Calculators
Your numbers, worked out honestly
Grades, prep hours, course costs, loans, payback and deadlines — computed on your device from what you type. No built-in fees, rates or salaries, ever.
🧮 What these are — and aren't
- Arithmetic on the numbers you enter. The formula is printed under every result so a parent can check it.
- Nothing is looked up from the catalog and nothing is a prediction: no rank, cutoff, admission chance or salary forecast.
- Where the original pack had a built-in figure (an exchange rate, a city rent, a stipend) it was removed. You type the number from the official page; the hint says which page.
- Score tables (percentiles, TOEFL↔IELTS, PTE↔IELTS, ACT↔SAT, GMAT Classic↔Focus) and institution grade rules are served only once a named reviewer has checked them against the publisher. Until then those calculators say so, link the official source, and work only from what you type.
- A grade conversion is never a credential evaluation and a score comparison is never an equivalent: the result says which it is — rule, reference table, estimate, scenario, or not available.
- Nothing you type is saved or sent anywhere. Close the page and it is gone; copy or download the result if you want to keep it. A link from another page may carry a currency or a catalog figure in the address, never your own entries.
