SaaS Price Increase Calculator for Solo Founders
Free saas price increase calculator for bootstrapped founders. See net MRR after a price increase, how many customers you can lose and still stay flat, and whether your expected churn still leaves you ahead.
What is price raise impact on MRR?
Price raise impact is the change in monthly recurring revenue after you increase plan price and some customers cancel. A twenty-five percent sticker bump that costs you ten percent of logos is often a net win. A jump that triggers thirty percent churn can erase the raise — or worse.
Solo founders often fear the angry email more than the invisible discount of staying underpriced for years. This raise SaaS prices calculator makes the trade-off concrete: remaining customers × new price versus everyone × old price.
How to use this calculator
Enter paying customers, current price, new price, and the churn you expect from the raise. The tool shows current MRR, MRR after the hike, net change, customers lost, and the maximum churn you can afford before you break even.
Use the scenario table to stress-test optimistic and pessimistic cancel rates. Copy the link to share a scenario with a co-founder or to revisit after your thirty-day postmortem.

Why solo founders need raise math
Optimizing for logo count after a raise is how you talk yourself out of durable revenue. Eight customers at $39 can beat ten at $29. The same logic applies when existing customers churn: if remaining MRR is higher, the business got healthier even if the customer count dipped.
Model the raise before you write the announcement. If breakeven churn is twenty-five percent and you only expect a handful of cancels, ship it. If your gut says half the base will leave, shrink the jump or fix value first — then rerun the numbers.
Frequently asked questions
How do I calculate the impact of a SaaS price increase?
Take current MRR (customers × old price), estimate how many customers leave because of the raise, then multiply remaining customers by the new price. The difference is your net MRR after the price hike. This saas price increase calculator turns that into dollars so you can see whether the raise still wins after churn.
How much churn can I afford when I raise prices?
Breakeven churn is roughly 1 − (old price ÷ new price). Moving $29 to $39 lets you lose about 25.6% of customers and still match old MRR. If expected churn from the raise stays under that line, net MRR goes up. That is the core of price hike churn impact math for solo founders.
Should I raise prices for existing customers or only new ones?
Start with new customers when you can. You learn whether the market accepts the sticker without waking every invoice. Use this calculator when you are ready to bring existing customers up — plug in expected cancel rate and see net MRR after price increase before you send the email.
What size price increase is safe for a micro-SaaS?
Under about thirty percent usually reads as a routine update ($29 → $39). Bigger jumps need a clearer product story. Run the solo founder price raise math at a few churn assumptions before you commit — a modest raise with low churn beats a dramatic jump that spikes cancellations.
