Formula Used
Estimated Service Total = Service Hours × Hourly Rate
Billed Value = Manual Billed Amount, otherwise Estimated Service Total + Rebill Expenses
Gross Invoice Value = Billed Value + Tax Amount
Net Invoice Value = Gross Invoice Value − Discounts − Refunds − Write-offs
Outstanding Balance = Net Invoice Value − Paid Amount
Collection Rate = Paid Amount ÷ Net Invoice Value × 100
Average Invoice Value = Billed Value ÷ Total Invoices
Estimated DSO = Outstanding Balance ÷ Net Invoice Value × Reporting Days
Overdue Share = Overdue Amount ÷ Outstanding Balance × 100

FAQs
1) What does this calculator summarize?
It combines invoice counts, billed value, taxes, discounts, refunds, collections, overdue exposure, and average invoice size into one report. This helps freelancers review billing performance without manually combining figures from several invoice records.
2) Should paid, overdue, and draft invoices equal total invoices?
Usually yes, unless you also have open invoices that are sent but not yet due. The calculator flags counts that exceed total invoices, so you can correct input mistakes before relying on the report.
3) What happens if I leave billed amount at zero?
The calculator automatically estimates billed value using service hours, hourly rate, and rebill expenses. This is useful when you want a quick report from workload data instead of finalized invoice totals.
4) Why include discounts, refunds, and write-offs?
These adjustments reduce collectible revenue. Including them improves report accuracy and shows whether pricing decisions, client concessions, or unpaid losses are shrinking the real value of invoiced work.
5) What does overdue share mean?
Overdue share measures how much of your outstanding balance is already late. A higher percentage suggests greater collection risk and signals that payment follow-up may need stronger attention.
6) How is DSO estimated here?
This version uses outstanding balance divided by net invoice value, then multiplies by reporting days. It gives a quick estimate of collection speed, not a full accounting-grade receivables model.
7) Can I use another currency?
Yes. Enter any currency symbol or short label, such as $, €, £, Rs, or AED. The calculator uses that symbol across the report output.
8) What should I do if collection rate is low?
Review overdue clients, shorten payment terms, send reminders earlier, reduce billing delays, and monitor discounts or write-offs. Low collection rate usually points to process issues, pricing pressure, or weak follow-up.
