GST Software Payback Calculator
Check how quickly GST or accounting software pays for itself through lower professional fees, staff time saved and late fees avoided.
Use this when deciding whether to move from manual filing (or full outsourcing) to software. Enter the first-year cost: subscription including GST, any setup or data migration charge and training time. If you are a regular GST-registered business, the GST on the invoice is normally claimable as input tax credit; enter it as the ITC amount. Composition taxpayers cannot claim ITC, so leave it at zero.
Net yearly saving is the honest number to get right: the reduction in professional fees, staff hours saved valued at their cost, and late fees or interest you expect to avoid, minus the renewal subscription you will pay every year after the first.
How it works. Net cost = first-year cost − ITC. The tool adds up yearly savings (growing at the rate you enter) until they exceed the net cost, and reports the payback in years and the net benefit over the period.
Worked example (illustrative). A ₹20,000 subscription plus 18% GST (₹3,600) = ₹23,600; ITC ₹3,600; net cost ₹20,000. If the software saves ₹14,000 a year after renewal costs, growing 5% a year, payback is about 1.4 years and the three-year net benefit is about ₹24,100.
Limits. Money's time value, price increases at renewal and the risk of switching later are ignored. Read choosing GST software before you sign an annual plan.
