A tape calculator you can check as you go

Use Figur's free tape calculator to add and subtract a list of amounts, review every entry, correct mistakes, and copy the running tape or total.

Keep a running tape of every amount

Each amount becomes its own tape row with a plus or minus sign. Figur recalculates the running balance whenever you add or remove a row, so you can review the full trail before treating the final total as complete.
