| 14 days | 1,800 mi |
| 21 days | 2,400 mi |
Lodging
Per-night rate by style, charged for trip length minus one night. RV mode overrides this with an RV-park rate of $40 – $80/night. Party size and season then scale the lodging line (see multipliers below).
| Lodging style | Per night |
|---|---|
| Budget | $90 – $140 |
| Mid-range | $200 – $300 |
| Premium | $400 – $700 |
Food
Per person, per day. Travel style follows the lodging tier you pick.
| Style | Per person / day |
|---|---|
| Budget | $40 – $60 |
| Mid-range | $70 – $100 |
| Premium | $120 – $180 |
Activities
Per person, added only for the activities you select. These are the line most under your control.
| Activity | Per person |
|---|---|
| Flightseeing (Talkeetna) | $400 – $700 |
| Halibut charter (Homer) | $300 – $450 |
| Glacier day cruise (Kenai Fjords) | $200 – $300 |
| Northern lights tour | $100 – $200 |
| Denali bus / Tundra tour | $50 – $170 |
Multipliers
Party size sets a head count (for per-person and food math) and a lodging multiplier. Season scales lodging to reflect off-peak discounts.
| Party | Head count | Lodging × |
|---|---|---|
| Solo | 1 | ×1.00 |
| Couple | 2 | ×1.00 |
| Family of 3–4 | 3.5 | ×1.20 |
| Group of 5–6 | 5.5 | ×1.70 |
| 7+ travelers | 8 | ×2.20 |
| Month | Lodging × |
|---|---|
| Late May | ×0.85 |
| June | ×0.95 |
| July | ×1.00 |
| August | ×1.00 |
| September | ×0.85 |
Miscellaneous & the cruise anchor
A flat $50 – $150 plus $15 – $30 per person covers park fees, gear, and incidentals. For comparison, the model anchors against a typical 7–10 day Alaska cruise at $4,500 – $6,500 per person.
What the model can't see
- The flight to Alaska. Excluded on purpose — origin matters too much for an honest generic number.
- Rental shortages and lodge surge pricing on specific dates. Booking inside 60 days of a summer trip? Add a 15% buffer to transportation.
- Premium guided lodges ($1,000–2,500 per person, per night). No preset touches that tier.
- Weather-cancelled tours. Most refund cleanly; build a buffer day if one activity is the reason for the trip.
Questions about the methodology
- Where do these numbers come from?
- They are based on real Alaska bookings from trips we plan, last refreshed in May 2026. Rental rates and lodge prices are the two most volatile inputs and are re-checked against spring booking data each year; the rest holds steady year-to-year.
- Does the model include flights to Alaska?
- No. The flight-in varies too much by origin for a generic estimate to be honest. Plan $350–$900 per person from the lower 48 in 2026, on top of the calculator total.
- How is the per-person number derived?
- The total of all five categories is divided by a head count for the selected party size (a family of 3–4 is modeled as 3.5 heads, a group of 5–6 as 5.5, and so on), then divided by trip length for a per-person-per-day figure.
