How we calculate
We use standard industry formulas and well-established calculation methods. For mortgages, we use the amortization formula. For energy costs, we use wattage and utility rates. All assumptions are transparent—you control every input. Our goal is to help you make informed decisions, not to predict the future (interest rates change, prices fluctuate, situations vary). Always verify our estimates with official quotes before making major decisions.
