Frequently asked questions
What does the calculation include?
Percentage change = (new premium − previous premium) ÷ previous premium. The prefilled example is 840 − 800 = +40, or +5%. A zero previous premium has no defined percentage change, though the amount difference remains available. Compare the same policy, billing period, and currency; the tool does not compare coverage, deductibles, or policy terms.
Which values should I enter?
Compare premiums for the same period and show the amount and percentage change. Use consistent amounts, units, and time periods.
Is the result definitive?
No. Check the assumptions and rules that apply to your situation; this is an illustrative calculation, not professional advice.
