How to Use This Tool
Enter your initial SaaS investment, expected monthly revenue increase, ongoing monthly cost, and gross margin percentage. Select a calculation method—simple payback for a quick estimate or discounted payback for a more conservative view. Click Calculate to see the payback period and related metrics.
Formula and Logic
For simple payback, the formula is: Payback Period (months) = Initial Investment / Net Monthly Gain. Net Monthly Gain = (Monthly Revenue × Margin%) - Monthly Cost. For discounted payback, we use a 5% annual discount rate to account for the time value of money, applying the present value formula iteratively.
Practical Notes
- Consider your pricing strategy: Higher margins shorten the payback period.
- Factor in trade terms like net-30 or net-60 payment delays, which can affect cash flow.
- Use market benchmarks—typical SaaS payback periods range from 6 to 18 months for small businesses.
- For e-commerce sellers, include platform fees and shipping costs in ongoing monthly costs.
