How to Determine the Optimal Flat Rate for My SaaS Product

Author: Pamela Martinsek, VP of Strategy

Reviewed by: Ioana Grigorescu, Content Manager

To identify an appropriate flat rate for your SaaS product, measure the average value provided across your entire user base and roll it into a single, predictable monthly or annual fee. This strategy will avoid complexity, allowing for shorter sales cycles and simplifying financial forecasting.

 

By following this guide, you’ll use the analytical framework required to accurately price your software for long-term profitability.

Step 1

Quantify the Value Metric and Average Usage

Before settling on a single price point, identify the primary metric that drives value for your users, such as data processed, messages sent, or contacts managed. Precision is key. Understanding usage distributions is necessary to prevent heavy users from eroding your margins.

 

  • Audit your telemetry: Review the last 60 days of application data.
  • Find the median: Identify the middle ground of usage across your entire customer base.
  • Set the anchor: If 80% of your users leverage only 20% of your maximum resources, anchor your flat rate slightly above the median, ensuring you capture the value provided to the majority of your users.

Infrastructure Cost (Avg)

Standard

$15.00

Power User

$85.00

 

Flat pricing is most effective when the marginal cost of serving a power user doesn’t exceed your set price. With a COGS calculator, make your margins healthy across all user segments and always protect your bottom line.

Flat Pricing vs. Per-Seat and Usage Models

Selecting the proper SaaS pricing strategy requires a strong self-assessment of your product’s core utility.

 

Ask the difficult questions and use this checklist to decide if a flat rate is right for your business:

 

  • Collaboration: Does my software promote teamwork? If yes, flat pricing discourages user hoarding.
  • Predictability: Is my infrastructure cost stable? If costs are predictable, flat-rate pricing is a good fit.
  • Customer Experience: Do customers experience billing shock with variable invoices? If so, flat-rate pricing will increase retention.

 

Analyze your projected revenue with flat-rate pricing as compared to tiered pricing or a per-seat model. Industry standard benchmarks indicate that companies who use fixed-rate pricing will see higher initial conversion rates. However, they also may see a 15-20% lower expansion revenue compared to usage-based billing models. Growth requires balance.

Tip

Consider per-user pricing only when adding more users directly escalates support and/or infrastructure burden. If not, a flat rate is usually the more attractive choice for B2B SaaS.

Step 3

Calculate the Breakeven Plus Margin

A flat-rate pricing model must account for Customer Acquisition Cost (CAC) and the total lifetime of the account. You cannot easily upsell more seats later. Your initial price must be robust from day one.

 

Apply the following formula to find your target price:

 

Price = (PaybackPeriodMonthlyCAC​) + Servicing Cost + Desired Margin

 

A startup with a $1,200 CAC and a 12-month payback period will require a minimum flat rate of $100/month. Validate your specific numbers with a CAC payback period calculator.

Step 4

Validate with Shadow Testing

Before committing to a public flat-rate price, verify your assumptions with a shadow or A/B test on your pricing page. Do not guess.

 

  • Split your traffic by directing 50% of your visitors to a page featuring your new flat rate, and the other 50% can be directed to your old model.
  • Analyze data by measuring the conversion rate and the Time to Conversion for both groups.
Tip

Use price anchoring to show the value of your flat rate. If a variable plan looks like it could cost $500/month for a large team, a $200/month flat rate will seem much more valuable.

Step 5

Implement an Annual Discount Structure

Flat-rate models will significantly benefit from annual commitments. These contracts lock in revenue and provide the much-needed upfront cash flow. This is a win-win situation.

 

  • Incentivize: Offer a 15-20% discount for annual billing to boost Annual Recurring Revenue (ARR).
  • Reduce Churn: Standard industry benchmarks show that annual prepayments can reduce SaaS churn up to 10% compared with month-to-month billing.
Tip

Have your service level agreement offer price adjustments with a 30-to-60-day notice, which will protect your business against any future inflation.

How PayPro Global can help

PayPro Global platform also supports discounts, cross-sells, upsell as well as revenue recovery features, like automated dunning and card updater services, to keep customers from payment failures. 

Conclusion

You’ll find that the optimal flat rate is found at the intersection of customer affordability and long-term service cost. By closely studying your customer usage patterns and carefully comparing flat pricing to tiered pricing, billing friction can be eliminated, and accelerated growth can be achieved. To successfully implement, fully understand the Customer Acquisition Cost (CAC), and test price sensitivity. Consistently monitor the chosen rate to achieve a healthy LTV to CAC ratio.
