--- title: Fintech App Metrics: KYC, Deposits, Metric Tree description: Fintech app metrics as a metric tree: cost per install, KYC completion, day 1, 3 and 7 deposit conversion, retention, ARPU, LTV and CAC, with a calculator. url: https://appmetricslibrary.com/verticals/fintech/ --- # Fintech app metrics The metrics that show whether a payments, lending, investing or savings app turns installs into funded, active customers, and how each one is calculated. **Short answer** The key fintech app metrics are cost per install, sign-up rate, KYC completion, first transaction rate by day 1, 3 and 7, monthly transacting users, retention and churn, ARPU, LTV, CAC and payback. Because KYC and first deposit sit between install and revenue, cost per funded customer matters more than CPI. ## What are the key metrics for a fintech app? The key metrics for a fintech app measure how many installs become verified, funded and regularly transacting customers, and what each of those customers costs and earns. - **Acquisition:** [cost per install](https://appmetricslibrary.com/metrics/cpi/) and [cost per action](https://appmetricslibrary.com/metrics/cpa/) at each funnel step. - **Activation:** [activation rate](https://appmetricslibrary.com/metrics/activation-rate/) to sign-up, [KYC completion](https://appmetricslibrary.com/metrics/kyc-completion-rate/) and [first transaction rate](https://appmetricslibrary.com/metrics/first-transaction-rate/). - **Engagement:** [monthly active users](https://appmetricslibrary.com/metrics/mau/) counted on transactions, and [stickiness](https://appmetricslibrary.com/metrics/dau-mau-stickiness/) in its weekly form. - **Retention:** [retention by week or month](https://appmetricslibrary.com/metrics/retention-rate/) and activity-based [churn](https://appmetricslibrary.com/metrics/churn-rate/). - **Monetisation:** [ARPU](https://appmetricslibrary.com/metrics/arpu/), [LTV](https://appmetricslibrary.com/metrics/ltv/), [CAC](https://appmetricslibrary.com/metrics/cac/) and [payback period](https://appmetricslibrary.com/metrics/payback-period/). **Funded account:** an account with a first deposit, payment or balance. Many fintech teams treat this, not the sign-up, as the moment a user becomes a customer. ## Which fintech onboarding steps lose the most users? In most fintech funnels the biggest losses sit between sign-up and the first transaction: KYC document capture, review time and the first deposit. Measuring started, submitted and verified KYC separately, then deposit conversion by day 1, day 3 and day 7, shows which of those steps to fix.

It is cumulative, so the day 7 rate includes everyone who deposited on days 1 to 6. ## How the fintech metrics connect Each gate divides the users who reach the next, so the cost of a funded customer is [CPI](https://linkrunner.io/glossary/what-is-cost-per-install?utm_source=appmetricslibrary&utm_medium=referral&utm_campaign=hub-fintech&utm_content=inline) divided by every conversion rate in turn. - **Cost per sign-up** = CPI ÷ install-to-sign-up rate. - **Cost per verified user** = cost per sign-up ÷ KYC completion (of sign-ups). - **Cost per funded customer** = cost per verified user ÷ first transaction rate. This is the media part of CAC. - **Payback** = CAC ÷ monthly gross profit per customer, which in fintech often builds slowly from fees, interest or interchange. The calculator runs the chain with example inputs. Replace them with your own to see which gate moves the cost of a funded customer most. > Interactive tool (metric calculator): runs in the browser at https://appmetricslibrary.com/verticals/fintech/#metric-calc.

Once volumes allow, optimising towards [KYC complete](https://appmetricslibrary.com/metrics/kyc-completion-rate/) or first deposit usually aligns spend with customers. - **Deposit timing.** Plot [first transaction rate](https://appmetricslibrary.com/metrics/first-transaction-rate/) at day 1, day 3 and day 7 for each weekly cohort. A curve that keeps rising after day 3 says reminders work; a flat one says the decision is made on day 1. - **Weekly, not daily, activity.** Investing, lending and insurance apps are not daily habits. Use weekly or monthly [retention](https://appmetricslibrary.com/metrics/retention-rate/) ranges and WAU/MAU rather than [DAU/MAU](https://linkrunner.io/glossary/what-is-stickiness-dau-mau-ratio?utm_source=appmetricslibrary&utm_medium=referral&utm_campaign=hub-fintech&utm_content=inline). - **Churn without a cancel button.** Most fintech churn is silence, not cancellation. Define activity [churn](https://appmetricslibrary.com/metrics/churn-rate/) as no transaction in 30 or 90 days and keep that window fixed. - **Revenue that arrives late.** Interest and fees accrue over months, so early [ROAS](https://appmetricslibrary.com/metrics/roas/) looks poor. Long-horizon, margin-based [LTV](https://appmetricslibrary.com/metrics/ltv/) is the fairer test of a channel. - **Long [attribution windows](https://linkrunner.io/glossary/what-is-an-attribution-window?utm_source=appmetricslibrary&utm_medium=referral&utm_campaign=hub-fintech&utm_content=inline).** KYC review can take days, so first transactions can land after short attribution windows close. Check the window before blaming a channel. ## Where fintech numbers go wrong - **Referral rewards counted as growth.** Cash rewards lift [referral share](https://appmetricslibrary.com/metrics/referral-install-share/) quickly, and attract reward hunters. Judge referral cohorts on funded accounts and retention, not installs. - **Sign-up as the denominator.** KYC completion measured from sign-ups mixes motivation with form friction. Report it from KYC started as well. - **Benchmarks as targets.** In Linkrunner's State of Mobile App Growth: India Startups 2026 report, the median fintech app turned about 21% of installs into sign-ups, and the median fintech CPI in that India report was about ₹21, with a wide spread between apps. Use your own week-on-week trend to set targets.

Some teams use value transacted per month instead. **How do you calculate fintech onboarding conversion on day 1, day 3 and day 7?** Take a weekly cohort of verified users and count how many made a first deposit by each day. Each rate is cumulative and uses the same cohort as its base. **Why is CPI a weak metric for fintech apps?** Because several gates sit between the install and revenue. Two channels with the same CPI can have very different KYC and deposit rates, so the cost per funded customer can differ several times over. **Should fintech apps measure DAU?** Only payments and daily-spend apps. For most fintech products, weekly or monthly transacting users describe real use better. **Does the calculator send my numbers anywhere?** No. It runs entirely in your browser, and nothing you type is stored or sent anywhere. **Why do tools report different values for the same metric?** Because definitions differ: what counts as active, which attribution window applies, whether organic users are included and how days are cut by timezone. Align the definition before comparing numbers.
