How to calculate PMI step by step
By Jude Wallis
A step-by-step walk for PMI 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 | Do not cite the chat list.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 PMI calculator. 2. Read the formula. is the loan, the annual PMI rate as a decimal, the original purchase price, the amortised balance. The 80 percent threshold is the borrower-request cancellation point under US rules; automatic cancellation sits a little later. 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 matching compare page.
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 PMI.
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 PMI worked example.
