Three numbers, thirty seconds. Then see what it means and what a good rate looks like in your industry.
Your retention
At 76% you are in the 70%+ range often seen in subscription and B2B businesses, and well above the 25–30% commonly quoted for ecommerce. Those broad industry ranges are usually quoted over a year, so a monthly or quarterly rate will tend to read higher — your own quarterly rate last quarter is the fairer comparison.
A 10-point improvement means about 50 more of your 500 customers still buying at the end of the quarter. Add your average order value to see it in rupees.
Customer retention rate is the share of the customers you had at the start of a period who are still buying at the end of it. The formula is ((E − N) ÷ S) × 100: customers at the end, minus new customers won during the period, divided by customers at the start. Churn rate is 100 minus that figure.
How do you calculate
retention rate?
The calculator uses exactly these. The optional rupee outputs build on the first one.
Retention rate
Retention rate = ((E − N) ÷ S) × 100
E = customers at the end of the period
N = new customers acquired during the period
S = customers at the start of the period
Churn rate
Churn rate = 100 − retention rate
Revenue at risk
Revenue at risk = (S − (E − N)) × average order value × orders per customer per period
S − (E − N) = the customers you started with who stopped buying
What a 10-point improvement is worth
Value of 10 points = (S × 0.10) × average order value × orders per customer per period
Assumes = the extra customers kept order at your current average. Revenue, not profit. Capped at the customers you actually lost.
Rough customer lifetime value
Lifetime value ≈ average order value × orders per customer per period ÷ churn rate
Assumes = churn stays the same period after period, so an average customer stays for 1 ÷ churn periods
Repeat purchase rate — a different measure
Repeat purchase rate = (customers who bought more than once ÷ all customers) × 100
Note = it reads your order history rather than a start and end count, so it does not need a period — and it is not the same number as retention
Three worked examples,
with the arithmetic shown
Example 1
A quarter with heavy acquisition
- You started the quarter with 500 customers. You finished with 560. During the quarter you acquired 180 new customers.
- (560 − 180) ÷ 500 = 0.76
- Churn rate: 100 − 76 = 24%, which is 120 of your original 500 customers
Your retention rate is 76%.
Example 2
A D2C brand over one year
- 2,000 customers at the start, 1,900 at the end, 1,100 of them new: (1,900 − 1,100) ÷ 2,000 = 0.40 — retention 40%, churn 60%
- Customers lost: 2,000 − 800 = 1,200
- Revenue at risk: 1,200 × ₹900 average order × 2 orders a year = ₹21,60,000 a year
- A 10-point improvement: 2,000 × 0.10 = 200 more customers × ₹900 × 2 = ₹3,60,000 a year
Retention 40% — every ten points it rises is worth about ₹3,60,000 a year in revenue.
Example 3
A B2B distributor, month by month
- 120 accounts at the start of the month, 110 at the end, 14 of them new: (110 − 14) ÷ 120 = 0.80 — retention 80%, churn 20%
- Accounts lost: 120 − 96 = 24
- Revenue at risk: 24 × ₹45,000 average order × 1 order a month = ₹10,80,000 a month
- A 10-point improvement: 120 × 0.10 = 12 more accounts × ₹45,000 = ₹5,40,000 a month
Retention 80% a month — ten more points is worth about ₹5,40,000 a month.
What is a good
retention rate?
It varies enormously by industry, which is why your own number last period is a better yardstick than any average.
| Type of business | Retention commonly quoted | Why it sits there |
|---|---|---|
| Ecommerce and D2C | 25–30% | Many products are bought once, and the customer has no reason to return unless you give them one |
| Indian ecommerce, repeat purchase | ~25% | A common starting point for stores with no follow-up after the first order |
| Strong ecommerce operators | 70–75% | The same kind of store, with a reason to come back and a reminder at the right time |
| Subscription software, insurance and media | 70%+ | Billing renews by default, so leaving takes a decision |
| B2B distribution and wholesale | Often 70%+ | Accounts reorder on a cycle and switching supplier has a real cost |
Why your number might be wrong
Most retention figures that look surprising — good or bad — come from one of these six errors, not from the business.
- (01)
You left out new customers
Comparing 560 against 500 hides 120 lost customers. Always subtract the customers you won during the period.
- (02)
The period is shorter than your buying cycle
If people buy from you twice a year, a monthly rate counts most of them as lost when they are simply between orders.
- (03)
Start and end use different definitions
If a customer means ordered in the last 90 days at the start, it must mean exactly that at the end too.
- (04)
You counted contacts, not customers
Everyone on your WhatsApp or email list is not a customer. Count people who have actually bought.
- (05)
One buyer, two records
The same person with two phone numbers is counted twice — once as lost and once as new.
- (06)
You counted orders, not people
Ten orders from one wholesale account are one retained customer, not ten.
What to do about a low retention rate
Work out why customers left before you try to bring them back. A bad experience, no reason to return, forgetting you exist, a cheaper option and the need simply ending all look the same in the number, and each needs a different fix.
Then start with the customers closest to buying again: people who asked a price and went quiet, payment links that were never paid, and regular buyers who have missed their usual reorder. That is the cheapest revenue you have.
Measure the result against a holdout group that gets nothing, so you know what the work actually added rather than what it happened to be present for.
Questions about your retention number
Everyone who was an active customer on the first day — usually anyone who bought within their normal repeat window before that date. Pick one definition and keep it: if active means ordered in the last 90 days, use 90 days every time. Changing the definition between periods moves your retention rate more than anything you actually did.
Use the period that matches how often your customers normally buy. A monthly rate for a product people buy twice a year will look terrible for no real reason. Most ecommerce and D2C brands read best quarterly or yearly; B2B accounts that reorder every few weeks can use monthly. Whichever you choose, compare like with like.
Because customers at the end minus new customers came to more than you started with, or new customers came to more than the end count. Usually some new customers were counted as existing ones, or the three numbers cover different dates. Check they all use the same definition of a customer and the same period.
Customers lost — the ones you started with minus those still buying — multiplied by your average order value and the orders a customer places in one period. It assumes each lost customer would have kept ordering at your average for one more period. It is revenue, not profit, and a rough guide rather than a forecast.
It depends on where you start. A business with no follow-up at all has far more room than one already running win-back and reorder reminders. We use ten points because it is easy to reason about, not because it is a promised result. Whatever you try, measure the change against a holdout group so you know what the work actually added.
