Answer

Answer key: Stripe Fee worksheet

1. Amount to request: $144.49
1. The fee is also charged on whatever you add to cover it. So divide by the share you keep, not just add the fee
  $\frac{($140.00 + $0.30)}{(100% - 2.9%)}$ $= $144.49$
2. Check it: the fee on the rounded amount leaves you this much
  $$144.49 - $4.49$ $= $140.00$
3. So this is the lowest whole-cent amount to request
  $$140.00 + $4.49$ $= $144.49$
2. Amount to request: $123.48
1. The fee is also charged on whatever you add to cover it. So divide by the share you keep, not just add the fee
  $\frac{($120.00 + $0.15)}{(100% - 2.7%)}$ $= $123.48$
2. Check it: the fee on the rounded amount leaves you this much
  $$123.48 - $3.48$ $= $120.00$
3. So this is the lowest whole-cent amount to request
  $$120.00 + $3.48$ $= $123.48$
3. Stripe fee: $4.62
1. Stripe takes a percentage of the whole payment
  $$80.00 \times 5.4%$ $= $4.32$
2. The fee is that percentage plus any fixed fee, rounded to the nearest cent
  $$4.32 + $0.30$ $= $4.62$
3. Take the fee off the payment to see what reaches you
  $$80.00 - $4.62$ $= $75.38$
4. Stripe fee: $0.54
1. Stripe takes a percentage of the whole payment
  $$68.00 \times 0.8%$ $= $0.54$
2. The fee is that percentage plus any fixed fee, rounded to the nearest cent
  $$0.54 + $0.00$ $= $0.54$
3. Take the fee off the payment to see what reaches you
  $$68.00 - $0.54$ $= $67.46$
5. Amount to request: $90.73
1. The fee is also charged on whatever you add to cover it. So divide by the share you keep, not just add the fee
  $\frac{($90.00 + $0.00)}{(100% - 0.8%)}$ $= $90.73$
2. Check it: the fee on the rounded amount leaves you this much
  $$90.73 - $0.73$ $= $90.00$
3. So this is the lowest whole-cent amount to request
  $$90.00 + $0.73$ $= $90.73$
6. Amount to request: $124.53
1. The fee is also charged on whatever you add to cover it. So divide by the share you keep, not just add the fee
  $\frac{($120.00 + $0.30)}{(100% - 3.4%)}$ $= $124.53$
2. Check it: the fee on the rounded amount leaves you this much
  $$124.53 - $4.53$ $= $120.00$
3. So this is the lowest whole-cent amount to request
  $$120.00 + $4.53$ $= $124.53$
7. Stripe fee: $0.64
1. Stripe takes a percentage of the whole payment
  $$80.00 \times 0.8%$ $= $0.64$
2. The fee is that percentage plus any fixed fee, rounded to the nearest cent
  $$0.64 + $0.00$ $= $0.64$
3. Take the fee off the payment to see what reaches you
  $$80.00 - $0.64$ $= $79.36$
8. Stripe fee: $2.36
1. Stripe takes a percentage of the whole payment
  $$82.00 \times 2.7%$ $= $2.21$
2. The fee is that percentage plus any fixed fee, rounded to the nearest cent
  $$2.21 + $0.15$ $= $2.36$
3. Take the fee off the payment to see what reaches you
  $$82.00 - $2.36$ $= $79.64$
9. Amount to request: $120.97
1. The fee is also charged on whatever you add to cover it. So divide by the share you keep, not just add the fee
  $\frac{($120.00 + $0.00)}{(100% - 0.8%)}$ $= $120.97$
2. Check it: the fee on the rounded amount leaves you this much
  $$120.97 - $0.97$ $= $120.00$
3. So this is the lowest whole-cent amount to request
  $$120.00 + $0.97$ $= $120.97$
10. Stripe fee: $3.93
1. Stripe takes a percentage of the whole payment
  $$140.00 \times 2.7%$ $= $3.78$
2. The fee is that percentage plus any fixed fee, rounded to the nearest cent
  $$3.78 + $0.15$ $= $3.93$
3. Take the fee off the payment to see what reaches you
  $$140.00 - $3.93$ $= $136.07$
