Twelve-month impact
Base case: 5% extra one-time churn among customers offered the increase. Compare with normal churn continuing in both cases.

Break-even extra churn: 16.7%
Among repriced customers, before renewal timing: price rise ÷ (1 + price rise). Your base case puts 4.4 expected customers and $5,318 of old-price ARR at risk by month 12. These are scenario outputs, not a churn forecast.
Compare churn cases
Conservative = 1.5× your extra churn assumption; upside = 0.5×. Capped at 100%.

What a SaaS price increase changes
A price change on an installed customer base has two moving parts: more revenue from customers who accept the new price and less revenue from customers who leave. The headline list-price increase is not the realized MRR gain. This calculator shows the difference as monthly and annual subscribers reach their renewal dates. If you are still choosing between flat, seat, usage or tiered packaging, start with the SaaS pricing model simulator.
Use your own retention history from the churn calculator and net revenue retention calculator to choose a range of extra churn. A scenario is a decision aid, not evidence of how customers will react.
The break-even churn formula
For a 20% increase, the threshold is 0.20 ÷ 1.20 = 16.7%. If 100 customers each pay $100 per month, 10 additional cancellations leave 90 paying $120, or $10,800 MRR versus the original $10,000. This simple formula describes one repriced cohort at a point in time. The full tool also applies your baseline churn to both cases and delays the increase until customers become eligible.
Compare the change with your current MRR and ARR. The break-even line only concerns recurring revenue. It does not measure conversion of new prospects or whether the price matches value delivered.
Why rollout and cash take longer
The tool assumes annual renewal dates are spread evenly through the year. Monthly customers can change price in the chosen rollout month after grandfathering. Annual customers change at their next renewal after that date, and their annual cash payment is recorded then. A six-month grandfathering period therefore delays most of the year-one gain; a late start can leave some annual customers at the old rate through month twelve.
The cash delta counts monthly collections and annual prepayments at renewal. It excludes unpaid invoices, taxes and new sales, so it is a planning view rather than a cash forecast. Put the result beside the runway calculator and financial model before changing a hiring plan.
Set assumptions you can test
Start with your actual customer count, blended ARPA, billing mix and baseline logo churn. Enter extra one-time churn as a separate assumption. The conservative and upside cases multiply that assumption by 1.5 and 0.5; they do not estimate elasticity. Segment-level prices, discounts and uneven renewal calendars need separate runs or your own contract-level model.
There is no market-median price increase prefilled here. Published SaaS price surveys can describe different customers, contract sizes and years. Use a source only when it matches your segment, note its publication date, and keep the input editable. The profit margin calculator can help assess whether revenue lift becomes durable gross profit.
A customer communication checklist
Before changing a contract price, review renewal and notice terms, decide which cohorts are grandfathered, and prepare a clear explanation of the value customers receive. Test the new offer with a small cohort, measure cancellations and downgrades separately, and revise the churn input with observed data. Track CAC payback if the higher price affects new-customer conversion as well as the installed base.
Keep the CSV with the assumptions used for each decision, then compare its twelve-month path with actual renewals. The exported values are arithmetic outputs, not a recommendation to raise prices.
What it means for financing
A price increase can raise contracted recurring revenue and gross profit if retention holds. If it weakens the customer base, a larger headline ARR may tell the wrong story. Lenders assess revenue quality and cash durability alongside the number, so bring both the base case and a downside case into a funding discussion.
