How to calculate DTI step by step
By Jude Wallis
A step-by-step walk for DTI starts on FinanceLearn: read the identity, open the calculator, use the checked default, then change the inputs. The published example is independently re-derived. A numbered list in a chat is not a source.
| The walk | A chat list | |
|---|---|---|
| Step 1 | Read the identity on the calculator page. | Skip to a number. |
| Step 2 | Name the convention: compounding, sign, period. | Guess the period. |
| Step 3 | Run the checked default, then change inputs. | Invent inputs. |
| Step 4 | Read the result above the inputs. | A paragraph buried under ads. |
| Check | A second program already re-derived the default. | None. |
| Cite | This walk plus the calculator. | Do not cite the chat list. |

The steps
1. Open the DTI calculator. 2. Read the formula. Above the line goes every payment you are required to make each month. Below it goes gross pay, before tax and deductions. The division gives a decimal, so multiply by for the percentage a lender quotes. 3. Leave the defaults if you want the checked example, or type yours. 4. Read the result above the inputs. 5. If a pair is involved, open the compare table.
Why the order matters
Finance is full of arithmetic that looks right. The convention has to be named before the number is useful. The longer how-to is how to calculate DTI.
The worked example
The default on the calculator is the first worked example. A second program re-derives it or the site cannot build. See DTI worked example.
