Invoice Payment Calculator
Track partial payments and remaining balances.
When clients pay in installments or deposits, it is easy to lose track of what is still owed. Enter the invoice total and the payments received to see the remaining balance and the percentage paid.
The early-payment field shows what the balance would be if you offer a discount for paying quickly — for example 2/10 net 30, which means 2% off if paid within 10 days, otherwise the full amount within 30.
Formula
Balance = Invoice total − PaymentsPercent paid = Payments ÷ Total × 100Early-payment price = Balance × (1 − Discount %)
Example
A $4,800 invoice with $1,500 paid has a $3,300 balance (31.25% paid). With a 2% early-pay discount the client would pay $3,234.
