Insurance Premium Comparison Calculator
Compare two insurance premiums over a horizon.
Compare two insurance premiums over a multi-year horizon to see cumulative costs, total out-of-pocket differences, and long-term savings gaps.
What this tool does
This calculator compares two insurance premium options across a multi-year period by computing their cumulative costs. Enter the monthly premium for each option and your comparison timeframe in years. The tool calculates the total out-of-pocket cost for each policy over that horizon and shows the difference between them. The result illustrates how seemingly small monthly variations can accumulate into substantial gaps over time. The comparison assumes consistent monthly premiums with no changes, adjustments, or additional fees factored in. This calculation is useful for evaluating competing insurance quotes or understanding cost divergence across different time periods. The output is for educational illustration of cost comparison and does not account for coverage differences, claim histories, or policy variations between options.
Quick answer: with the default values, the result is $1,800.00 (Option B Saves). Adjust the values below for your own figures.

60/month vs 45/month over 10 years: 7,200 vs 5,400 = 1,800 gap. Assuming coverage is equivalent, switching saves 1,800 over a decade. Coverage comparison (exclusions, limits) matters as much as headline premium.
A worked example
With the defaults: option a monthly of 60, option b monthly of 45, horizon of 10. The tool returns 1,800.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Option A Monthly, Option B Monthly, and Horizon. Two inputs usually tip the answer one way or the other. Flipping each value past a round threshold shows which input moves the result most.
The formula behind this
Monthly × 12 × years for each. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Reading a low result
A disappointing result is information, not a judgement. The input that dragged the figure down most is usually where a single change has the largest effect, since depth on the worst input tends to move the result more than spreading effort across every input at once.
What this doesn't capture
The result reflects only the inputs you provide and the assumptions built into the formula. It is a simplified model rather than a complete picture, and factors specific to your situation may matter just as much.
What to calculate alongside this
One figure by itself is fragile. The annual subscriptions audit calculator, the d and o insurance calculator, and the health insurance calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool.
Comparing £60 and £45 monthly premiums over 10 years results in a total difference of $1,800.00.

Sources & Methodology
Methodology
The calculator computes the total premium difference between two insurance options over a specified time horizon. It takes the monthly premium for each option, multiplies by 12 to annualise, then multiplies by the number of years to obtain the total cost for each option over the full period. The result shows the absolute difference between these two totals, expressing how much more or less one option costs compared to the other in cumulative terms. The model assumes premiums remain constant throughout the horizon and does not account for premium increases, policy changes, coverage adjustments, tax treatment, fees, or any non-premium costs associated with either option. It treats the comparison as a simple linear calculation and does not model inflation, investment returns, or changes in personal circumstances that might affect suitability.
