    We price every subscription twice

    List price, then the price after its coupon, normalized to a month. The difference is what the coupon costs you, grouped by coupon and by product.

Each Stripe account gets full results and exports on 5 separate UTC days. Repeat scans on the same day use no extra credit (up to 5 scans per hour). Test-mode scans use no credits. After that, headline totals remain available. Each scan covers up to 5,000 active subscriptions.

What does this free Stripe tool show?

Discount reads your active and past-due Stripe subscriptions, normalizes each one to a monthly list price (yearly ÷ 12) and to the monthly price after its coupon (percent or fixed amount). The gap is what your coupons cost each month at today's prices, shown in total, per coupon and per product. Time-limited coupons stop counting when they end. It also lists the repeating discounts that end within the next 90 days.

Why do "once" coupons count as zero?

A coupon with duration "once" applies to the first invoice only. On a subscription that is already live, that invoice is behind you, so it no longer reduces your MRR. These subscriptions are counted separately so you can see how many there are.

What is a step-up?

When a repeating discount ends, Stripe bills the next invoice at full price. The step-up list shows who will see a higher charge and when, so you can tell them first, or decide to extend the discount. Price jumps that arrive unannounced are a common churn trigger.

Is net MRR here the same as in my Stripe dashboard?

Close, but not identical: Stripe's dashboard uses its own timing and definitions. This is a live snapshot of the current book at the moment of the scan, in your dominant currency, with other currencies converted at the latest spot rate.

Do I need to provide an email before seeing my results?

No. Connect your Stripe key and review the results without signing up. Email and company name are requested only when you export, and the file downloads straight away.
