How it works
Boat and RV policies are seasonal products priced as if they were not: insurers will happily bill twelve months for a rig that floats or rolls seven. The legitimate saving is the lay-up structure - during storage months, collision and liability exposure collapse while comprehensive risks (fire, theft, hail at the storage lot) remain, so carriers discount those months commonly thirty to fifty percent. This calculator converts a year-round quote into its seasonal equivalent by weighting the discount across your unused months, then divides everything into a monthly set-aside so the annual renewal never ambushes the budget. The second half protects value rather than premium: actual-cash-value policies depreciate the payout every year - eight percent annually turns a $42,000 rig into roughly $27,600 of settlement after five - while agreed-value policies promise the scheduled figure at total loss, usually for a modest load on boats and classic rigs. Two cautions keep the discount honest: never let liability lapse entirely during lay-up, because a neighbour's child or a falling branch creates claims all winter; and notify the carrier before any off-season use, since a claim filed mid-lay-up without notification is the classic denial letter. Seasonal pricing rewards people who actually store their rig - not people who merely plan to.
Formula
seasonal premium = full premium x (1 - lay-up discount% x lay-up months / 12) | ACV payout = value x (1 - depreciation)^years | gap avoided = agreed value - ACV payout
Tips
- Keep comprehensive coverage alive through storage - fire, theft and hail do not respect the off-season.
- Never drop liability fully during lay-up; injuries and damage still happen around stored rigs.
- Tell the insurer before any off-season outing; an undisclosed use date voids exactly the discount you took.
- Agreed value costs more up front but fixes the total-loss number - decisive once depreciation compounds.
- Winterize to carrier spec: freeze damage claims are routinely denied when lay-up procedures were skipped.
Frequently asked questions
- Can I pause my boat or RV insurance in the off-season?
- You can restructure but should never fully pause: suspending everything leaves the storage lot's fire, theft and storm risk uninsured, plus any liability if someone wanders near the rig. The correct move is a lay-up endorsement keeping comprehensive and premises liability alive while dropping road-use cover at a discount.
- How much does lay-up storage save on premiums?
- Storage-month discounts commonly run 30% to 50% on the dropped coverages. On this calculator's defaults - $1,150 year-round with a 40% discount across five stored months - the seasonal structure saves about $192 a year, roughly one month's premium banked instead of burned.
- What is agreed value vs actual cash value on boat insurance?
- Agreed value pays the scheduled amount at total loss regardless of age; actual cash value pays replacement cost minus depreciation. At 8% annual depreciation, five years turn a $42,000 insured value into about $27,600 of ACV settlement - a $14,400 gap that agreed-value pricing exists to close.
- Does RV insurance cover while parked at a campsite?
- Yes - most policies extend liability and contents coverage while the RV is stationary and occupied, functioning like temporary homeowners coverage. What changes by state and policy is whether long-term stationary parking shifts the unit toward a home-policy treatment, which matters for full-time RVers who need specialized endorsements.
- Do I need separate insurance for a trailer?
- Liability while towing transfers from the tow vehicle's auto policy, but physical damage does not - a trailer struck while parked or stolen from a lot needs its own comprehensive coverage, usually inexpensive. Check whether your auto policy's trailer endorsement caps value below what yours is worth.
