MRR bridge

The calculator uses the numbers you enter. With 40000 start MRR, 3.5 churn %, 2.2 contraction %, 4.5 expansion %, 2500 new logo USD the result is $42,020.00 | $2,020.00. This is not ChartMogul.

How it works

MRR bridge in this calculator is start minus churn and contraction plus expansion and new logo. With 40000 start MRR, 3.5 churn %, 2.2 contraction %, 4.5 expansion %, 2500 new logo USD the result is $42,020.00 | $2,020.00.

end = start × (1 − churn − contraction + expansion) + new logo. net = end − start. The formula uses churn and expansion.

$42,020.00 | $2,020.00 is not ChartMogul. Another set of numbers gives $25,075.00 | $75.00, and a further set gives $75,190.00 | $5,190.00. Empty scenario fields do not change the result.

NRR answers a different question. LTV/CAC does too. Here 40000 start MRR, 3.5 churn %, 2.2 contraction %, 4.5 expansion %, 2500 new logo USD leave $42,020.00 | $2,020.00.

Type 40000 start MRR, 3.5 churn %, 2.2 contraction %, 4.5 expansion %, 2500 new logo USD and click Calculate. Two more ready sets sit under the form: $25,075.00 | $75.00 and $75,190.00 | $5,190.00.

Other numbers on the same labels move the result. The first example gives $42,020.00 | $2,020.00.

Formula

end = start × (1 − churn − contraction + expansion) + new logo. net = end − start.

How to use

  1. Type 40000 start MRR, 3.5 churn %, 2.2 contraction %, 4.5 expansion %, 2500 new logo USD.
  2. Leave the scenario fields empty if you do not have those numbers.
  3. Click Calculate. This set shows $42,020.00 | $2,020.00.
  4. The second example under the result is $25,075.00 | $75.00, the third $75,190.00 | $5,190.00.
  5. This is not ChartMogul.
