SaaS Subscription Pricing Calculator

Subscription pricing models structure recurring revenue to maximize long-term customer value, minimize churn, and create predictable cash flow. Pricing strategy directly determines LTV, gross margin, and the ability to scale.

Key revenue formulas:

Monthly Recurring Revenue (MRR): MRR = Σ (Active Subscribers × Monthly Price per Tier)

Annual Recurring Revenue (ARR): ARR = MRR × 12

Average Revenue Per User (ARPU): ARPU = Total MRR / Total Active Subscribers

Gross Margin: Gross Margin % = (Revenue − COGS) / Revenue × 100% For SaaS, COGS includes hosting, payment processing, support. Target gross margin: 70–85%.

Pricing model options and formulas:

Per-seat pricing: Revenue = Seats × Price per seat Usage-based: Revenue = Units consumed × Price per unit Tiered: Revenue = Σ (subscribers per tier × tier price) Freemium conversion: Revenue = Free users × Conversion rate × Paid ARPU

Optimal price point estimate (van Westendorp method): Survey customers with 4 questions (too cheap, cheap, expensive, too expensive) to find the Acceptable Price Range — the overlap between “not too cheap” and “not too expensive” responses.

Price elasticity: Elasticity = % Change in Quantity / % Change in Price If elasticity > 1: reducing price increases revenue (elastic market) If elasticity < 1: price increases still grow revenue (inelastic market)

Worked example: SaaS tool with 3 tiers: Basic $19/mo (600 users), Pro $49/mo (300 users), Enterprise $149/mo (50 users). MRR = (600 × $19) + (300 × $49) + (50 × $149) = $11,400 + $14,700 + $7,450 = $33,550 ARPU = $33,550 / 950 = $35.32/user/month ARR = $33,550 × 12 = $402,600

Annual plan discount economics: Offering 2 months free (16.7% discount) on annual plans is standard. The immediate cash collection reduces churn risk by 50–60% and improves cash flow for reinvestment.

What this calculator does with that

It takes one headline monthly price, your annual discount, your subscriber count, and the share who pick annual, then reports blended MRR. Annual subscribers are counted at their discounted effective monthly rate, which is the honest way to book them: an annual customer paying up front is not worth the full sticker price each month.

Say you charge $29/month, give 20% off for annual, have 500 subscribers, and 40% of them take the annual plan.

Annual plan price = $29 × 12 × 0.80 = $278.40/year, an effective $23.20/month Split = 200 annual, 300 monthly MRR = (300 × $29) + (200 × $23.20) = $8,700 + $4,640 = $13,340 ARR = $13,340 × 12 = $160,080 All-monthly ARR would be 500 × $29 × 12 = $174,000, so the discount costs $13,920 a year

That last line is the one worth staring at. The discount is not free, and whether it pays for itself depends entirely on how much churn the annual commitment prevents. If your monthly churn is 5% and the annual plan drops it to near zero for a year, you come out well ahead. If your monthly churn is already 1%, you just handed away 20% of your revenue for nothing.
