SaaS Price Increase Impact Calculator

Estimate the net monthly recurring revenue after a price rise by modelling impacted revenue, churn lift, and upgrade uptake.

Total monthly recurring revenue before the price change
Portion of MRR that will receive the new price
Percentage change applied to the impacted customers
Optional: extra churn triggered by the price change (defaults to 0% if blank)
Optional: share of retained customers moving to a higher plan (defaults to 0% if blank)
Optional: extra price uplift realised on the upgraded cohort (defaults to 0% if blank)

Model for revenue planning guidance. Validate projections against cohort analyses and finance-approved assumptions before publishing targets.

Examples

  • $120,000 starting MRR, 100% impacted, +12% price, 4% incremental churn ⇒ Projected MRR: $129,024.00 (Δ $9,024.00, 7.52%). Impacted segment retention: 107.52%.
  • $45,000 starting MRR, 80% impacted, +8% price, 6% churn, 15% upgrade adoption with 25% uplift ⇒ Projected MRR: $46,917.72 (Δ $1,917.72, 4.26%). Impacted segment retention: 105.33%.

FAQ

How should I estimate the incremental churn rate?

Use historical churn deltas from prior price changes or sensitivity analysis from customer surveys. Leaving the field blank assumes no additional churn.

What happens if only part of the customer base is repriced?

Adjust the impacted share percentage to match the revenue portion receiving the new price. The calculator keeps the remaining revenue unchanged.

How do upgrades influence the projection?

Set an upgrade adoption rate to represent the share of retained customers moving to a richer plan. Combine it with the upgrade uplift percentage to reflect the additional price paid after the switch.

Can I model a price decrease?

Yes. Enter a negative percentage in the price increase field. The calculator will show the corresponding drop in MRR and retention.

Additional Information

  • Result unit: USD (monthly recurring revenue).
  • Upgrade adoption and uplift defaults to 0% when left blank, so only the core price increase and churn effects are applied.
  • Impacted retention compares the post-change revenue from the affected cohort versus its starting contribution.
  • Use consistent currency and time basis for all inputs to keep comparisons accurate.
