Nigeria's standard VAT rate is 7.5%, and there are two different sums people confuse. To add VAT on top of a price, multiply by 0.075 and add it — ₦100,000 becomes ₦107,500. To find the VAT already inside a price, divide by 1.075 — ₦107,500 contains ₦7,500 of VAT.
The free VAT calculator at wadmaster.com/vat-calculator does both. Inside WadMaster, VAT is set per line item on an invoice and totals automatically.
Yes. The invoice generator, receipt generator, VAT calculator, withholding tax calculator and profit margin calculator are all free with no account, no card, and no limit on how many documents you make. There is no trial that expires and nothing to cancel.
No. Every tool at wadmaster.com/tools works without signing up. An account is only for the part the tools cannot do: keeping a record of what you sent, seeing who has paid, and chasing what is still outstanding.
Yes, you can send the free invoice or receipt PDF to a real customer, but it does include WadMaster branding in the document footer. It is not a translucent watermark across the page. Your business and transaction details remain the main document content. Inside a WadMaster account, Free and Starter invoices also keep the WadMaster line, and Pro removes it.
