Learn how to effectively evaluate B2B SaaS investments with a thorough cost-benefit analysis.
Formula
const savings = inputs.annualManHoursSaved * inputs.averageHourlyRate;
const implementationCost = inputs.initialInvestment * (inputs.implementationTimeMonths / 12);
const totalCostFirstYear = inputs.initialInvestment + inputs.annualSubscriptionCost;
const totalSavingsFirstYear = savings - inputs.annualSubscriptionCost;
const roi = (totalSavingsFirstYear - implementationCost) / implementationCost;
const paybackPeriod = inputs.initialInvestment / savings;
const discountedSavings = totalSavingsFirstYear / Math.pow(1 + (inputs.discountRate / 100), 1);
const discountedCost = totalCostFirstYear / Math.pow(1 + (inputs.discountRate / 100), 1);
const netPresentValue = discountedSavings - discountedCost;
return {
totalSavingsFirstYear: totalSavingsFirstYear,

Cost-Benefit Analysis for B2B SaaS Investments projects Total Savings (Year 1), ROI (Year 1), Payback Period (Months) using Initial Investment, Annual Subscription Cost, Estimated Annual Man-Hours Saved, Average Hourly Rate of Employees Affected.

Use this finance calculator to compare scenarios before committing money, time, or a provider conversation.
The estimate combines Initial Investment, Annual Subscription Cost, Estimated Annual Man-Hours Saved and returns Total Savings (Year 1), ROI (Year 1), Payback Period (Months).
