Lifetime cost comparison
Compare two choices using the same ownership horizon and the recurring costs that headline purchase prices usually hide.
Independent tool: calculations run locally in your browser; tracked commercial links remain separately disclosed when present.
Use the same horizon
Keep both options in one currency and use the same ownership period. The model adds purchase amount, recurring supplies, monthly utility amount and yearly upkeep across that horizon.
It does not model financing, inflation, resale value, repair probability, warranty claims, time value of money or changing tariffs.
Cost is only one decision factor.
A compatibility, safety or capacity requirement can override the lower modeled total. Treat the result as one input to a broader purchase decision.
