Shopping for a new one

Worth comparing a few current certified models before deciding.
Protecting what you have
A electric water heater like the Ruud PROUH50 T2 RU400-SO is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Electric Water Heater category page shows all 596 electric water heaters ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
