Variables, defaults, and limits
- Monthly debt
- Monthly debt is a number input. The displayed starter value is 1,800; it is an example, not a hidden assumption.
- Default: 1,800
- Accepted values: Minimum: 0. Numeric entries must be finite and unambiguous.
- Gross monthly income
- Gross monthly income is a number input. The displayed starter value is 6,000; it is an example, not a hidden assumption.
- Default: 6,000
- Accepted values: Minimum: 0.000000000001. Numeric entries must be finite and unambiguous.
Formula and calculation rule
R=100·x₁/x₂; x₁=Monthly debt; x₂=Gross monthly incomeDebt to income calculator evaluates the registered expression “R=100·x₁/x₂; x₁=Monthly debt; x₂=Gross monthly income” with the validated inputs. Full calculation precision is retained until the result is formatted for display.

Assumptions
- Debt to income calculator uses the visitor-entered values exactly as labelled; it does not retrieve private records or current rates.
- The calculation is limited to the declared relationship: R=100·x₁/x₂; x₁=Monthly debt; x₂=Gross monthly income.
- Intermediate values are not rounded; display rounding is applied only at the presentation boundary.
- The deterministic calculation runs locally and does not upload calculator inputs to the application API.
- All amounts use one currency. Rates, fees, taxes, timing, and contributions are user assumptions; the result is not financial, tax, investment, or lender advice.
Validation and boundaries
- Every visible required input must be present; a missing value is never replaced with zero.
- NaN, positive or negative infinity, unsafe overflow, and a non-finite final result are rejected.
- Field-specific minimums, maximums, and choices apply to Monthly debt, Gross monthly income.
- No current market rate, lender offer, jurisdictional tax rule, or guaranteed return is supplied or inferred.
Review and correction links
Common mistakes
- Confirm the meaning and unit of Monthly debt, Gross monthly income before calculating; a numerically valid value can still use the wrong convention.
- Do not round intermediate values when checking the result, because early rounding can change the last displayed digits.
- Changing an unstated real-world assumption does not change the calculator until the corresponding displayed input is changed.
- Do not treat an estimate as a quotation, approval decision, tax filing, accounting record, or guaranteed outcome.
