Free Revenue Forecaster
Project your recurring revenue month by month. Start from today's MRR, set your growth, churn and expansion, and see the MRR, ARR and net retention that follow, on a chart and in a full breakdown.
New MRR as a share of current MRR.
Revenue lost each month.
Upsell from existing customers.
A forecast is a scenario, not a promise. It assumes your inputs hold steady, so revisit it as real numbers come in.
Build a forecast in four steps.
The forecaster projects your recurring revenue forward from where you are today. Set a few assumptions and it works out the MRR, ARR and retention for every month in your horizon.
Enter your current MRR
Start with the recurring revenue you bill this month. If you are not subscription-based, use your typical monthly revenue.
Set growth and churn
Add the new revenue you win each month, as a growth percentage or a fixed amount, then the share you lose to churn and gain from upsells.
Pick a horizon
Choose whether to look 12, 24, or 36 months ahead. Longer horizons show how small changes compound over time.
Read, compare and switch views
See your projected MRR and ARR month by month, along with net new revenue and retention. Switch between the chart and a full table, and turn on Compare to plot two churn rates side by side.
How the forecast maths works.
The monthly build
Each month starts from the last month's MRR and moves in three parts.
Churn = Begin MRR × churn %
Expansion = Begin MRR × expansion %
End MRR = Begin - Churn + Expansion + New
Example: start at 100, add 8% new, lose 3% to churn and gain 1% expansion, and you end the month at 106. That 106 is where next month begins, so it compounds.
Net revenue retention
What your existing base is worth over time, before any new sales.
NRR (monthly) = 1 - churn % + expansion %
ARR = MRR × 12
Example: 3% churn and 1% expansion leave 98% monthly retention. Over a year that compounds to roughly 78%, which is how much of today's revenue survives without winning anyone new.
The numbers a forecast turns on.
A recurring-revenue forecast is only as good as the metrics behind it. Here is what each one means and why it moves the curve.
Monthly recurring revenue. The predictable amount you bill every month from active subscriptions.
Annual recurring revenue. Your MRR run rate over a year, which is usually MRR times 12.
The share of recurring revenue you lose each month when customers cancel or downgrade.
Extra recurring revenue from existing customers who upgrade, add seats, or buy more.
What your existing base is worth over time after churn and expansion, before any new sales. Above 100% means it grows on its own.
Average revenue per user. Your MRR divided by the number of active customers.
From a forecast to a real revenue engine.
A forecast is a guess until you can measure against it. We build the subscription billing, revenue analytics and CRM software that tracks MRR, churn and expansion from live data, so you can see the real curve, catch churn early, and plan on numbers you trust.
Tracking customers too? See Tilarq CRM.
Common forecasting questions.
It is a free online tool that projects your future recurring revenue. You enter where you are today, plus how fast you grow and how much you lose to churn, and it works out your MRR and ARR for each month ahead, with a chart and a full breakdown.
Each month it starts from the previous month’s MRR, subtracts the revenue lost to churn, adds any expansion from existing customers, and adds new business. That gives the end MRR, which becomes the start of the next month. Repeat it across the horizon and you get the full curve.
MRR is monthly recurring revenue, the predictable amount you bill each month. ARR is annual recurring revenue, the same run rate expressed over a year. For most subscription businesses ARR is simply MRR times 12.
Churn is the share of recurring revenue you lose each month when customers cancel or downgrade. It matters because it compounds. A business losing 5% a month has to win far more new revenue just to stand still than one losing 1%, so small churn differences change the long-run curve dramatically.
Yes. Click Compare next to the churn field, then add as many churn rates as you want to weigh up, each plotted as its own line on the chart. The table lists every scenario side by side, along with the spread between the best and worst case each month. It is a quick way to see, in money, what cutting churn would be worth to your business.
Yes. Use the Chart and Table toggle above the results. The chart shows the shape of the growth curve, while the table gives the exact figures for every month, including the new revenue, churn and expansion that make up each step.
Expansion is extra revenue from existing customers who upgrade or buy more. Net revenue retention is what your current base is worth after churn and expansion, before any new sales. Above 100% means your existing customers grow your revenue on their own, which is one of the strongest signs of a healthy subscription business.
Use a percentage when your new business tends to scale with your size, which gives a compounding curve. Use a fixed amount when you add roughly the same new revenue each month regardless of size, for example from a steady sales team. The tool supports both, so you can compare them.
A forecast is a scenario, not a promise. It assumes your growth, churn, and expansion hold steady, which rarely happens in real life. Use it to compare options, stress-test churn, and see the shape of the curve, then revisit it as real numbers come in.
It varies a lot by market and customer size, so treat any single number with care. Many subscription businesses aim to keep monthly revenue churn in the low single digits, and the strongest ones pair low churn with expansion so net retention stays above 100%. Compare against your own trend rather than a headline benchmark.
Yes, with a bit of translation. Treat your starting MRR as typical monthly revenue, churn as the share of revenue that does not repeat, and new business as what you add each month. It is built for recurring revenue, but the same growth and attrition maths applies broadly.
Yes. Pick your currency at the top and every figure, the chart, and the table update to match. The maths is the same in any currency.
Yes on both. It is free, there is no sign-up, and it runs entirely in your browser. Nothing you type is sent anywhere or saved, so your numbers stay on your own device.
It is meant for quick scenarios and planning conversations, not for running your finances. Once you are billing real customers you want a system that tracks MRR, churn, and expansion from live data and reports on it automatically. That is the kind of software we build at Techliphant if you need it.
Disclaimer: This revenue forecaster is free and meant for planning scenarios and learning. It assumes your growth, churn and expansion stay constant, which real businesses rarely do, so the output is an estimate and not a projection you should bank on. None of this is financial advice. Sanity-check the numbers against your own data, or with a qualified professional, before you rely on them.
