PMT in a worksheet

=PMT(rate, nper, pv, [fv], [payment_type])

Calculates the payment for a loan based on constant payments and a constant interest rate.

When to use PMT

Use PMT when you need to calculate the payment for a loan based on constant payments and a constant interest rate.

  • Model loans, payments, and time-value calculations.
  • Build finance workflows in a spreadsheet.

How PMT works in Quadratic

In Quadratic, PMT follows the syntax PMT(rate, nper, pv, [fv], [payment_type]). The function works inside Quadratic formulas and can be combined with spreadsheet ranges, tables, and other formulas.

Common PMT mistakes

Most PMT issues come from mismatched argument types, ranges that do not cover the intended data, or optional parameters being omitted when the default behavior is not what you expected.

  • Check each required parameter before copying the formula across a sheet.
  • Confirm that ranges line up with the rows or columns you intend to analyze.
  • Use Quadratic AI to explain or debug the formula when the result looks wrong.

Struggling with formulas? Use Quadratic AI.

Spreadsheet formulas are powerful, but they get painful fast. A PMT formula can start simple, then turn into logic that is hard to understand, easy to break, and difficult to share with the rest of your team.

Quadratic AI helps you write formulas, explain formula logic, debug broken references, and move beyond formulas when advanced analysis needs Python, SQL, charts, or connected data.

Why formulas slow teams down

  • Long formulas become hard to read, understand, and trust.
  • Formula logic breaks when rows, columns, or assumptions change.
  • Manual updates make dashboards and reports fragile over time.
  • Complex formulas are difficult to explain, review, and share with teammates.
  • Advanced analysis quickly outgrows formula-only workflows.
