What this calculator shows
Ratio-based finance decisions usually turn on how large one number is relative to another, not on either number by itself.
It is useful for measuring how much income is being drained by interest expense when one clean percentage is easier to judge than two disconnected amounts.
How to use it
- 1. Add the amounts that make up annual interest paid.
- 2. Add the amounts that make up annual gross income.
- 3. Review the interest cost ratio and the difference between the two amounts.
Formula and assumptions
Ratio percentage equals numerator divided by denominator, multiplied by 100.
The difference view is denominator minus numerator when both numbers are on the same basis.
Notes
A ratio can be directionally useful even when the underlying amounts are estimates, but the result is only as good as the inputs.
Worked example
A clean percentage is often easier to benchmark than two raw values sitting side by side.
This example uses the default sample inputs loaded on reset. It does not update with the live calculator entries above.

FAQ
FAQ
Why is the denominator so important?
Because the same numerator can look safe or stretched depending on the scale of the denominator.
FAQ
Can I use estimates?
Yes. Ratios are often used for planning, but the output will only be as reliable as the numbers entered.
