Custom Calculator
Build your own calculation with named rows. Add or subtract fixed values, percentages, multipliers, or divisions — great for interest, fees, taxes, or splitting values into parts. Nest rows under a parent row to calculate against that row's value instead of the running total. Drag rows to reorder or nest, then save and share with a unique link.
| Drag | Name | Operation | Type | Value | Amount | Running Total | Actions |
|---|---|---|---|---|---|---|---|
| Total | 0.00 | ||||||
Drag the handle up/down to reorder rows — rows are evaluated top to bottom. Drag right (or use the button) to nest a row under the row above it: nested rows compute % of parent row, Multiply parent value, and Divide parent value against that parent row's amount instead of the running total. Drag left (or ) to un-nest. For top-level rows, Normal value adds/subtracts a fixed amount, % of subtotal applies a percentage of the running total, and Multiply / Divide subtotal scale the running total directly. Use the checkbox to temporarily exclude a row.
